Fish consumption is the major dietary source of EPA and DHA, which according to rodent experiments may reduce body fat mass and prevent obesity. Only a few human studies have investigated the association between fish consumption and body-weight gain. We investigated the association between fish consumption and subsequent change in body weight. Women and men (n 344,757) participating in the Euro...
Five size groups of hatchery reared cod (2–109 g) and three size groups of wild cod (447–2213 g) were reared at a range of constant temperatures. All groups were fed to satiation, the hatchery fish on dry feed and the wild fish on capelin and shrimp. The optimal temperature for growth decreased linearly with fish weight on a log scale from 17 C for 2 g fish to 7 C for 2000 g fish. Similarly, th...
six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal science university poultry farm to compare the effects of different levels of fish oil supplementation on performance of broilers in terms of feed intake, weight gain and feed conversion and carcass characteristics. the chicks were randomly distributed following a completely randomized desig...
considering its gobiidea and feeding fish sturgeon caspian sea highest main and the need to fecundity this fish, this study was done in babolroud and tajan rivers in mazandaran. in order to conduct the study, 197 sand goby we were caught using an electros choker machine (v300-200) in the spring of 1390 ,which was the spawning season, at the tajan river (sari) and babolrood (babol). 103 fish whi...
This paper presents new low-cost systems for the automation of some fish farm operations. Particularly, computer vision is applied to noncontact fish weight estimation. Stereo vision systems with synchronised convergent cameras are employed to perform fish 3-D segmentation in tanks and sea cages. Several pre-processing algorithms are applied to compensate illumination local variations. The appr...
In this study, a feeding trial was conducted to examine the potential of replacing fish meal with brewers yeast in practical diet of goldfish (Carassius auratus). Five isoproteic (37% CP) and isocaloric (3350 kcal/kg) diets were formulated to contain graded levels of brewers yeast. Fish meal protein was replaced by 0%, 15%, 25%, 35%, and 45% of yeast. Each diet was randomly allocated to triplic...

Little is known about the effects of the interaction of growth hormone (GH) with 17 alpha-methyltestosterone (17-MT) during fish growth. We evaluated this in the present study to assess the effect on fish growth. Fish in two batches of juvenile tilapia (Oreochromis niloticus) (approximately 5.0cm in length) were randomly assigned in triplicate to three treatments and a control group, distribute...
BACKGROUND Overweight and obesity are increasing in young adults. However, moderate energy restriction aimed at lowering body weight may promote bone turnover and bone loss. Inclusion of fish or fish oils in a weight-loss diet may attenuate these adverse skeletal effects. OBJECTIVE We examined the effects of incorporating fish or fish oil into an energy-restricted diet on bone turnover marker...
