Management of self-recruiting species in aquaculture

In farmer-managed aquatic systems, poor people do not always have the resources to stock ponds with different fish species. Furthermore, in the dry season, water bodies dry out and access to food sources becomes limited. Self-recruiting species (SRS) are animals that do not require repeated stocking in farmer-managed systems and include both indigenous and exotic species. Management strategies for the maintenance and enhancement of SRS include: keeping of breeding stock, re-stocking of collected juveniles, and screening of pond entrances. These strategies help increase the yield of SRS, without extra financial inputs. This makes them particularly important for poor communities, especially during the dry season when access to other waterbodies is limited.
