Abstract Twelve experimental diets were formulated to containing 35% crude protein and 429.93 Kcal gross energy 100g-1 in order to study the effects of replacement levels of dietary fish meal with soybean meal using garlic and onion on growth performance, feed utilization and whole body composition of Nile tilapia (Oreochromis niloticus) mono-sex fingerlings. Three groups of diets according to replacement levels of fish...

Most fish farmers and ornamental fish hobbyists buy the bulk of their feed from commercial manufacturers. However, small quantities of specialized feeds are often needed for experimental purposes, feeding difficult-to-maintain aquarium fishes, larval or small juvenile fishes, brood fish conditioning, or administering medication to sick fish. In particular, small ornamental fish farms with an assortment of fish require small amounts of various diets with particular ingredients. It is not cost...

Growth of shrimp was not affected by the lower cost diets containing varying amounts of poultry by product meal and soybean meal. Growth is affected when diets do not contain any marine meal. Low levels of hydrolysed feather meal require supplementation with lysine and methionine. At present farmed shrimp are the largest consumers of fishmeal within the aquaculture sector, consuming an estimated 964,000 tonnes of fishmeal in 2007....

Control of water quality is the key factor for a successful culture of aquatic animals like fish, prawn and shrimp. An open water system with sufficient good water quality may ensure successful aquaculture. However, if proper quality or sufficient quantity of water is not available, purification of water by eliminating polluting substances including toxic metabolites and growth inhibiting substances which originate mainly form fish or shrimp excretion and excessive feed is necessary. Under...

A short review on the use of potassium-diformate 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...

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 with 20...

INTRODUCTION EL-Sayed (2006) mentioned that Egypt produced 20% of the world tilapia capture and 12% of the world farmed tilapia. Bakeer (2009) cited that tilapia fish are among the ancient Egyptian fish of origin; yet, they became among the most outspreading fish species all over the world. They are cultured nowadays world wide , so their production exceeded than 2.5 million tons year 2006, and Egypt now take the 2nd position after China in the...

A shared vision for aquaculture in Asia
While modern aquaculture has been around for the past 40 years, it has not developed at the speed expected of an industry that has the enormous responsibility of creating an alternative source of seafood to the dwindling capture fisheries. One of the major contributing factors is the lack of direction, coordination and...

ABSTRACT The present work was carried out to study the effect of partial replacement of yellow corn by dried citrus pulp (as unconventional feed stuff) with and without addition of Bio-Buds (as a probiotic) in the diets of Nile tilapia fingerlings and its effect on growth performance, nutrient digestibility, and immune status. A total of 360 Nile tilapia fingerlings with an average body weight of 17±3gm were used....

The strong fuctuations of feed ingredient prices in combination with low market prices for shrimp are challenging the proftability of shrimp farming. This has accelerated a search for alternative formulations and feed additives to improve the cost effciency of feeding under various scenarios of ingredient cost and availability. Whereas most of the optimizations target resolving nutritional bottlenecks in the formula, maintaining a stable and favorable gut...

ABSTRACT
a feeding laboratorial trial in glass aquaria for 12 weeks, to replace graded levels of water hyacinth (WH) meal protein from two (polluted and not polluted) sources instead of 0, 10, 20, 30 and 40% of soybean meal protein in Nile tilapia's diet. Ten experimental diets were formulated to be isocaloric and isonitrogenous (26% crude protein) and offered daily at 2...

SUMMARY
Nile tilapia fish were divided into twelve groups, each group of fish was stocked into 3 aquaria and each contains 20 fishes. Fish of the first four groups were fed the normal basal diet, the next four groups were fed on the basal diet contaminated with 50 mg mercury/kg diet and the other four groups were fed on the same diet contaminated with 100 mg mercury/kg diet. Within each dietary mercury level, the first...

Introduction
Almost one-third of the world's fish harvest is not used for direct human consumption, but is converted into fish meal or fish oil for further application in animal feed. Therefore about 25 million tonnes of fish are handled annually and processed in ways other than fresh, frozen, smoked or canned (Balios, 2003). The supply of huge volumes of high quality fish meal is necessary to supply the rapid growing aquaculture industry, which is has been growing...

It is a well established fact in the field of aquaculture, that the use of antibiotic growth promoters as an in-feed additive for the diets of fish and shrimp may promote growth and feed conversion as well as improve survival rates. However public concerns, especially in the EU, on the development of cross-resistances to humans have led to a ban or decrease in the use of such substances worldwide. Consequently, research focussed on other additives in order to maintain performance parameter...
