Optimum daily ration for Eurasian perch Perca fluviatilis L. reared at its optimum growing temperature

Linking fatty acids in the diet and tissues to quality of larval southern flounder (Paralichthys lethostigma)

“…For red sea bream (Pagrus major), feeding guidelines suggest 11% at 0.3 g WW, 9% at 0.9 g, and 5.3 -6.5% WW d when they reach 8 g WW (Daniels and Gallagher, 2002). R opt for freshwater Eurasian perch (Perca fluviatilis) between 0.22 -18.9 g WW was expressed as R opt = 8.22•WW -0.32 (Fiogbé and Kestemont, 2003), which is lower than our findings and a stronger effect of size.…”

Optimum ration level for better growth, conversion efficiencies and body composition of fingerling Heteropneustes fossilis (Bloch)

“…Since water temperature influences body temperature, the growth rate and metabolic rate of fish reared at different temperatures are expected to have different values for optimum feeding rate (Jobling 1983;Borghetti and Canzi 1993;Xie et al 1997). Studies have shown that ration level also changes with the temperature, size and/or age of the fish and with the experimental conditions, such as stocking rate, feeding regimes or water quality (Brett 1979;Paul et al 1994;Haroon and Pittman 1997;Xie et al 1997;Webster et al 2002;Fiogbe and Kestemont 2003;Bailey and Alanara 2006). …”

A bioenergetic model to estimate feed requirement of gibel carp, Carassius auratus gibelio

“…Empirical approaches and growth models had been usually used to determine the optimal ration level and guide the feeding in practice (Shearer, 1995;Xie et al, 1997a;Cui et al, 1997;Fiogbé and Kestemont, 2003). In some studies, growth trials were conducted under a series of ration levels from starvation to satiation and the optimal ration level was estimated based on the maximum diet conversion efficiency (Xie et al, 1997a;Zhu et al, 2000), and the optimal feeding ration was also considered as the minimal diet consumption to maintain the maximum growth (Stickney, 1979;Piper et al, 1982;Charles et al, 1984;Hung and Lutes, 1987;Hung et al, 1989;Cui and Hung, 1995).…”
