Abstract

An evaluation of the quality of the Black Tiger Broodstock Shrimp (Penaeus monodon) in the southern coastal area of Pangandaran, West Java was conducted during period of Juny-October 2005. The evaluation was focused on the waterquality identification and the quality of the broodstock collected from the farmer sorround the Pangandaran Area. The result of the evaluation showed that the water quality of the coastal area of Pangandaran was good compare to the northern coastal area of West Java in which the organic and inorganic pollutantwas . This situation was affected on the quality of the broodstock. The identification result on the quality of broodstock using polymerase chain reaction (PCR) method shows that the broodstock shrimp of the Black Tiger Shrimp(Penaeus monodon) in the coastal area of Pangandaran is free from the White Spot Syndrome Virus (WSSV) and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV). From 99 broodstock identified, only 4 indicated by very light contaminated WSSV and 2 by IHHNV. This condition shows that in general the quality of the broodstock shrimp of the Black Tiger Shrimp (Penaeus monodon) in the coastal area of Pangandaran was excellent and these sources are potentialto be applied as broodstock sources for developing the Black Tiger Shrimp (Penaeus monodon) culture in the national level.

Abstract

The key success of producing grouper seed depends on the availability of high and complete nutritive live food (zooplankton) during larvae development stage. Rotiferand Artemia are common zooplankton that has been used in most of grouper hatchery. The cysts of Artemia is expensive because it’s still imported, therefore potential zooplankton from Indonesians waters should be developed to replace or to substitute Artemia. Copepod Oithona sp can be found easily in Indonesian marine waters. Oithona sp can be developed to adult stage within 7 days. One female Oithona can produce 8 to 22 nauplii with average 14,39 ± 3,62 nauplii. The larva ofhumpback grouper (Cromileptes altivelis) fed by Oithona sp showed a higher DHA content (0,30 % b/b) than those fed by copepod + Artemia (0,15 % b/b) and and Artemia only (0,03 % b/b). The EPA content in larva fed by Oithona also showed thehighest, 0,30 % b/b. However, improvement technique of monoculture Oithona should be carried out due to mass mortality and contamination by protozoan and rotifer.
