Growth responses and fatty acid composition of juvenile prawns (Macrobrachium rosenbergii) fed a prepared ration augmented with shrimp head oil

Fatty acid profiling reveals a trophic link between mangrove leaf litter biofilms and the post-larvae of giant tiger shrimp Penaeus monodon

“…This could imply possible mobilization of FA valuable carbon sources in biofilm. Lipids play a major role in the physiological performance of shrimp by providing energy and enhancing growth and reproduction (Sandifer & Joseph 1976, Lavens & Sorgeloos 2000. In addition, our SIMPER results showed that DHA contributed most to the close resemblance between the shrimps fed with compound food and those fed with biofilm food.…”

“…The contribution of EFAs from decomposing mangrove leaf litter to mangrove estuarine and integrated shrimp culture ecosystems may be largely limited by the reduced palatability of the mangrove leaf litter caused by the presence of tannins which may deter grazers (Scalbert 1991). However, the growth of the periphytic biofilm can buffer or rather condition the effect of such chemical deterrents by mobilizing the counteractive positive effects of EFAs to the physiology of consumers (Sandifer & Joseph 1976, Lavens & Sorgeloos 2000. EFAs are found in the micro-algae and epifauna (Parrish 2009), which are among the major constituents of the periphytic biofilm (Gatune et al 2012(Gatune et al , 2014.…”

“…Therefore an exogenous source of HUFAs is necessary as part of the essential FAs (EFAs). The ω-6 FAs, such as linoleic (18:2ω6) and arachidonic acid (ARA,20:4ω6), are essential as energy sources, while ω-3 FAs, such as linolenic acid (18:3ω3) and HUFAs, are utilized for the biosynthesis of longer-chain PUFAs in tissue in corporation (Sandifer & Joseph 1976). During the de composition of mangrove leaf litter, FAs are changed either in terms of abundance (Mfilinge et al 2005) or biochemical state, which could lead to increases in unsaturated FAs and bacterial FAs (Mfilinge et al 2003).…”

Biochemical changes associated with embryonic and larval development in the American lobster Homarus americanus Milne Edwards

“…It is suggested that either 20:5 or 22:6 or both fatty acids were responsible. Other experiments have also shown that dietary sources of 20:5 or 22:6 were beneficial or might even be essential to decapod crustaceans (Castell and Covey, 1976;Sandifer and Joseph, 1976;Guary et a1., 1976;Kanazawa and Teshima, 1977;Kanazawa et al, 1978Kanazawa et al, , 1979a. It is possible, however, that other nutrients in cod liver The moderate differences in fatty acid levels between the control and CLO supplement fed populations also indicate that the CLO supplement was probably just barely adequate in supplying the necessary extra amounts of 20:5 and 22:6.…”

Crescimento em viveiro de cultivo do camarão canela (Macrobrachium Amazonicum) (Decapoda, Palaemonidae)

“…Nestes estudos tem sido levada em conta a influência de vários fatores, como a alimentação (Balazs et ai., 1974;Manik, 1976;Sandifer & Joseph, 1976;Willis, Hagood & Ellason, 1976;Coelho, Ramos-Porto & Cordeiro, 1978a, b), a densidade de população (Sandifer & Smith, 1975;Willis, Hagood & Ellason, 1976;Willis & Berrigan , 1977), as condições da água tais como: temperatura, salinidade e teor de oxigênio (Perdue & Nakamura, 1976;Coelho et ai., 1978;Farmanfarmaian & Moore, 1978 (Coelho el ai. , 1978) e M .…”
