The nutritional condition of turbot larvae (Scophthalmus maximus) was assessed by a multivariate analysis with DNA, RNA, and protein content as input variables. Special attention was given to the time that feeding began and to the timing and duration of starvation. The combination of the principal components analysis and the stepwise discriminant analysis, both techniques of multivariate analys...

Competent larvae of the serpulid polychaete, Hydroides elegans (Haswell), were induced to 24 metamorphose by either 10 M 3-isobutyl 1-methylxanthine (IBMX), adult homogenate, or 30 1 1 mM excess K . Treatment with excess K had adverse effects (P , 0.05) on juvenile growth while IBMX and adult homogenate had no detectable effects (P . 0.1). Metamorphosis was triggered using IBMX in subsequent st...

Crude protein, fat, water, ash, dry matter and essential amino and fatty acids were analyzed from freshly collected Chironomus plumosus larvae in order to evaluate their suitability as a component for farmed fish diet. The analyses were performed in intact living organisms and in the dry matter. Essential amino acids were determined by LKB 4101 automatic analyzer, while fatty acids were determi...

Effects of using n-3 HUFA-enriched Artemia and non-enriched Artemia as the starter food for growth and survival of rainbow trout larvae compared to commercial concentrated food were investigated in this study. The larvae with average weight of 92.9 mg were fed for 20 days with four food treatments included of commercial concentrated food, newly hatched Artemia, enriched Artemia, and mixture of ...

Immunostimulants are one of the important ways to prevent diseases. The vaccination and immune system stimulator and their combination can increase the ability of vaccines in prevention of diseases and improved indexes of growth and survival rates in shrimps. In this research, the separate and simultaneous effects of Ergosan and Vibromax vaccine on the growth factors such as total length and in...

Waste from apple juice and cider industries (pomace) compares poorly against spent grains other relatively high-nutrient wastes as a substrate for bioconversion by the black soldier fly (BSF: Hermetia illucens). However, global pomace production exceeds 24 million tonnes annually novel management approaches are required to reduce waste landfill. We examined effects of BSF inoculation densities ...

Objective: In this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) Chironomid larvae were examined. Methods: For this purpose, 2.5 grams of food per Coconut considered in the period, with three replicates and Chironomid larvae during the period of 15 days in plastic pans were kept in nut...

Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential trace element and both under and over supply of I can inhibit the production of the I containing thyroid hormones. It is unknown whether marine fish larvae require copepod l...
