Recent developments of shrimp, Penaeus monodon (Fabricius) and Penaeus merguiensis (de Man), culture in East Java

Shrimp, Penaeus monodon (Fabricius) and Penaeus merguiensis (de Man), culture on East Java is described with special attention to the differences in production characteristics between areas and districts. Traditionally, tambak culture developed along the North coast of East Java where the majority of modern tambaks are still located. The practice never developed extensively on Madura's Island. With the exception of the latter, intensification, startingin 1984‐1987, touched all areas. In 1991, the combined production of P monodon and P. merguiensis reached 35 000 Mt, representing a value of US$ 220 × 10⁶. The following year, a decline in total production was noted, mainly caused by a diminished production of intensive farms. Possible causes for this production drop are explored.
