The
importance of fish in the diet and nutrition
of rural households in developing tropical countries,
especially in Asia, is well recognized. Declining
catches from common or open access inland capture
fisheries are resulting in declining intake
of fish by low-income rural households who depend
on these resources for their animal protein
requirements. This is resulting in malnutrition,
especially among children. This issue contains
a paper which brings out the importance of small
indigenous fish as a source of calcium, iron
and Vitamin A and the possibility of culturing
these fish along with other carps.
Rice
field fisheries are a major source of fish for
people in many provinces of Cambodia and managers
and development workers should not neglect to
conserve and manage these resources, while promoting
aquaculture and other developmental activities.

Rice
Field Fisheries: A Resource for Cambodia
H.
Guttman
Abstract
Small-scale
fisheries in and around rice fields in the lowland
areas of Cambodia are greatly underestimated and
undervalued. Their contribution to the protein
requirements of the poor rural households is significant.
In Svay Rieng province, they could provide 65-75%
of the animal protein requirements of these households.
The value could well be around 40% of the value
of rice production. It is, therefore, important
that these natural stocks and the fisheries are
managed well and that developmental activities
explicitly consider their impact on these fisheries.

Culture
of Mola (Amblypharyngodon mola) in Polyculture
with Carps - Experience from a Field Trial in
Bangladesh

Abstract
Studies
were carried out during May 1997 to January 1998
in Kishoreganj district in Bangladesh to investigate
the production potential of carp polyculture in
combination with Amblypharyngodon mola
in seasonal ponds. The preliminary results indicate
that A. mola can be successfully cultured
in small seasonal ponds in polyculture with carp.
This practice can result in an increase in the
households’ consumption of small fish which
have a very high content of calcium, iron and
vitamin A. In addition to the nutritional benefits,
it can also provide additional income through
the sale of carp and surplus small fish.

Chemoreception
Studies in Relation to Feeding Responses in the
Marine Shrimps H. Milne Edwards (Penaeus indicus)
and Miers (Metapenaeus dobsonii)
C.H.
Fernandez
Abstract
A study
of chemoreception in relation to feeding and other
factors involved showed that feeding behavior
in shrimps can be triggered by chemical stimuli.
However, P. indicus and M. dobsonii
differ significantly in their chemotactic
response to different stimuli.
