Abstract

GROWTH OF THE DEEP-WATER MUD SHRIMP SOLENOCERA MELANTHO DE MAN, 1907 (DECAPODA, PENAEOIDEA, SOLENOCERIDAE) IN KAGOSHIMA BAY, SOUTHERN JAPAN BY JUN OHTOMI and SHINYA IRIEDA Faculty of Fisheries, Kagoshima University, Shimoarata 4-50-20, Kagoshima 890, Japan ABSTRACT The deep-water mud shrimp Solenocera melantho is commercially important as the main target species for small-scale trawlers in Kagoshima Bay, southern Japan. A total of 4,837 specimens were collected from the central area of the bay from January 1993 to June 1994. Length frequency analysis was used to examine the growth and longevity of S. melantho.
