The effect of salinity (0, lO and 20%o, water temperature 28 ± l oC) on food consumption and growth of juvenile Nile tilapia, Oreochromis niloticus L. (9.94 ± 0.15 g) were investigated by feeding group of 20 fish at 2% body weight day·• Individual food consumption was measured using X-radiography. There were no significant differences in growth or white muscle protein concenrrarions among group...

Consumption of fish has been encouraged recently because it may prevent mortality due to heart disease. Fish contains methylamines, which are precursors of N-nitrosamines. Nitrosamines can act as potent carcinogens in a wide variety of animal species, and there is no reason to assume that humans are resistant. Human subjects (n = 5) ingested a diet of known methylamine content for 2 days. On Da...

BACKGROUND Fish and meat intake may affect gestational weight gain, body composition and serum fatty acids. We aimed to determine whether a longitudinal dietary intervention during pregnancy could increase fish intake, affect serum phospholipid fatty acids, gestational weight gain and body composition changes during pregnancy in women of normal weight participating in the Pregnancy Obesity Nutr...

compensatory growth response and body composition of male sailfin molly, poecilia latipinna subjected to short-term starvation and subsequent feeding were studied for 54 days. four feeding schedules were used in this study: c, control (were fed to apparent satiation throughout the experiment); t1, treatment 1 (3 days starvation and 6 days refeeding); t2, treatment 2 (6 days starvation and 12 da...

background: vitamins are considered an essential part in diet of aquatic animals. objectives: this study was carried out to assay the effect of different levels of vitamin e on growth performance, carcass compositions and blood parameters of common carp fingerlings (cyprinus carpio). methods: total number of 96 common carp fingerlings weighing 15.49 ± 3.64 g were randomly distributed into 12 fi...

The studied in channel catfish Ictalurus punctatus fingerlings held in 80-L aquaria. Nonabraded fish were challenged by immersion on day 0. Thirty 80-L tanks were randomly assigned in equal numbers to two treatment groups, one in which fish were fed a commercial diet without florfenicol (unmedicated feed) and one in which they were fed a diet containing 10 mg of florfenicol/kg of body weight (m...

this study was carried out within 7 months in dikjeh area, golestan province, iran. during that time the relationship between water salinity and ec with hematocrite, blood serum ionic parameters, growth, survival and stress indices in common carp (cyprinus carpio) were investigated. hematocrite as stress index was measured by hemocitometry standard method using microhematocrite reader. fish bio...

Specimens of Gangetic whiting, S. panijus, were collected from the Meghna estuary to estimate the fecundity and Gonadosomatic Index (GSI) during April-September, 2011. The morphometric and meristic features of the fish were measured. The co-efficient of correlations between total length and head length with other body measurements were significant (P<0.01). The logarithmic length-weight relatio...

Sardinella sindensis is one of the dominant small pelagic fish of Karachi coast of Pakistan. Investigation on fecundity of sind sardinella was studied from January 2001 to April 2002. A total of 37 ovaries were examined of stages IV-VI (when not running). Mean fecundity ranged from 47521 to 110876 eggs. Log-log relationship between fecundity with total body-length, fish-weight & ovary weight we...
