Cage culture is one of the important methods for intensive culture of tilapia in large water impoundments. But, information related to growth performance of androgen-treated monosex tilapia population during cage culture under the ecological conditions of India is limited. The aim of this study was to compare the growth potential of control, mixed-sex and androgen-treated, monosex tilapia in co...

this study was carried out to determine the appropriate size of caspian trout ( salmo caspius kessler, 1877) juveniles for releasing into the rivers that enter south of the caspian sea for stock enhancement, or possibility of cage culture in the caspian sea. a total of 1611 specimens in 4 weight groups of 5, 10, 15 and 20g were exposed to 3 salinity trials which include caspian sea water (11- 1...

Little is known about the growth performance of sex-reversed, all male Oreochromis niloticus under different traditional and non-traditional culture methods practiced in India. In this study, 17"methyltestosterone treated monosex tilapia was cultured in concrete tank, flow-through system, cage, pen and earthen pond. Similar feeding regime and stocking density of fish were maintained for all the...

—The flannelmouth sucker Catostomus latipinnis is one of the few native fish that persists in the lower Colorado River basin. Little is known about the effects of hypolimnetic releases of cold, swift water from Colorado River dams on flannelmouth sucker populations. We conducted fatigue velocity tests on age-0 flannelmouth suckers in the laboratory to evaluate the effects of water temperature a...

Several species of fresh water fish including common carp (Cyprinus carpio), rohu (Labeo rohita), mrigal (Cirrhinus mrigala) and rainbow trout (Oncorhynchus mykiss) are being farmed in India in order to meet the increasing demand for fresh fish. Among the fresh water fishes, rainbow trout is farmed in many parts of India. Worldwide, farmed trout production is increasing. The demand for trout in...

The study evaluated the status of fish pond projects initiated in the 1980s on resource-poor farms in Guatemala and Panama. In both places, the host country and the United States Agency for International Development (USAID) provided financial assistance and Auburn University provided technical support to the respective governments. The study examined the impact of aquaculture technology, extens...

Humic lakes are abundant in the temperate and cold regions of the Boreal Zone. High levels of water colour and strong thermal stratification of humic lakes limit the potential fish habitats and give a special role to the intraspecific and interspecific interactions. Water colour has different effects on species depending on speciesspecific life-history traits and trophic interactions. Fish spec...

Toll-like receptors (TLRs) and nucleotide binding and oligomerization domain (NOD) receptors are pattern recognition receptors (PRRs) that recognize pathogen-associated molecular patterns (PAMPs) and play crucial role in innate immunity. In addition to PAMPs, PRRs recognize endogenous molecules released from damaged tissue or dead cells [damage-associated molecular patterns (DAMPs)] and activat...

This study was conducted in cage aquaculture villages in Hongngu District, Dong Thap Province of Vietnam during November 2001 to November 2002. Cage culture areas are located in the confluence of So Thuong Canal and one branch of the Mekong River. The purposes of this study were to investigate the cage culture system and its related environmental conditions, to determine the quality and quantit...

A new system for automatic detect fault of water quality monitoring devices used in aquaculture is proposed in this paper. The proposed system can detect the whole system which includes platform、gateway、WSN、sensor、 actuator. China is the world’s largest freshwater culture nation which provides 80% of the freshwater culture fish. The water quality is essential to freshwater culture, and the envi...
