520 |a An inimitable feature of the Kerala state is the occurrence of 30 interconnected backwaters (Kayals) having an area of about 38,828ha. The interconnected backwaters support high biodiversity and rich commercial fish and shellfish fauna. These backwaters are internationally renowned for their aesthetic and scientific values including being a repository for several species of fish and shell fishes. This paper describes the fishery catch structure of Kodungalur- Azhikode estuary during July to December 2009.The average fish production was 1,047 tones. The major fish species recorded were Mugil cephalus, Etroplus suratensis, Ambassis commersonii, Mystus oculatus, Penaeus monodon, Macrobrachium rosenbergii etc. Etroplus suratensis, Fenneropenaeus indicus and Metapenaeus Monoceros 8.35%, 1.91%and 2.19% of the catch respectively. Cichilids contributed 18.48% of the total fish production. The major gears contributed were gillnets, cast nets, stake nets, scoop nets, ring nets, traps and Chinese dip nets. Gill nets contributed 50% of the total fish catch employed for fishing in the estuary exhibited the highest CPUE value (10.8 kg/unit/ hour). The decline in fishery catch and diversity of various stocks has been alarmingly high in the Kodungalur-Azhikode backwater, thus affecting the substance of the fishermen. Many of the species has reached a stage of extinction due to several stress and anthropogenic interventions and modifications, that too particularly the native traditional resources.
