the purpose of this experiment was to evaluate the effects of salinity on growth parameters and intestine morphology of the caspian white fish. experiment were used with four treatments include,(freshwater (0ppt), brackish water (5ppt), abrupt transition of fish to the salt water 10ppt: )the fish were transferred from fresh water to salt water immediately) and gradual transition of fish to the ...

—Channel catfish Ictalurus punctatus do not feed well at low temperatures. It is generally thought that a diet containing fish meal enhances feed palatability at low temperatures since fish meal is highly palatable to fish. There is a lack of information on the effects of fish meal levels on the growth performance of channel catfish reared at low temperatures. Therefore, a study was conducted i...

This study evaluated the suitability of canola oil as a source of supplemental dietary lipid for rainbow trout. Triplicate groups of the 30 fingerlings held under identical culture conditions were fed twice daily by iso-nitrogenous, iso-calorific and iso-lipidic diets for eight weeks. Experimental diets consisted of 30.3% protein, 18.7 kJg-1 energy and 16.7% lipid from fish oil (FO), canola oil...

1. The rate of utilization (k) of labelled thyroxine increased when energy intake, given as standard pig meal, was doubled from 20 to 40 g/kg body-weight per d. When the bulk of food was increased, but not its energy content, the value of k did not change. Ambient temperature was constant throughout the experiment. 2. Groups of pigs were given pig meal at 20 g/kg body-weight, 40 g/kg body-weigh...

Ž . A feeding trial was designed to evaluate the influence of partial replacement of fish meal FM protein for soy-derived protein in large rainbow trout fed practical, high-energy diets with and Ž without supplemental phytase. A 2=2 factorial arrangement with two soy levels 0% and 69.4% . Ž y1. of the dietary protein from soybeans and two phytase levels 0 and 1200 U kg was used. Soy Ž . Ž . pro...

shellfish and anisakis. Prick-by-prick test showed positive reaction to raw angler fish, and negative to cooked angler fish. The handling tests were negative to cooked angler fish, and positive to raw angler fish with immediate development of urticaria in areas of contact. Total serum IgE was 216 kU/L. Fish extracts (angler fish and hake) were extracted in phosphate buffered saline (PBS) by mix...

Two otherwise healthy middle-aged males presented with persistent abdominal and lower- back pain, progressive weakness, paraesthesias, fatigue and weight loss over 8-12 months. Extensive work-up failed to localize organ pathology. Both men, strongly aware of the nutritional benefits of fish had a diet dedicated of canned and fresh fish. Raised blood mercury levels confirmed clinical suspicion a...

The relationship of gonad weight and liver weight with body weight of six fish species viz; Catla catla, Labeo rohita, Cirrhina mrigala, Hypophthlamichthys molitrix, Ctenopharyngodon idella and Cyprinus carpio under the influence of artificial feed, broiler manure, buffalo manure, N:P:K (25:25:0) and a control pond were examined after a rearing period of one year. The positive relationship betw...

This experiment was conducted to characterize the effect of fasting versus satiety feeding on plasma concentrations of GH, IGF-I, and cortisol over a nychthemeron. Channel catfish fingerlings were acclimated for two weeks under a 12L:12D photoperiod, then fed or fasted for 21 d. On day 21, blood samples were collected every 2 h for 24 h. Weight of fed fish increased an average of 66.2% and fast...
