The effects of feeding frequency on fish growth and feed conversion efficiency have been studied for several fish species. These studies show high variable results among and within species because regimes are age and size dependent. No single conclusion can be drawn on the influences of increasing feeding frequency (3).   A 10 week experiment was conducted to determine theeffects of feeding rate on growth, feed utilizationand body composition of the tropical bagrid catfish,Mystus h fingerlings with anaverage initial body weight of 12 g were fed apractical diet (% protein, kJ/g diet) atrates of 1, 2, , 3, , 4 or 5% of their bodyweight (BW) per day in two equal by:

The fish fed at frequencies of once daily had the highest feed conversion ratios and least feed conversion efficiencies (, %) and the ones fed twice and thrice daily had the lowest feed conversion ratios and highest feed efficiencies (, and %. feed conversion ratio: for every one broiler,a certain amount of feed is consumed. eg: broilers is feed kg of feed 1: 8 so for every one(1) broiler,eight(8)kg of feed.

Effects of feeding frequency on growth, feed conversion ratio, survival rate and water quality of white leg shrimp (Litopenaeus vannamei, Boone, ) Mazdak Aalimahmoudi, Alireza Reyshahri, Siamak Salehipour Bavarsad, Milad Maniat Abstract This study is conducted to evaluate the effect of feeding frequency on growth, feed conversion ratio andFile Size: KB.

Notably, with the increase of daily feeding frequency from three times to six and further to twelve, significant differences were found as follows: (1) the final weight, growth rate and yield of the shrimp increased; (2) the feed conversion rate decreased while the protein efficiency ratio and protein productive value increased; (3) the specific activities of protease and amylase in the stomach of the shrimp and the specific Author: Wujie Xu, Yu Xu, Haochang Su, Xiaojuan Hu, Yunna Xu, Zhuojia Li, Guoliang Wen, Yucheng Cao.

Laboratory results indicated that average feed consumption was % higher at 33 than at 29 C (Table 1), although growth was similar at both temperatures (Table 2).

Feeding frequency had no effect on food conversion ratio (FCR). Stocking density had no effect on growth, FCR and CV of final weight, but affected food consumption. The low density had the highest. () evaluated the effects of feeding time and frequency, finding that instantaneous growth rates were improved significantly with daytime feeding and switching frequency from 1 to 4 times per day.

FAO () states that shrimp natural habitats have temperatures above 20°C throughout the year so these temperatures are good for growth. As an example of this strategy, a pond with an estimated population of 30, shrimp at a given week, with an average weight gain of 1 gram/wk during the previous two weeks and an expected feed conversion ofwould require a total feed input of kg/day for the subsequent week (30, shrimp x 1g per wk x / 7 days).

The effect of four different feeding frequencies (3, 4, 5 and 6 feedings day −1) on the growth and survival of the black tiger shrimp, Penaeus monodon, and water quality was studied in an 8-week growth trial.

Effects of temperature on growth, feeding rate and feed conversion ratio (FCR) of juvenile Pacific white shrimp, Penaeus vannamei (Boone), were quantified in a series of four experiments.

In each of experiments 1 to 3, a single size class of shrimp was reared at three constant temperatures (23, 27, 30 °C) and at an ambient temperature control (mean °C).Cited by: Hand feeding of marine shrimps (whiteleg shrimp Litopenaeus vannamei and blue shrimp Penaeus stylirostris) Improving feed conversion ratio and its impact on reducing greenhouse gas emissions in aquaculture.

The rates at which feed is consumed and digested by shrimp vary with the temperature of the culture environment as well as other factors. Laboratory research and subsequent field trials by the authors examined the effects of varied water temperature on the feeding process of Pacific white shrimp, Litopenaeus vannamei.

It was calculated by total weight of total feed consumed (kg) divided by the total yield. FCR was kg feed per kg production = It implied that kg of feed is needed to produce 1 kg of shrimp body live weight. The feeding frequency can have effects on the FCR, as reported in Aalimahmoudi et : Pasicha Chaikaew, Natcha Rugkarn, Varot Pongpipatwattana, Vorapot Kanokkantapong.Eugene Beker has written: 'Effect of feeding frequency on feed conversion ratio of white tropical shrimp (Penaeus vannamei)' Asked in Turkeys Are butterball turkeys female or male?
