Distribution and timing of spawning Faroe Plateau cod in relation to warming spring temperatures

ABSTRACT: The Faroe Plateau cod stock has been in a poor state since 2005, while temperatures in the region have been increasing. However, the importance of distributional changes in contribution to the poor stock size and the mechanisms that drive the distribution of spawning Faroe Plateau cod are still not clear. Density dependent processes and temperature limitations imposed due to the narrow thermal niche for cod during spawning are two potential drivers for the geographical distribution of spawning cod. We analyse the changes in the geographical location, spawning area, timing of spawning and realised temperature niche in relation to abundance and temperature. Distributions were modelled using generalized additive models (GAM) based on CPUE and bottom temperature data from Spring Bottom trawl survey. We can clearly separate the two main spawning areas of the Faroe Plateau cod and show that there are no indications of density dependence effects on the distribution within these spawning areas. However, we found both a geographical shift in the north-eastern direction and a shift in the timing of spawning in the northern area, while no changes in distribution or timing of spawning were found within the western spawning area. Both shifts were significantly correlated with temperature, leading us to conclude that temperature plays a key role in the spatial and temporal dynamics of the Faroe Plateau cod. However, due to the limited data of this study, future studies should re-examine the mechanisms controlling the distribution of spawning cod when a longer timeseries is available.

Temperature influence on roe fertilization in Atlantic Salmon aquaculture

ABSTRACT: Today the Atlantic salmon is breed in fresh water facilities on land and in marine environmentaround the world. In aquaculture the roe are fertilized and hatched in fresh water facilities. Theseare sold to marine farms as eyed roe or fry. In the roe production there are many factors affecting the production. One of these factors is the water temperature. In the Faroe Island Fiskaaling is the only company fertilizing and selling roe to the marine farms. The aim of this experiment is to examine how the water temperature influences the fertilization percentage of roe in Atlantic salmon aquaculture. Addition to the set-up of instruments, there were 16 cylinders made for the project. Two experiments, fertilizing roe in 7 different temperatures, were made. In addition to the experiment, data over 3 years from Fiskaalings fertilizations were added to the analysis. In the data analysis the temperature influence on the fertilization percentage, the difference in fertilization percentages when using gonads and milt and influence of day degrees on the fertilization temperature were examined.

Population genetics of house sparrow (Passer domesticus) in the Faroe Islands

ABSTRACT: Summary Genetic studies of house sparrows were conducted at eight sites (in 5 towns or cities) in the Faroe Islands in 2017-2018. Using PCR and fragment analysis, genetic information on Faroese house sparrows was provided. Population genetic differentiation within and between subpopulations is often indicated by various statistical indexes. Fixiation Index, FST, indicates differentiation between subpopulation relative to the total population. FIS indicates differentiation within populations. FIT indicates the total deviation for each individual relative to the total population, and is dependent on the values of FIS and FST. The FST result indicated a small to moderate genetic differentiation between populations, which may indicate several invasions of house sparrow to the Faroe Islands - one invasion from Svínoy and one from Suðuroy, which sinche has spread to the rest of the Faroe Islands. In general, the FIS and FIT results gave an indication of a decrease in heterozygotes and a slightl indication of inbreeding. Compared with other foreign studies, the Faroese house sparrow populations had a small number of alleles, but the alleles which are represented are comparable within the allele size found in other studies. The results follow up hypothesis presented by Jensen's and Kampp's (1997) that the Faroese house sparrow has spread from at least two founder populations. However, a larger investigation from several sites and birds is required to conclude this hypothesis.

Population genetics of house sparrow (Passer domesticus) in the Faroe Islands

ABSTRACT (FAROESE): Ein genetisk kanning af gráspurvum varð framd í 2017-2018 í átta ymiskum støðum (í 5 bygdum/býum) í Føroyum. Við PCR og fragmentanalysu var tað møguligt at fáa arvaligar upplýsingar út frá reinsaðum gráspurva DNA prøvum. Populationgenetiskar differentieringar í eini population og millum subpopulationer vera funnar við hjálp av ymiskum hagfrøðiligum indeksum. Fikseringindeks, FST, sipar til differentiering millum subpopulation i mun til tí totalu populatiónina. FIS vísir á differentiering innan populatiónir. FIT bendir á tað samlaða fráviki fyri hvørt individ relativt til tí totalu populatiónina, og avhongur av FIS og FST virðunum. FST úrslitið bendi á lítlan til rímiligan arvaligan mun millum populatiónirnar, sum kan merkja fleiri innræsir av gráspurvum í Føroyum – ein innrás úr Svínoy og ein úr Suðuroy, sum síðan hevur spjatt seg til restina av landinum. Generelt gav FIS og FIT eina ábending um fall av heterozygotum og eina lítla ábending um innannøring. Samenborið við aðrar útlendskar verkætlanir hava tær føroysku populatiónirnar eitt lítið tal av ílegum, men ílegurnar sum vóru umboðið, vóru innan somu ílegustøddarrað sum útlendskar verkætlanir. Úrslitini góvu eina lítla ábending um, at hypotesan hjá Jensen og Kamp (1997), at gráspurvurin er komin út frá minst tveimum uppruna populatiónum, men ein størri kanning má gerast fyri fleiri bygdir og býir og eitt størri tal at prøvum, fyri at kunna halda fast við niðurstøðuna.

Hunting of hare in the Faroe Islands in 2017

ABSTRACT: This is the sixth yearly census of hares hunted in the Faroe Islands. The hunting season is from 2 November to 31 December. The first census was conducted in 2012. The 2017 survey is based on data collected through the webpage “haran.fo”, which was created for this purpose. The investigation is based on information from 780 distinct hunting expeditions carried out in 263 outfields covering most of the Faroe Islands. In the present overview, 6,409 hares are registered as shot in the Faroe Islands. Based on this, I estimate the total number of hunted hares as being around 6,500 animals in 2017. Half of the hares were shot in 35 outfields. Half of these, i.e. 1,689 hares, where shot in 13 of the best outfields. In the 20 best hunting fields, a total of 2,279 hares were shot, corresponding to 36% of the hunted hares. The most successful hare-hunters in the Faroe Islands in 2017 were those from the outfield ‘Skálatoftahaga’ belonging to the village Skálatoftir. In total, they shot 280 hares in 7 trips. In second place were those from ‘Neshaga’, in the village of Vestmanna, with 172 hares in total in 14 trips. Number three were those from ‘Norðurtriðingur – Norðaripartur’ in village Sørvágur. They shot 146 hares in 10 hunting expeditions. However, if the hunting statistics are adjusted by the number of trips and shots, then the top-3 list changes. Then the field ‘Bergið’, belonging to the village Árnafjørður was the most successful. In this field a single man shot 64 hares in two trips, on average 32 hares per gun per day. Number two would be the field ‘Myrkjanoyrarhagi’, belonging to the village of Klaksvík, where the average outcome was 13.5 hares per gun per day. Number three was the field ‘Byrgið’ in village Kunoy, where a single man shot 11 hares in one day. Overall, 3.18 hares where shot per gun per day in the Faroe Islands in 2017, compared to 2.38 in 2016, 2.36 in 2015, 3.1 in 2014 and 2.9 hares per gun per day in 2013. Most of the hares were shot on the island of Streymoy with a total of 2,736, corresponding to 43% of the hunted hares in the Faroe Islands in 2017. On the island Vágar, 1,351 hares were shot in total, 869 on Eysturoy and 695 hares on the island of Borðoy. The village Vestmanna on the island Streymoy is, as in the previous years, the place where most hares were shot in 2017. In total, they shot 693 hares on 59 trips. On the first hunting day (Thursday 2th November) 681 hares were shot in 50 fields. On the first Saturday, 4th November, 939 hares were shot in 72 fields. During the 780 individual hunting trips in 2017, the hunting success ranged from 0 to 92 hares on each trip. The most common success rate was between 1 and 4 hares on a single day. Over the whole season, 8.14 hares were shot on an average a trip. This is somewhat more than in both 2016 and 2015, when on average 6.40 and 6.23 hares, were obtained per trip, respectively, but lesser than both in 2014 and 2013 when they shot 8.12 and 8.2 hares on average during each trip, respectively. The number of hunters on a trip ranged from 1 to 17. On half of the trips, an average of 2.0 or fewer hunters participated, in 252 cases (32%), the hunter was alone. Only men hunt hares in the Faroe Islands.It is estimated that approximately 900 distinct hunters participated in hare-hunting in the Faroe Islands in 2017, corresponding to around 4% of the male population. In 2016, 900 hunters participated, 800 in 2015, and in 2014, 1,200 hunters.

Shelters can negatively affect growth and welfare in lumpfish if feed is delivered continuously

ABSTRACT: Due to the socioeconomic importance of salmon farming in the North Atlantic and the economic impact of sea lice in this industry, there is high demand for novel pest control methods. One such method is the use of cleaner fish to remove the lice from the salmon. A cleaner fish that has recently gained in popularity due to its ability to work in cold water, is the lumpfish (Cyclopterus lumpus). This fish varies in efficiency, but when mortality is low and cleaning optimal, the fish are successful in keeping parasite burdens low. However, there is some concern for the welfare of lumpfish in the industry, because mortality is often high. This is sometimes attributed to inadequate feeding and shelter. Here we compare growth, body condition, and fin health of fish reared for four weeks in a crossed treatment design crossing shelter availability (shelter vs none) and feed delivery method (manual meal time feeds and continuous automated feeding). In terms of weight gain, shelter availability interacted with feeding method, with fish that had access to shelters and were fed using automated feeders gaining less weight than other fish. Fin health was not affected, but body condition was lowered both by access to shelter and being fed continuously. The results indicate a need to carefully consider how feeding method and shelter use is combined, both in cages and during rearing on land.

Hunting of hare in the Faroe Islands in 2016

ABSTRACT: This is the fifth yearly census of hares hunted in the Faroe Islands. The hunting season is from 2 November to 31 December. The first census was conducted in 2012. The 2016 survey is based on data collected through the webpage “haran.fo”, which was created for this purpose. The investigation is based on information from 451 distinct hunting expeditions carried out in 187 outfields covering the most of the Faroe Islands. In the present overview, 2,950 hares are registered shot in the Faroe Islands. Based on this, I estimate the total number of hunted hares has been around 3,500 animals in 2016. Half of the hares were shot in 35 outfields. Half of these, i.e. 728 hares, where shot in 13 of the best outfields. In the 20 best hunting fields, a total of 1,024 hares were shot, corresponding to 35% of the hunted hares. The most successful hare-hunters in the Faroe Islands in 2016 were those from the outfield ‘Kvíggjarhamarshaga’ belonging to the village Saksun. In total, they shot 90 hares in 7 trips. In second place were those from ‘Strandarhaga”, in village Strond, with 69 hares in 5 trips. Number three were those from ‘Fjalli” in village Kvívík. They got 68 hares in 7 hunting expeditions. However, if hunting statistics is adjusted by number of trips and shots, then the top-3 list changes. Then the field ‘Bergið’, belonging to the village Árnafjørður was the most successful. In this field a single man shot 10 hares in a single trip. Number two would be the field “Miðhagi + Líðarhagi” belonging to the village Norðoyri, where a single man shot 8 hares in a single trip. Number three was the field “Norðastifjórðingur” in village Sandur, where a single man shot 7 hares one day. Overall, 2.38 hares where shot per gun per day in the Faroe Islands in 2016, compared to 2.36 in 2015, 3.1 in 2014 and 2.9 hares per gun per day in 2013. Most hares were shot on the island Streymoy with a total of 1,275, corresponding to 43% of the hunted hares in the Faroe Islands in 2016. On the island Vágar, 465 hares were shot, on Eysturoy 462 and on the island Borðoy 333 hares. The village Vestmanna on the island Streymoy is, as in the previous years, the place where most hares were shot in 2016. In total, they shot 278 hares on 44 trips, but this is only a fourth of the hares hunted in 2014, when they shot 1,120 hares on 74 trips. On the first hunting day (2th November) 598 hares were shot in 39 fields. This is 20% of the catch in 2016 and 9% of the trips. On the last hunting day (31st December), a total of 282 hares were shot in 52 fields. On the 451 individual hunting trips in 2016, the hunting success ranged from 0 to 50 hares on each trip. The most common success rate was between 1 and 4 hares on a single day. Over the whole season, 6.40 hares were shot in average on a trip. This is somewhat more than in 2015, when in average 6.23 hares were obtained per trip, but lesser than both in 2014 and 2013 when they got 8.12 and 8.2 hares in average on each trip, respectively. The number of shooters on a trip ranged from 1 to 17. On half of the trips, an average of 2.0 or fewer shooters participated, in 143 cases (32%), the hunter was alone. It is estimated that approximately 700 distinct shooters participated in hare-hunting in the Faroe Islands in 2016, corresponding to 3% of the male population. In 2015, 800 hunters participated and in 2014, 1,200 hunters.

Hunting of hare in the Faroe Islands in 2016

ABSTRACT (FAROESE): Hetta er fimta frágreiðingin, sum eg skrivi um haruveiðuna í Føroyum. Fyrsta royndin var gjørd í 2012. Í yvirlitinum eru tilsamans 2.950 harur skrásettar at vera skotnar í Føroyum í 2016. Út frá hesum meti eg, at samlaða talið av harum, sum vórðu skotnar í Føroyum í 2016, hevur verið umleið 3.500. Kanningin byggir á tøl frá tilsamans 451 harutúrum í 187 hagapørtum kring landið. Helvtin av harunum vórðu skotar í 35 hagapørtum, av hesum vórðu 728 harur, tað er 25%, skotnar í 13 hagapørtum. Í 20 teimum bestu haruhøgunum skutu teir tilsamans 1.024 harur, sum er 35% av samlaðu veiðuni í Føroyum í 2016. Raskastir at skjóta harur í Føroyum í 2016 vóru teir, sum skutu í Kvíggjarhamarshaga í Saksun. Teir skutu tilsamans 90 harur, sum teir fingu á 7 túrum. Teimum á baki vóru teir í “Strandarhaga” á Strond á Borðoynni, við 69 harum á 5 túrum. Á triðja plássi vóru harumenninir í “Fjalli”, sum er partur á Ognarhaganum í Kvívík. Teir fingu 68 harum á 7 túrum. Verður hædd tikið fyri, hvussu nógvir túrar vórðu gingnir í hvørjum haga og hvussu nógvir skjúttar vóru við hvønn túrin, broytist úrslitið. Eftir hesum útrokningarháttinum, lá best fyri í hagapartunum “Bergið” í Árnafirði. Í hesum hagunum varð bara skotið tann eina dagin, har ein einsamallur maður fekk 10 harur. Næstbestur var “Miðhagi + Líðarhagi” á Norðoyri, har ein einsamallur maður ein dag fekk 8 harur. Á triðja plássi var hagin “Norðastifjórðingur” á Sandi, har ein einsamallur maður ein dag fekk 7 harur. Fyri alt landið vórðu skotnar 2,38 harur pr. byrsu hvønn dagin. Hetta er á leið tað sama, sum í 2015, tá miðalveiðan var 2,36 harur pr. byrsu hvønn dagin, men munandi minni enn í 2014, tá veiðan var 3,1 harur pr. byrsu hvønn dagin, og eisini minni enn í 2013, tá miðalveiðan var 2,9 harur pr. byrsu hvønn dagin. Flest harurnar vórðu skotnar á Streymoynni, íalt 1.275 harur, sum er 43% av samlaða talinum av harum, sum vórðu skotnar í Føroyum í 2016. Í Vágum skutu teir 465 harur, í Eysturoynni 462 og á Borðoynni 333 harur. Vestmanna er, eins og undanfarin ár, tann bygdin í Føroyum, har flestu harurnar vórðu skotnar í 2016. Tilsamans skutu vestmenningar 278 harur á 44 túrum, men hetta er bert ein fjórðingur av tí, sum teir skutu í 2014, tá vestmenningar skutu 1.120 harur á 74 túrum. Fyrsta dag, loyvt var at skjóta haru í 2016, var mikudagin 2. november. Hendan dagin fingu teir tilsamans 598 harur, sum vórðu skotnar í 39 hagapørtum kring landið. Hetta var eisini nógv tann besti einstaki harudagurin í árinum, og fingu teir 20% av samlaðu árligu veiðuni hendan dagin og gingu 9% av samlaða túratalinum. Seinasta dag, 31 desember, vórðu skotnar 282 harur í 52 høgum. Á teimum 451 harutúrunum, sum vórðu gjørdir í 2016, var veiðan millum 0 og 50 harur hvønn túrin. Vanligast var at fáa 1 til 4 harur á einum túri. Í miðal vórðu 6,40 harur skotnar á hvørjum túri, sum er eitt sindur meira enn í 2015, tá teir i miðal fingu 6,23 harur hvønn túrin, men minni enn í bæði 2014 og 2013, tá miðaltalið var ávikavist 8,12 og 8,2 harur pr. túr. Talið av skjúttum á hvørjum harutúri í 2016 var millum 1 og 17. Helvtin av túrunum vóru teir 2 ella færri skjúttar á hvørjum túri. 143 ferðir (32%) var bert ein maður og skeyt. Mett verður, at í 2016 skutu umleið 700 ymiskir mans harur í Føroyum. Hetta er eitt sindur færri enn í 2015, tá einir 800 mans skutu, og nógv minni enn í 2014, tá 1.200 mans skutu harur í Føroyum.

Migration patterns of the Faroe Plateau cod (Gadus morhua, L.) revealed by Data Storage tags

ABSTRACT (FAROESE): Migration routes for 23 individual cod, fitted with Data Storage Tags (DSTs), have by use of a state-space model been estimated from observations of depth and temperature. Vertical behaviour was classified into either an “at bottom” or “away from bottom” state. Cod were tagged on the spawning areas north and south west on the Faroe Plateau in 2002, 2003 and 2004. Here we present the first estimated migration routes of Faroe Plateau cod using Data Storage Tags. We related the estimated migration routes to three drivers of movements: spawning, feeding and predation and estimated daily displacement and vertical migration. The results showed that the tagged cod migrated predominantly at depths less than 200 and stayed closer than 10 m from the bottom and cod generally moved more and showed less site fidelity to spawning and feeding area than anticipated from conventional tagging (Steingrund and Mouritsen, 2009). Cod did not prefer areas with sandeel however they avoided areas with higher predation risk, here trawling is regarded as the predator. Further we found there was no significant difference in daily displacements between spawning and feeding season but daily displacements were log-normally distributed lending support to the idea that the long-term displacement is a sum of daily displacements. However daily displacements were higher in 2002 when sandeels were abundant and cod caught on longlines always stayed close to the bottom compared with cod caught by other gears that had a larger variability in the time staying off bottom.

Ymiskt um føroysku haruna og haruskjóting í Føroyum

The Faroes hare and hare hunting in the Faroe islands

ABSTRACT (FAROESE): Sjey fylgjandi mánamorgnar í november og desember mánað í 2016 var eitt fast innslag í “Góðan Morgun Føroyar”- sendingunum hjá Kringvarpinum um haru og haruskjóting í Føroyum. Fyrst var ein tekstur um føroysku haruna ella haruskjóting í Føroyum lisin. Aftaná ringdi morgunverturin til Eyðfinn Magnussen, sum er lektari í lívfrøði á Fróðskaparsetrinum, fyri at frætta tað nýggjasta um haruveiðuna, og hvussu hon hevði hilnast. Tað eru teir sjey tekstirnir, sum vórðu lisnir upp í hesum sendingunum, sum standa í hesum hefti. Tann fyrsti teksturin varð lisin 7. november, tann seinasti 19. desember.
