The experiments investigated the reproductive performance of the domesticated broodstock of the silver perch and the relationship between various degrees of oil globule fragmentation and egg quality. Six years old of second generation broodstock (n=3) were evaluated based on the fecundity, fertilisation rate, hatching rate, the degree of oil fragmentation of egg,...
Carotenoids, besides as a natural pigment, may have vital roles in the growth of crustacean. The aim of this study was to clarify the influence of combined carotenoids given since pre-maturation stage on the growth performances, pigmentation and biochemical composition of the whole body of pond-reared tiger shrimp, Penaeus monodon. Two experimental...
Several ways have been done to encounter shrimp disease affecting cultured shrimp in Indonesian ponds in the last two decades. This research was aimed to find out the effect of different application of probiotic RICA4, RICA5, and RICA3 method on survival rate and production of white-leg shrimp (Litopenaeus vannamei) cultured in ponds...

The problem which has still been faced in the Artificial insemination (AI) is the slow of shrimp to molt. Ecdysteroid hormone has been reported to stimulate molting of tiger shrimp. This study aims to isolate ecdysteroid hormone from Cycas revoluta, Portulaca oleracea and Morus sp. and evaluate its effect on molting period,...
Very low naturally mating rate of pond-reared tiger shrimp broodstock is probably due to the slow maturation of the male stock. The aim of this study was to evaluate the salmon gonadotrophin releasing hormone analoque (sGnRHa) in stimulating the gonadal maturation of male stock of pond-reared tiger shrimp. The treatments were three...
This study evaluated metal concentrations in Caulerpa spp. cultured in ‘traditional’ coastal ponds in South Sulawesi and consumed locally as food. Although Caulerpa spp. are a rich source of supplemental dietarynutrients, like many macroalgal species they are also capable of bioaccumulating potentially toxic metals.We measured the metal concentrations of...
Environmental factors in the form of soil and water quality are the important factors of aquaculture pond productivity, including total production (tiger shrimps, Penaeus monodon, and milkfish, Chanos chanos) in Pasuruan, East Java Province. The objective of this study was to analyze the direct or indirect effects of soil...
Vibriosis is one of diseases which often results in mass mortality of Penaeus monodon larval rearing systems. It attacks shrimp of all stages in zoea, mysis and shrimp postlarva stage. This disease is caused by Vibrio spp, particularly Vibrio harveyi (a luminescent bacterium). Several kinds of antibiotics and chemical...
Spatial distribution of brackishwater pond soil has a vital role in the system of bioenvironment including brackishwater pond environment. This research was aimed to determine the spatial distribution of brackishwater pond soil characteristics in Pekalongan City, Central Java Province. A total of 59 sampling points each with two different...
