Composite culture of edible fishes (common carp, Cryprinus carpio; silver carp, Hypopthalmithys molitrix, grass carp, Ctenopharyngodon idella; catla, Catla catla; rohu, Labeo rohita; and mrigal, Cirrhinus mrigala) in rice fields in the Cauvery delta of Tamil Nadu, southern India, resulted in 81.0% reduction in the immature mosquito population of anophelines and 83.5% of culicines. Analysis of f...

Fish farming methods that is suitable for the Iraqi marshes were classified in two main categories: water based and soil methods. In first category it was found floating net cages could be used rivers branches, while fixed shallowest bodies. It there a good opportunity to use Enclosures Pens. The natural grazing method applied wide area all over marsh, especially which enclosed by dams. second ...

Introduction of sahar in cage-cum-pond integration system of mixed-sex Nile tilapia was evaluated using 15 outdoor cemented ponds of 24 m2 (4.9m × 4.9m) size with 1.25 m water depth placing a cage of 1.2m× 1m × 1m size holding 1 m3 water at the center of each pond at Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, for 158 days. The experiment was conducted in a completely r...

Juvenile Chinook salmon, Oncorhynchus tshawytscha, were exposed to simulated high intensity pile driving signals to evaluate their ability to recover from barotrauma injuries. Fish were exposed to one of two cumulative sound exposure levels for 960 pile strikes (217 or 210 dB re 1 µPa(2)·s SEL(cum); single strike sound exposure levels of 187 or 180 dB re 1 µPa(2)⋅s SEL(ss) respectively). This w...

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from December 2004 to May 2005 to determine the most effective kind of trellis for the rice-cum-vegetable production system. The treatments consisted of five crop combinations viz. C0: rice alone i.e. control, C1: rice + bottle gourd, C2: rice + white gourd, C3: rice + ...

The present study reports a double enrichment cum selective isolation based protocol for successful isolation of lactic acid bacteria (LAB) from freshwater fish intestine where it exists in substantially lower population counts. The procedure involved enrichment of homogenized intestinal samples of freshwater fish in de Man, Rogosa and Sharpe (MRS) broth medium followed by further enrichment cu...
