Culture - based fi sheries : Why , what , where , how and for whom ?

چکیده
In the wake of increasing population and rising average per caput consumption of food fi sh and a plateauing off of the traditional food fi sh supplies there is an urgent need to close the increasing gap between supply and demand. It is generally acknowledged that aquaculture would increasingly contribute to closing this gap. Aquaculture production is still and likely to continue to be dominated by freshwater fi nfi sh production well into the foreseeable future, concentrated in developing countries. However, increasing intensifi cation of inland aquaculture is confronted with resource limitations such as land and water, and biological inputs such as feeds and consequently other plausible alternatives have to be explored. One such alternative is to utilise small and medium sized water bodies, which are estimated to be found in great abundance in developing countries of the tropics (e.g. estimated around 67 x 106 ha in Asia alone). These are mostly incapable of supporting even subsistence fi sheries through natural recruitment, but could be utilised, secondarily, for culture-based fi sheries development (CBF). CBF is essentially a stock and recapture strategy, where the stocked fi sh feed and grow on naturally produced food resources, and which are most effective when communally managed. The returns from CBF could be very signifi cant in terms of nutritional as well as monetary benefi ts to the communities. In this presentation the relevant background information on food fi sh needs and the ways and means of introducing CBF practices in inland waters are dealt with. The importance of this environmentally “friendly” practice to enhance food fi sh production in rural communities are emphasised and the way such practices need to be conducted for optimal benefi ts are discussed.

Bycatch, as used in the present study, is the incidental catch of nontarget organisms that occurs to some extent in almost all commercial fi sheries (Alverson, 1994). Some of these incidentally caught organisms may be protected species—such as marine mammals, marine turtles, and seabirds—or they may be fish or invertebrates that are either harvested as target species by other fi sheries, or spe...

The absence of compassion, argues the author, is not the cause of healthcare failures but rather a symptom of deeper systemic failures. The clinical encounter arouses strong emotions of anxiety, fear, and anger in patients which are often projected onto the clinicians. Attempts to protect clinicians through various bureaucratic devices and depersonalization of the patient, constitute as Menzies...
