An approach to estimate the daily ration of cod during intensive feeding based on 24 hour fishery
Ajiad, Adnan Mosa; Korsbrekke, Knut (PINRO-IMR Symposium, Conference object, 1992)A model descnbing gashic evacuation developed by dos Santos (1990) using a modified version of the power exponential model for stomach evacuation is applied to the Northeast Arctic cod stomachs collected during 24 hour ... -
Assessing growth of Northeast Arctic cod by a bioenergetics model
Ajiad, Adnan Mosa (ICES CM Documents;1996/G:16, Working paper, 1996)This paper represents an attempt to elucidate how fish body size differences and metabolic costs alter the relationship between growth and consumption using a bioenergetics model. The results show that the daily growth ... -
Can a bioenergetics model explain growth of the northeast Arctic cod?
Smedstad, Odd M.; Ajiad, Adnan Mosa; Korsbrekke, Knut (ICES CM Documents;1994/G:7, Working paper, 1994)For the period 1984 to 1991, the individual maximum daily consumption in calories (cmax) based on 33000 cod stomach samples is given by the power equation: Cmax = 68.84 · W ^0,934 where W represents the total fish ... -
The daily feeding dynamics in various length groups of the Barents Sea capelin
Ajiad, Adnan Mosa; Pushchaeva, T. Ya. (PINRO-IMR Symposium, Conference object, 1992)A total of 692 capelin stomachs collected in the Goose Bank area in August 1989 by 24 hour fishery were analyzed by 3 cm capelin length groups. The nwnber of prey categories consumed by the Barents Sea capelin showed a ... -
Daily rations of cod from the Barents Sea
Dolgov, Andrey V.; Yaragina, Natalia A.; Ajiad, Adnan Mosa; Mehl, Sigbjørn; Bogstad, Bjarte (PINRO-IMR Symposium, Conference object, 1992)Diurnal feeding rhythms and daily diets of the North-East Arctic cod were investigated based on data obtained at several stations made in the summer of 1988-1989. A well-pronounced feeding rhythmicity was recorded under ... -
Demonstration of maternal effects of Atlantic cod: Combining the use of unique mesocosm and novel molecular techniques – A new EU-project
Svåsand, Terje; Ajiad, Adnan Mosa; Dahle, Geir; Jakobsen, Tore; Kjesbu, Olav Sigurd; Moksness, Erlend; Otterå, Håkon; Solemdal, Per; Thorsen, Anders (ICES CM documents, Working paper, 2000)One of the effects of fishing is a reduction in average age and size in exploited fish stocks, leading to an increasing proportion of recruit spawners in the stock. Current management practice assumes equal viability of ... -
Diet of polar cod, Boreogadus saida, in the Barents Sea related to fish size and geographical distribution
Ajiad, Adnan Mosa; Gjøsæter, Harald (ICES CM Documents;1990/G:48, Working paper, 1990)Polar cod stomachs collected during autumn of 1986-1988 in the Barents Sea were analysed. The results indicated that polar cod is an opportunistic feeder, and that the observed changes in feeding pattern from one region ... -
Growth of Polar cod (Boreogadus saida) in the Barents Sea
Gjøsæter, Harald; Ajiad, Adnan Mosa (ICES CM Documents;1990/G:47, Working paper, 1990)Observed length-at-age, and backcalculated lengths based on otolith measurements, from samples of polar cod collected in the Barents Sea in autumn of 1987 to 1989, were analysed. An increase in individual length growth ... -
The daily feeding dynamics in various lenght groups of the Barents Sea capelin during the feeding period
Ajiad, Adnan Mosa; Pushchaeva, T. Ya. (ICES CM Documents;1991/H:16, Working paper, 1991)A total of 700 capelin stomachs collected during the feeding period in August 1989 by 24-h fishery were analyzed for each 3-cm length groups. The number of prey categories consumed by the Barents sea capelin showed a ... -
Trophic relationships and feeding-dependent growth in the North-East Arctic cod
Ajiad, Adnan Mosa; Mehl, Sigbjørn; Korsbrekke, Knut; Dolgov, Andrey V.; Korzhev, V. A.; Tretyak, Viktor; Yaragina, Natalia A. (PINRO-IMR Symposium, Conference object, 1992) -
Variabilities in stomach contents of cod, collected by demersal and pelagic trawl in the southern part of the Barents Sea
Ajiad, Adnan Mosa (ICES CM Documents;1990/G:3, Working paper, 1990)Samples of Northeast Arctic cod stomachs were collected separately on demersal and pelagic stations at the same date in February 1986 and were analysed for length group 30-40cm. The results indicate that the mean value ...
