Aquaculture for diversification of small farms within forest buffer zone management: an example from the uplands of Quirino Province, Philippines.

Upland farming systems can have severe negative effects through intensified slash-and-burn activities, erosion-enhancing farm practices on moderate to steep slopes, and further encroachment into forest areas. ICLARM studied, in a 2-year applied research activity, opportunities for the improvement of existing pond management practices in an upland forest buffer zone environment, mainly through integration with other farm enterprises and through the introduction of polyculture.

Polyculture of Nile tilapia (Oreochromis niloticus) and Australian red claw crayfish (Cherax quadricarinatus) in earthen ponds.

The objectives of this study were to determine whether species interaction be-tween the Nile tilapia and the red claw crayfish in polyculture would be synergis tic or antagonistic in terms of growth rate and total production, and to assess the impact of red claw crayfish on tilapia reproduction in ponds.

Growth and production performances of gift strain of Nile tilapia, Oreochromis niloticus L., in ponds and cages under different farming conditions in Bangladesh

The growth and production performances of Genetically Improved Farmed Tilapia strain, known as GIFT, was evaluated along with two locally available tilapia breeds, domesticated as existing Nile and red tilapia strains, and with several carp species under polyculture system in ponds and subsequently in cages under on-station and on-farm conditions in Bangladesh.

Small fish, big nutritional value

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.
