Comparative study of body composition of four fish species in relation to pond depth

Abstract

Fish specimen of Labeo rohita, Cirrhinus mrigala, Hypophthalmicthys molitrix and Catla catla were sampled from three ponds of different depths (152 cm, 122 cm and 76 cm) to compare the body composition of these species in relation to pond depth. There was significant (P < 0.001) effect of pond depth on water, ash, organic, fat and protein contents (all % wet and dry body weight). It was observed that pond depth has significant effect (P < 0.01) on condition factor in pond B (122 cm depth) and no effect in pond A and C. Maximum mean values of body composition were observed in Labeo rohita in all the three ponds. Present study demonstrates that fish cultured in ponds of different depths have different values of protein which can help guide the farmers to select best pond depths to produce protein rich fish.

Effect of different precooking methods on chemical composition and lipid damage of silver carp (Hypophthalmichthys molitrix) muscle

“…The proximate composition of raw fillets is comparable to that of observed by Siddaiah et al. (2001) and Ali et al. (2005) for silver carp.…”

“…The changes in moisture, ash, protein and fat content of samples after precooking processes are shown in Table 1. The proximate composition of raw fillets is comparable to that of observed by Siddaiah et al (2001) and Ali et al (2005) for silver carp.…”

Effects of salinity on sublethal toxicity of atrazine to mummichog (Fundulus heteroclitus) larvae

“…Proteins in larvae (% dry mass) were calculated. Residual mass [defined as dry body mass-(lipid-protein content)] was also calculated and expressed as percentage of dry mass (Ali et al, 2006).…”

Using soil from pellets of White StorksCiconia ciconiato assess the number of earthworms (Lumbricidae) consumed as primary and secondary prey

“…This was taken as 25% for fish (Ali et al . , Nurnadia et al . ), 27% for reptiles (Vitt ), 41% for birds (Shoffner & Brittingham ) and 32% for mammals (Baker et al .…”

“…The wet weight of vertebrate prey (for small mammals based on data of their weight collected in the Mammal Research Institute and other vertebrates from literature sources) was converted to dry mass by multiplying by the estimated percentage dry mass. This was taken as 25% for fish (Ali et al 2006, Nurnadia et al 2011, 27% for reptiles (Vitt 1978), 41% for birds (Shoffner & Brittingham 2013) and 32% for mammals (Baker et al 1993).…”
