We analyze the problem of an integrated management of fisheries by using fish farming as a tool for restocking fish populations depleted by overfishing pressure. We first use a simple heuristic dynamic model, taken from a classical example of mathematical bioeconomics, in order to prove that fish restocking may be an efficient tool for sustainable fishery management in situations where excessiv...

Fish and other organisms with aquacultural potential live in water, thus, it is no surprise that professional fish culturists state that "Water quality determines to a great extent the success or failure of a fish cultural operation" (Piper et al. 1982). Because water is an essential requirement for fish farming, any properly prepared business plan for aquaculture must describe the quality and ...

The Peiligang Culture (9000-7000 cal. yr BP) in the Middle Yellow River region, North China, has long been considered representative of millet farming. It is still unclear, however, if broomcorn millet or foxtail millet was the first species domesticated during the Peiligang Culture. Furthermore, it is also unknown whether millet was cultivated singly or together with rice at the same period. I...

In order to save natural resources and supply good fishes, it is important to improve fish-farming techniques. The survival rate of fish fry appears to become higher when powders of foraminifer limestone are submerged at the bottom of fish-farming fields, where bacterial biofilms often grow. The observations suggest that forming biofilms can benefit to keep health status of breeding fishes. We ...

To facilitate sustainable agricultural development, this study developed a model of rice farming sustainability in Bangladesh and determined the key interventions for policy implementation. Data for the study were collected through a household survey and also via in-depth informal discussion with stakeholders. By constructing a composite indicator, path analysis results showed that major contri...

Vietnam has become the second largest rice exporter in the world. However, the food security is still a local urgent necessity for the farmers in several parts of the country, particularly, in area where most of arable land used to low paddies have been transferred to uncertain crops causing many difficulties to farmers on their food need. The current and potential contributions of aquaculture ...

Wangkal Village is one of the villages in Gading District Probolinggo Regency that has agricultural potential supports tourism development. Agricultural includes abundant water conditions so people prefer to grow rice every year and be used for freshwater fish cultivation. Another now exists village Nolobranti River Tubing tour. This tour offers concept tubing down river along Wangkal. dry seas...

The present study was conducted to examine the impact of cage aquaculture on benthic communities in coastal areas (depth 25 to 50 m) from fish farming operations located along the southeastern Black Sea (Ordu-Perşembe, Trabzon-Yomra and Rize central). Sampling was conducted seasonally from April 2007 to 2009. Sediment samples were taken using Ekman Grab (box core- 0.04 m2). Temperature, salinit...

Using data collected from 400 farming households in the Casamance area of Senegal, the paper demonstrates that not only farm and farmers' characteristics, but also farmers' perceptions of technology-speci®c characteristics, signi®cantly in ̄uence adoption decisions relating to improved rice varieties. Farmers' perceptions about improved rice varieties were quanti®ed using a quasi-arbitrary ordin...
