Collection and maturation of broodstock of the black tiger shrimp Penaeus monodon

Forty (40) broodstock of the black tiger shrimp, Penaeus. monodon, comprising of 16 males and 24 females were collected between November and December 2008 from three Nigerian Fishing Companies namely Karflex Fisheries Nigeria Limited, Honeywell Fisheries and ORC Nigeria Limited. The body weight ranged from 72.5 to 300g, total length from 24.0-34.0 cm and carapace length from 8.0-24.5cm. Abdominal length ranged from 10.3 - 16.0 cm, and telson length from 3.0-5.7cm. The stages of ovarian development ranged between 0 and 3.5 while the percentage of sperm carried by the females ranged from 0 to 100%. The broodstock were stocked in the maturation tanks in the Nigerian Institute for Oceanography and Marine Research shrimp hatchery and fed on squid to enhance gonadal development and maturation. Spawning of P. monodon was successfully carried out three times with an estimated production of one to two million nauplii at each spawning. Three hundred and twenty (320) post larvae (PL30) were stocked in concrete tanks for broodstock development. The post larvae have presently attained juvenile stage with average body weight of 16.01g. The availability of broodstock of P. monodon in Nigerian coastal waters will ensure successful hatchery production of post larvae for stocking of ponds leading to the development of shrimp farming.
