Effective aquaculture extension service is the source of information and technologies to farmers, as well as, feedback to researchers and policymakers about the aqua farmers’ problems, needs and concerns. Information is a critical resource in the farming practice and it is the basis of extension service delivery. Effective Research-Extension-Farmer (REF) linkage ensures that farming innovations...

Heritage conservation is an important recurring research theme on agricultural heritage systems. Improving the income of farmers from agriculture is regarded as an effective conservation approach. This study examined how the improved rice-fish-duck coculture (IRFDC) promotes the protection of the Honghe Hani Rice Terraced System (HHRTS) by keeping farmers farming in their hometowns. A semi-stru...

The population of Bangladesh is increasing tremendously and to keep pace with the increasing demand of fish protein, farmers intensified fish production from the water bodies which created environmental pollution. To tackle the situation the raft and rack aquaponics experiment was conducted to reduce the water pollution and have vegetable production from high density poly-culture fish ponds. Th...

BACKGROUND The ubiquitous and opportunistic bacterial pathogen Aeromonas hydrophila has been associated with ulcerative dermatitis in fish, especially under stressful conditions. It can cause severe losses in fresh water aquaculture and is particularly prevalent in tropical and subtropical regions. Fresh leaves from maize and bananas have been used as feed supplement by fish farmers in Vietnam ...

The aim of this study was to investigate the feasibility of two detection methods for use in discrimination and sorting of adult Atlantic cod (about 2 kg) in the small scale capture-based aquaculture (CBA). Presently, there is no established method for discrimination of weaned and unweaned cod in CBA. Generally, 60-70% of the wild-caught cod in the CBA are weaned into commercial dry feed. To in...

The study was conducted in Adamawa State, Nigeria. The major thrust of this study is to assess the adoption rate of technology in Fadama III project, Adamawa State, Nigeria. Fadama III is being implemented in 20 Local Government Areas (LGA) of Adamawa State.

Social interactions among multiple user groups of tank irrigation systems were studied to propose policies for sustainable management of tanks. Crop growers are the major competitors for water besides encroachers, fish and duck farmers. Existence of week property rights remained as the reason for the competition among users that subsequently led to conflicts. Conflicts aroused among user groups...

for cage culture. Species which have been researched and successfully reared in cages in the southeastern region of the U.S. include: catfish, trout, tilapia, striped bass, red drum, bluegill sunfish, crappie, and carp. Other species may be suitable for cage culture but research has lagged behind other aquaculture research in recent years. Interest in cage culture has been revived as an alterna...
