Protein-Sparing Ability of Carbohydrates from Different Sources in Diets for Fry of Stinging Catfish Heteropneustes fossilis

Abstract

The experiments were carried out to evaluate the protein-sparing effect in Heteropneustes fossilis fry (0.751 ± 0.01 g) fed for 90 days with six isocaloric diets containing 45, 40 or 35% of casein-protein and 25, 30 or 35% of glucose/dextrin, combined

Effects of light and artificial fish shelter (PVC pipe) on some phenotypic traits of stinging catfish (Heteropneustes fossilisBloch, 1794)

“…Although this species has enormous aquaculture potential which could be easily grown in ponds and small ditches, its commercial culture has not yet been well flourished in Bangladesh due to lack of appropriate culture technique. However, some studies have already been carried out about its growth and production (Kamruzzaman, Rahman, Rabbane, Ahmed, & Mustafa, ; Khan et al, ; Kohinoor et al, ), stocking density (Narejo, Salam, Sabur, & Rahmatullah, ; Kohinoor et al, ), culture technique (Khan et al, ; Rahman, Monir, & Mou, ) and utilization of food (Ali, Hoq, Khan, & Zaher, ; Rahman, Salam, Ahsan, Hossain, & Hossain, ). Considering the lack of information about the effects of light and artificial habitat on larval rearing, the present experiment has been designed to ascertain whether the light and artificial shelter separately or interactively can affect the growth and other phenotypic traits of Asian stinging catfish ( H. fossilis ) larvae reared in a controlled laboratory condition, which will help to improve the culture of this threatened species in this region.…”

Haematological and Biochemical Responses of Juvenile Malabar Blood Snapper (Lutjanus malabaricus Bloch & Schneider, 1801) Exposed to Different Rearing Temperatures and Diets

“…Temperature of aquatic environment is important for ensuring survival, distribution and normal metabolism of fish, failure to adapt to temperature fluctuations is generally ascribed to the inability of fish to respond physiologically with resultant mortality, which is related to changes in the metabolic pathways (Forghally et al 1973). The result is a collapse in osmoregulatory functions during temperature extremes (Gubbins et al 2000;Rahman et al 2017). Fish can adapt to the changed temperature of its habitat to a certain extent, but when a particular temperature exceeds the threshold value, thermal stress occurs.…”
