The role of microalgae in aquaculture: situation and trends ArchiMer
Muller-feuga, Arnaud.
Algae are utilized diversely in aquaculture, but their main applications are related to nutrition. They are used in toto, as a sole component or as a food additive to supply basic nutrients, color the flesh of salmonids or for other biological activities. The need for nutritional sources safer than traditional animal products has renewed interest in plants in general and algae in particular. This report deals principally with the nutritional role of microalgae in aquaculture.The larvae of molluscs, echinoderms and crustaceans as well as the live prey of some fish larvae feed on microalgae. Though attempts have been made to substitute inert particles for these micro-organisms which are difficult to produce, concentrate and store, only shrimp and live prey...

This study evaluated the effects of hatching in low performance broiler chicks before industrial production on survival rate and productive performance. Twelve houses of 15,000 birds each, day-old chicks (Ross 308) were assigned to randomized complete block design (RCBD) in a 2×2 factorial arrangement with two factors. Each factor was divided into 3 blocks. Factor A was types of brood (normal and hatchery brood) and factor B was sex (male and female). The results showed that no interaction between survival rate and growth performance in broiler chickens (P>0.05). However, hatchery brood slightly decreased in mortality rate of chickens during transportation and increased survival rate, average daily gain (ADG), average daily feed intake (ADFI), feed...
