the effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. there was no significant difference in final weight (m...

VectoBac DT, a tablet formulation of Bacillus thuringiensis israelensis (Bti) was evaluated for the potential control of dengue vectors in various types of potable water containers. On introduction to containers, the tablet sinks to the bottom and the Bti toxins are found concentrated at the sides and the base, while the treated water column is free of Bti toxins within 24 hours after tablet in...

This study determined a practical method to reduce environmental pollution by wastewater from fish ponds. Water quality in three hybrid red tilapia ponds (0.24 ha) was examined before and during harvest at five water depths of 10, 20, 50, 100, 150 cm, as well the surface pond bottom. All samples were analyzed for BOD, TN, TP, TAN, TS, TSS, SS, with results compared Thailand control standard fre...

A few years ago, William Logan wrote, “Poetry has long been a major art with minor audience.”1 We could more accurately call it many audiences grouped, like the poets, around region, identity, ideology, and artistic affiliations—a fragmentation that makes generalizations difficult. It is not easy to place in larger context three books I am reviewing here—Tyler Chadwick's Litany Wings, Scott Hal...

This review article deals with the documentation of all previous work on propagation Gattan. It was found that induced spawning Gattan is similar to common carp and Bunnei. The sensitive brooders needs a great care during handling transportation. weight 5 were 1.5-10 kg for females 1-2.5 males, age 4-9 3-6 males respectively. artificial breeding season continue from10 March till mid June.

Tilapia is a species with great growth potential. Its production comes from semi-intensive system, such as earthen ponds (EP). Recently, biofloc technology (BFT) appears an option to intensify fish production. The objective of this work was compare the organosomatic indices, biochemical parameters, and chemical composition tilapia reared in EP BFT. Fish were grown for 150 days, initial weight ≅...
