Abstract:
... As part of research on mass-rearing the cricket Acheta domesticus (L.) as a novelty (innovative) food, four cricket diets, two prepared in the laboratory and two commercial, were compared on the basis of cost per kilogram (wet weight) of eighth instars produced. Costs were influenced by dietary ingredients, mean cricket wet weight at time of harvest, and feed/gain ratios. For the laboratory-prepar ...

... Six isonitrogenous, isocaloric diets containing commercially defatted, toasted and lightly toasted soy flours (SF) (diets 1 and 2) and four soy protein concentrates (SPC) (diets 3-6) as replacements for 40% of animal protein were fed to satiation to juvenile shrimp (Penaeus vannamei) for 10 weeks. The SPCs used in diets 3 and 5 were chemically modified products with reduced trypsin inhibitor (TI) ...

Abstract:
... Eels cultured in recirculation systems are regularly confronted with high concentrations of nitrite, a well-known toxicant for fish. In this study, the acute toxicity of nitrite to European eel, Anguilla anguilla (L.), was assessed by determination of a 96-h LC₅₀. The 96-h LC₅₀ measured for eels was 143.7 ± 2.3 gm-³ NO₂-N (mean SD), which is high compared with the LC₅₀ for other fish species. The ...

Four experimental diets, incorporating Chuni at levels of 10%, 20%, 30% and ...
... Seven purified diets were formulated and fed to seven groups of Nile tilapia, Oreochromis niloticus L., fingerlings for 12 weeks. Six of the formulated diets contained 5 or 50 mg kg-1 of ascorbic acid equivalent supplied by either L-ascorbic acid (AA), L-ascorbic-2-sulphate (AS) or L-ascorbyl-2-polyphosphate (APP). The seventh basal diet was ascorbate-free and served as the control. The results of ...

Abstract:
... Two extruded diets designed to have fat levels of 220 g kg-1 (F22) and 300 g kg-1 (F30) were fed to Atlantic salmon Salmo salar L. in two different experiments during the sea rearing period (from 0.2-0.3 kg to 3-4 kg). Each diet was fed restricted and isoenergetically at two feeding rates to fish in triplicate groups. In one of the experiments, a supplementary group of fish was fed to satiation wi ...

This study was conducted to determine the effects of feeding increasing lipid concentrations (310, 380 and 470 g kg(-1) lipid on dry weight) in diets based mainly on herring byproducts to Atlantic salmon Salmo salar. The diets were isonitrogenous, varying in dietary lipid content at the expense dietary starch. Average fish weight increased from 1.2 kg in April to 2.2-2.7 kg at the end of the feedi ...
