Survival And Reproduction

Salinity is a known factor in shaping population dynamics and community structure through direct and indirect effects on aquatic ecosystems. Salinity changes further influence food webs through competition and predation. The responses of Moina macrocopa (Cladocera) collected from Setiu Wetland lagoon (Terengganu) was evaluated through manipulative laboratory experiments to understand the ability of M. macrocopa to tolerate high salinity stress. Specifically, the fatty acid composition, growth, survival, and reproduction of this cladocerans species was examined. Sodium chloride (NaCl) as used in the treatments water with the concentration 0, 4, 6, 8, 12, and 15 salinity. Fatty acid levels were determined using Gas Chromatography and Mass Spectrophotometry (GC-MS). The results indicated that optimal conditions produced the highest fatty acid content, especially the polyunsaturated fatty acid content, such as EPA (eicosapentaenoic acid), ALA (alpha-linoleic acid), ARA (arachidonic acid), and DHA (docosahexaenoic acid). Furthermore, M. macrocopa survival was best at salinity 0, with a percentage of 98%, whereas the opposite occurred at salinity 15, with approximately 20% of viable animals surviving. Besides, M. macrocopa also showed the highest reproduction rate at salinity 0 (e.g., average initial age of reproduction, 4.33 ± 0.58 days) compared with other salinities level. Interestingly, the difference in growth at different salinities was not evident, an unusual finding when considering adverse effects such as osmoregulation pressure on the organism. Based on the results, we conclude that M. macrocopa can only tolerate salinity below salinity 8 and cannot withstand stressful environmental conditions associated with salinities above 8.

Salinity is a known factor which shapes population dynamics and community structure through direct and indirect effects towards aquatic ecosystems. The responses of Moina macrocopa (Cladocera) collected from Setiu Wetland lagoon (Terengganu) were evaluated through manipulative laboratory experiments to understand the ability of M. macrocopa to tolerate under high salinity stress. Specifically, the fatty acid composition, growth, survival and reproduction of this cladocerans species were examined. Sodium chloride (NaCl) were used in the treatments water with the concentration 0, 4, 6, 8, 12, and 15psu. Fatty acid levels were determined using Gas Chromatography and Mass Spectrophotometry (GC-MS). Results clearly indicate that normal conditions give the highest content of fatty acid, especially the polyunsaturated fatty acid content like EPA (eicosapentaenoic acid), ALA (alpha-linoleic acid), ARA (arachidonic acid) and DHA (docosahexaenoic acid). Furthermore, M. macrocopa survival also was best at 0psu, with percentage reached 98%, whereas the opposite occurred at 15psu, with approximately 9% of viable animals survived. On other aspects, M. macrocopa also showed the highest reproduction rate at 0psu (e.g. average initial age of reproduction, 4.33±0.58 days) compared with other salinities level. Interestingly, the difference in terms of growth at different salinities was unapparent, an unexpected outcome when adverse effects such as osmoregulation pressure on the organism are considered. Based on the results, we conclude that M. macrocopa can only tolerate salinity below 8psu and, is unable to withstand stressful environmental condition engendered with salinities above 8psu.

The fatty acid composition of the ethanolamine and choline phosphoglycerides was examined in the testes of Merino sheep aged 2� 5 years and lambs aged 2 weeks, and Large White crossbred pigs aged 3 years and young pigs aged 5 months. Only in the case of the choline phosphoglycerides was there a noticeable increase in the polyunsaturated fatty acid content with maturation, but the ethanolamine phosphoglycerides contained higher levels of polyunsaturated fatty acids throughout. Sheep testes were characterized by the absence of 4,7,1O,13,16-docosapentaenoic acid, but contained high levels of 4,7,1O,13,16,19-docosahexaenoic acid, particularly in the ethanolamine phosphoglycerides. This latter acid was also evident in the pig testes, but derivatives of linoleic acid, particularly arachidonic and 4,7,10,1 3, I 6-docosapentaenoic acids, were dominant.

Polyunsaturated Fatty Acid Content

Oil samples collected from three fishes namely Sting Ray (Dasyatis uarrnak), Anchovy (Setipinna taty), and Eel (Congresox talabonoides) from the Bay of Bengal were analyzed to determine their fatty acid composition with the aid of Gas Liquid Chromatography (GLC). The saturated fatty acid contents were 52.95, 45.28 and 52.29 %; and the unsaturated fatty acid contents were 43.97, 54.72 and 33.39 % in D. uarnak, S. taty and C. talabonoides respectively. The highest polyunsaturated fatty acid content was found in S. taty (13.65 %) and the lowest was in D. uarnak (8.06 %). The ψ-3 fatty acid contents were 4.58, 3.65 and 9.91 % and the ψ-6 fatty acid contents were 3.48, 10.00 and 5.50 % in D. uarnak. S. taty and C. talabonoides respectively. Two essential fatty acid linoleic acid (4.12 %) and arachidonic acid (5.32 %) contents were found higher in S. taty whereas another essential fatty acid linolenic acid (8.98 %) found higher in C. talabonoides. Another important polyunsaturated fatty acid eicosapentaenoic acid (2.12%) found higher in D. uarnak. Bangladesh J. Sci. Ind. Res. 41(1-2), 47-54, 2006

Production Traits

Crossbreeding of Holstein cattle with bulls of other breeds has garnered increasing interest with respect to efforts to improve performance traits and to decrease problems with fertility and health. Therefore, the objective of this study was to compare the effects of the fatty acid synthase (FASN) gene on milk production traits and fatty acid composition of Simmental and first-generation Holstein × Simmental crossbred cows. A total of 105 cows (72 Simmental and 33 crossbred Holstein) were genotyped using the PCR-RFLP method and their fatty acid profiles were analysed. The crossbred Holstein cows with diplotype TW/AR had significantly higher fat content and yield compared to the purebred Simmental cows of the same diplotype. The Holstein × Simmental cows with the diplotype AR/AR were also characterised by significantly lower content of C16:0 and saturated fatty acids, but higher C18:1n9, monounsaturated fatty acid and monounsaturated fatty acid/saturated fatty acid content compared to the same diplotype of the Simmental cattle. These results indicate that with accurate breeding plans, crossbreeding Holstein cows with Simmental bulls could be directed towards a more desirable fatty acid composition of milk and dairy products.
