The co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or ‘sandfish’, with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in tanks with enriched sand substratum. Feedwas supplied on trays, accessible only to shrimp. Survival of shrimp and sandfish was high in all treatments (73-100%).
The present experiment was conducted in twelve earthen ponds 2100-m2 at WorldFish Center research facility at Abbassa, Egypt, to assess the efficiency of African catfish (Clarias gariepinus) in controlling unwanted Nile tilapia (Oreochrmis niloticus) reproduction in grow out and to evaluate the performance of tilapia in polyculture system with catfish under low-input production system.
The word ‘aquaponics’ is a combination of ‘aquaculture’ (fish farming) and hydroponics (cultivation in water). It raises both vegetables and fish in a limited space at a relatively low financial cost by adding diversification in culture technique. In this study, experiments were setup with an aim for integrated culture of fish and vegetables in cost effect aquaponics. Pond aquacponics can contribute to increase in food production and will be more popular than traditional only pond fish culture system due to optimal use of the pond.
While Bangladesh has made significant progress in reducing undernutrition in recent years, a large proportion of the population still do not consume enough vitamin A, iron and zinc to meet nutritional requirements.
In rural areas, more than 30% of the population is stunted, 29% are underweight and 21% are wasted. Young children, pregnant and lactating women are particularly at risk.
