Abstract

This study aimed to examine polyculture of seaweed and vaname shrimp in laboratory scale to prevent V. harveyi infection. Study was conducted with a completely randomized design by 3 treatments and 3 repetations. Application of seaweed were 800 grams (P8), 400 grams (P4) and without seaweed (control). Challenge test was carried out for 10 days with bacteria concentration of 106 cfu/ml/ind in 10 shrimp using aquarium containing 100 liters of sea water. The result showed that polyculture of seaweed and shrimp could not maintain the survival rate of shrimp significantly but could suppress the population of V. harveyi in waters. Survival rate respectively from control, P4 and P8 were 60.0%, 73.3%, 76.7%. Population of bacteria in treatment was lower than control on 10th days after seaweed stocking until challenge test. Aplication of seaweed could also accelerate shrimp recovery time from bacterial infections observed in clinical symptoms that return to normal on 9th days after challenge test. Total hemocyte count (THC) were better observed in shrimp cultured seaweed on 10th days after challenge test, and differential hemocytes count (DHC) were better on 5th days after challenge test. Polyculture of seaweed and shrimp has potential to improve shrimp health status.

Abstract

The aim of this study to observe the reproductive performance and larval development of white shrimp broodstock with adequate feed and water quality control programs. The stages of research were preparation of cultivation media, selection of broodstock, spawning, hatching and rearing of larvae. The broodstock that were spawned came from Hawaii with a weight of 35 g/ind for the male broodstock and 40 g/ind for the female broodstock. The broodstock were fed with marine worms and squid. The larvae were given natural diet in the form of Artemia salina, Thallassiosira sp. and Skeletonema costatum and artificial feed. The results showed that the reproductive performance of the broodstock was observed with the number of eggs 102.400.000 eggs from 667 broods, the average fecundity per broodstock were 143.986 eggs, the number of naupli was 75.520.000 individuals, the hatching rate was 60.9%. Larval development starts from the egg stage which undergoes embryogenesis, hatches into naupli 1-6, then becomes zoea 1-3, mysis 1-3 and post-larvae (PL). Length growth from PL1-PL8 was 3.95-8.05 mm with a survival rate of 43.95%. Water quality during rearing is still in the optimum range for the growth of broodstock and shrimp larvae.
