Low cost breeding and hatching techniques for the catfish (Heteropneustes fossilis) for small-scale farmers
Type: Journal Article
The high demand for the stinging catfish (Heteropneustes fossilis) and declining wild stocks led the Centre for Aquaculture Research and Extension of India to look for methods for the culture of the species. This paper ...
Breeding plan for common carp (Cyprinus carpio) in Indonesia: multiple-trait selection
Type: Report
Total aquaculture production in Indonesia in 1994 was 493 000 tons of finfish, 169 000 tons of shellfish, mainly shrimp and 115 000 tons of seaweed with an estimated value of US$ 2 075 million. In 1994, the production of ...
Effect of planting pattern on shading and phytoplankton photosynthesis in Bangladesh rice-fish farms
Type: Journal Article
In the present study, a Border Planting (BP) pattern recommended by the Bangladesh Agricultural Research Council was tested against Regular Planting (RP) to assess the effect, if any, on gross phytoplankton photosynthesis ...
Making experiment station results more useful to African fish farmers
Type: Journal Article
Rather than using more or less ideal conditions for setting experimental controls, the use of conditions similar to those likely to be encountered by farmers should produce research results which are realistically achievable ...
Collection of juvenile mullet species from a brackishwater tidal farm in Nigeria
Type: Journal Article
The major constraint to the development of aquaculture in Nigeria has been the non-availability of fingerlings in required numbers of cultivable species. A specifically designed trap to collect mullet (Liza falcipinnis; ...
Can nitrogen pollution from aquaculture be reduced?
Type: Journal Article
Nitrogen is essential for the normal growth of fish. It is an important ingredient in fish feed but is very expensive. There is evidence that nitrogen loading from feeding and metabolic activities of fish can cause pollution ...
Reducing feed costs in semi-intensive finfish culture: an update on mixed feeding schedules and an idea for enhancing endogenous food supply in ponds
Type: Journal Article
Some interesting ideas on improving the cost-effectiveness of feeding in semi-intensive finfish aquaculture are presented.
Tracking nutrient flows in a multi-enterprise farming systems with a mass-balance model (ECOPATH)
Type: Book Chapter
Whether grown for sale or for on-farm consumption, vegetables and other crops are often managed as stand-alone, monoculture enterprises. Integrated farming can help improve the nutrient output-input balance sheet and ...
Using the growth performance index Phi to choose species aquaculture: an example from Kuwait
Type: Journal Article
Following a brief account of the advantages of using the growth performance index in choosing species for culture purposes, an examination is made of growth parameters of Epinephelus suilis and Acanthopagrus cuvieri chosen ...
Fishpen culture as a new production system in dammed valleys in the mid-Casamance, Senegal
Type: Journal Article
Fishpen culture is a possible means to increase fish production in Casamance, Senegal and to develop aquaculture without negative environmental effects. To study this possibility, a fishpen study was conducted in two dammed ...
