—A 6-wk feeding study was conducted to determine the effect of feeding frequency on growth rate of juvenile Norris and NWAC103 channel catfish, Ictalurus punctatus, reared under laboratory conditions. Four replicate groups of Norris and NWAC103 catfish (average weight of 4.0 6 0.2 g/fish, SEM) were fed to visual satiety at different feeding frequencies (one, two, or three times daily). The perc...

Background and aims: To evaluate the effect of fish oil supplementation on pregnancy outcomes in mother and newborn. Method: This randomized, triple-blinded placebo-controlled trial was conducted on 150 pregnant women aged 18–35 from February 2014 to April 2015 in Tabriz, Iran. Participants assigned to receive either 1000 mg fish oil supplements containing 180 mg eicosapentaenoic acid and 120 m...

Gizzard shad (Dorosoma cepedianum) were collected from four locations in western Lake Erie during summer, 1982. The nutritional quality of foods ingested by these fish was examined. Small (<60 mm standard length), age 0 fish consumed mostly zooplankton with high organic (>80% of dry weight) and nitrogen (>6% of dry weight) contents. The phytoplankton and detritus diets of larger, age 0 and adul...

Length-weight and length-length relationships are presented for four fish species from the estuaries of south Johore, Peninsular Malaysia. The values of the exponent b in the length-weight relationships (LWRs) W= aL b ranged from 2.97 to 3.44 and length-length relationships (LLRs) TL= aSL b ranged from 0.87 to 0.95. The application of these regressions should be limited to the observed length r...

The purpose of this study was to determine the most optimal density komet fish (C. Auratus) fry in rearing with a recirculation system. This used completely randomized design (RAL) 4 treatments and 3 replications where were : A stocking 1 fish/L, B C: 5 fish/L D 7 fish/L. Parameters observed survival rate, absolute weight growth (PBM), length (PPM), blood glucose. results showed that average ra...

during this study from december 2009 to november 2011, 363deep flounder fish were caught and their weight and length were measured. the caught fish included 18 males, 200 females and 155 immature fishes. the mean, maximum and minimum total lengths were 264 ± 57 (mean ± sd), 415 mm and 115 mm respectively. the mean, maximum, and minimum total weights for this species were 238 ± 150 g, 827 g and ...

previous studies have indicated that fish oil intake wi1l improve semen quality in some mammals and birds. the aim of this study was to investigate the effect of dietary fish oil on reproductive performance in ram. eight zandi rams were divided into two groups and fed either a control diet or a supplemented diet with fish oil. both of the diets were isocaloric and isonitrogenous and formulated ...

introduction: nowadays, the healthiness and high quality as well as quantity of aquatic are of great importance and the role of diet components is well recognized (20). fish needs energy and nutrients in order to achieve desirable level of growth and development and reproduction (11). in recent years application of immune system stimuli has been widely adopted in order to enhance the immune sys...
