Abstract:- The present study was carried out to evaluate the comparative effects of alternative growth promoters as REE and some traditional growth promoters as Bactocell "probiotic" and oxytetracycline "antibiotics" on growth performance, body composition, feed efficiency and nutrient digestibility of Tilapia Nilotica fingerlings. A total of 200 fish were nearly of the same size with mean body weight (34.48 gm), the fish were divided into equal 4...

ABSTRACT A field study was conducted on brood stock Nile tilapia to increase the reproduction performance. Both sexes were individually stocked into habas (enclosures) in an earthen pond and fed for 19 days on a basal diet supplemented with different additives at graded levels of each ( 0.0, 0.5, 1.0 and 2.0 g Therigon ® (T 1 -T 4 ; T 1 as a control treatment respectively );...

ABSTRACT
The aim of this study was to evaluate the effect of some unconventional diets on diets composition, growth performance, blood picture, whole fish and fish muscles composition, and feed utilization by Nile tilapia fingerlings (7-8g). Twenty six glass aquaria (60 x 35 x 40 cm) connected with electric pumps for water aeration were...

Abstract
An experiment was conducted to evaluate the effect of two different commercial feed additives on growth performance of monosex Nile tilapia fingerlings. Seven treatments were applied, three levels of Biogen ® (0.1, 0.2 and 0.3%) and Pronifer ® (0.1, 0.2 and 0.3%) in addition to control. The tested diets were applied in 21 fiberglass tanks each was stocked randomly...

ANNE KRUGER, PRESENTER: Aquaculture might seem like a simple solution to the global decline in wild fish stocks. But the problem is the most popular farmed fish species need to eat fish or at least fish oil to get the healthy ingredients which make them such an important part of the human diet.
Right now there's a global search for new sustainable alternatives and some of the most promising research is being done right here in Australia.

ABSTRACT
The present study was carried out in a 24 earthen pond system (one feddan each, three replicates for each treatment) to investigate the effect of feed, feed plus fertilization (organic± inorganic fertilizer), improved (fertilized with organic± inorganic± supplementary feeding with rice bran) and poor nutrient inputs (fertilized with poultry manure, PM) on the...

SUMMARY
The protein requirements of fingerlings grey mullet, Mugil cephalus with an initial body weight of 5.5 g on the average, were studied by using four diets containing 32, 36, 40 and 44% crude protein, and fed for 90 days. The best growth performance was obtained with 36% crude protein and carbohydrate 35%, followed by the diets containing 40, 44 and 32% crude protein respectively. Protein efficiency ratio was decreased with increasing dietary protein...

Abstract
This research was conducted to study the effect of lipid levels on growth performance of fingerlings Sea bass. Sea bass ( Dicentrarchus labrax ) fingerlings with an average body weight 1.2±.0.2g were fed one of four compound diets containing 50% crude protein with different level of lipids,...

The Vietnamese government is pushing to reform and modernize its meat-processing industry. The push to build more modern slaughter houses, offer investment incentives to private operators, and impose tough laws and standards indicates growing demand for modern meat processing technology. ILDEX Vietnam 2010 is expanding its meat-processing profile to satisfy this demand.

Abstract A preliminary study (120 days) was conducted on African catfish (initial body weight 90 g) to evaluate the beneficial effects of a new patent local probiotic (T-Protphyt 2000) when added to their diet (25% crude protein) at graded levels (0, 1, 2, and 3 g/Kg diet). The diet containing 1 g/Kg (T 2 ) reflected the best growth and feed utilization parameters. Increasing the...

Acid preservation of fish and fish viscera to produce fish silage is common practice. The final product has been widely used in fish feed and as a feed component for fur animals. In many European countries it is a commonly used method of preserving fish-by-products, using formic acid or its salts to keep the fish silage stable. However, due to regulatory restriction and the limited tolerance to formic acid in fur animals such as mink and foxes, the accepted practice of preparing fish silage...

Routine use of antibiotics as growth promoters is a matter of debate in the animal farming industry. The EU has banned all antibiotic growth promoters (AGP) from livestock production with effect of January 2006. Public opinion and regulation authorities in most of the export countries focusing now on the misuse of antibiotics in aquaculture and public attention have shifted towards production methods. Therefore, alternatives to AGP are worldwide sought in a variety of forms. Acidifiers...

Introduction
Routine use of antibiotics as growth promoters is a matter of debate in the animal farming industry. The use of low levels of these antibiotics in animal feeds possesses the possibility to transfer bacterial immunity to species pathogenic in animals and humans (Liem, 2004). The EU has banned all antibiotic growth promoters (AGP) from livestock production with effect of January 2006. Public opinion and regulation authorities in most of the export...

Recording feed intake To be able to select directly for feed effi ciency, feed intake of individual fi sh should be recorded. Until recently, diffi culties in measuring individual feed intake on a large scale have prevented accurate genetic evaluation of feed utilization traits in farmed fish. To solve the recording challenges, we have applied the X-ray method to measure feed intake and feed effi ciency of thousands of individuals in pedigreed populations of...

In trout farming, the amount and suitability of feed used determines the profitability of production. Trout and other salmonids can efficiently digest foods that contain primarily protein (mostly from fish), and can obtain some of their energy from fats and, to a lesser extent, from carbohydrates. Fry and fingerling trout require a higher protein and energy content in their diets than larger fish. Fry and fingerling feed should contain approximately 50 percent protein and 15 to 20 percent...

Farmed cod and halibut larvae require live feed the first days after hatching before they can eat dry feed. This is a vulnerable period for the larvae. Studies carried out at the National Institute of Nutrition and Seafood Research (NIFES) show a higher survival rate among cod larvae when they are fed partially digested proteins.
In a feeding trial carried out by NIFES, cod larvae were given dry feed with varying levels of partially digested proteins i.e. hydrolysed...

Freshwater fish farmers in Vadodara (India) are increasingly using urea and other chemical fertilisers to boost production. With better subsidies for procuring seeds, the farmers use fertilisers during the nursing period to better the yield.
The farmers are facing stiff competition from their counterparts in Andhra Pradesh. They said fish and prawns from the state are unfit for consumption.
"In Andhra, they nurse the fish and prawn seeds with pig stock and beef, which we...

Toxaphene is a pesticide that may be present in fish meal and fish oil. Along with several other research institutions, the National Institute of Nutrition and Seafood Research (NIFES) has initiated a project to examine how toxaphene in fish feed affects fish health and food safety.
Fish are sensitive to waterborne toxaphene, but relatively little is known about the way fish respond to toxaphene in fish feed. Through a 3-year project entitled...

Salmon is getting a menu makeover.
Scientists at Nutreco Holding NV, the world's largest maker of fish feed, spent a decade perfecting a salmon diet, replacing fish meal from wild catch such as Peruvian anchovies with a mix of soybeans, rapeseed and ground-up chicken. The company is working to phase out the chicken, making the meal all-vegetarian, said Alex Obach, managing director at Nutreco's research unit.
"Fish have an amazing capacity to adapt very quickly to a new...
