In order to elucidate the effects of feeding, segregation and refuges on growth freshwater catfish, Wallago attu, post-hatch larvae were fed with live zooplankton alone (moina) or combination between moina one following food: commercial pellets minced trash fish cow liver. For impacts W. these treatments applied seperately in refuges. The results indicated that final total length – (TLe: 54.0 ±...

The roles of some abiotic factors in controlling the hatching rates of Moina micrura ephippial eggs were investigated. Determination of optimum hatching conditions would be important in developing the use of this species as a food for fish larvae in aquaculture. Ephippia were exposed to different treatments in the laboratory, and monitored for hatching over a period of seven days. Optimum hatch...

there are various factors affecting the fighting fish larval survival including nutrition, substrate, water quality, pathogen and stress. experiments were conducted to study the effect of substrate and live feed on larval survival of fighting fish fry. nine small glass aquaria (60 cm × 30 cm × 30 cm) were used as breeding tanks. equal pieces (80 cm2) of rigifoam (t1), polythene (t2) and banana ...

The present study was conducted to assess the effects of different feed regimes for nursing knife fish (Notopterus notopterus) larvae up 35 days. Larvae were reared in 50 L tank with Moina, Tubifex worm, and commercial powder substituted culture Feeding worms during found best growth rate survival fish. result obtained when fed 0-5 days 6-20 tubifex 21–35-day weight gain 0.31 g, length 2.36 cm,...

The aim of the present study is to find out if occurrence zooplankton with incubated eggs common carp (Cyprinus carpio L.) could increase fungal infection causing saprolegniasis in main fish hatchery Iraq during artificial propagation from April June 2009. Four treatments were used, highest hatching rate was 85.8 % treatment no. 2 which filtered water used incubate and lowest 21 negative contro...

Abstract Moina is a group of tiny shrimp belonging to the class Crustacea and sub-order Cladocera, which can reproduce grow quickly in various food sources be cultivated under low oxygen high ammonium content. Utilization as natural not maximized because it still constrained by quality management availability cultivation media affects its productivity. One efforts make available sustainably pro...
