Kajian penangkanapan udang putih kecil (Metapenaeus lysianassa, de Man 1888) sebagai aplikasi pengelolaan di muara Sungai Kakap Kabupaten Pontianak Kalimantan Barat
Abstract
Small white shrimp (Metapenaeus lysisanassa) fishery using setnets in Sungai Kakap estuary increased from the year 1994 to 2005 and this sector gave a lot of benefit for fishermen. The advantages of this shrimp fishery are providing work and income for local people, providing of nutritious food for human life and local government income from tax or retribution. However, the increasing fishermen effort to catch small white shrimp in this estuary is estimated to be followed by decreasing of their productivities and declining of CPUE trend. The objectives of the study are to obtain distribution pattern of small white shrimp caught by setnet and to obtain CPUE (Catch per Unit Effort) trend of small white shrimp fishery. Eleven stations were established in this site to learn distribution pattern of small white shrimp caught by setnet and time series data of catch and effort was used to calculate the trend of CPUE. The study got information that distribution pattern of small white shrimp was caught in higher numbers in salinity interval 5 – 7‰. Bigger sizes of small white shrimp were found in salinity 10 - 20‰. CPUE of small white shrimp caught by setnet tends to decrease during twelve years.The study result is expected to give information for management plan to manage of small white shrimp fishery.
