Patterns in morphological variability have been the main basis for conventional genetic improvement program, particularly in selective breeding. Proper understanding on these patterns hence, is of crucial prerequisite before any scheme of breeding program is undertaken. This study was aimed to explore those morphological variations with emphasis on the assessment of among-population and among-trait variations and assessment of predictive traits that may serve for inter-population differentiation. A total 281 individuals representing four natural populations (Asahan, Ogan, Barito, and Ciasem) and one domesticated stock (GIMacro) were sampled and analyzed for variability in thirteen morphological traits. While descriptive analyses were applied to analyze both among-stock and among-trait variations, discriminant function analysis was used to search for the best traits for interpopulation differentiation. The relative variability, expressed in the coefficient of variation (CV), was used to compare the amount and patterns of morphometric variability both among traits and between stocks. Results showed that total body weight was the most variable trait while the length and meristic traits were of lower level. Discriminant analysis found that rostrum length and abdoment length to be the best morphological discriminators among intraspecific populations. However, the continuous natures of these traits make them have limited applicability for intraspecific population differentiation.

Abalone aquaculture attracts wide attention nowadays because of its high market value and depleted of wild stocks. China and Japan are the main producer of abalone from aquaculture followed by other countries such as New Zealand, Australia and US. Most of cultured abalone are temperate species but considerable research efforts have been made to culture tropical abalone in the Philippines, Thailand, and Indonesia. Most of abalone culture still depends on natural food but recent studies have been conducted to develop artificial diet for abalone. This will not only reduce wild harvest of macrolagae but also develop high nutrition diet at low cost. Successful abalone aquaculture is determined by correct nutrition supplement in the diet. As other cultured animal, abalone requires balanced nutrition of carbohydrate, protein, lipid, vitamins, and minerals. As herbivores, abalone can utilize carbohydrate efficiently as energy source and thus only requires low level of protein (range from 27%—40%). Lipid requirements range from 3%—5% while some minerals such as calcium and phosphorus in artificial feed are only needed in small amount, 0.5% of calcium in diets and 0.7% of phosphorus in the diet can improve the growth rate of abalone. There is not available information of vitamin upplementation in the diet but it is suggested that natural food meets the requirement.

Publisher : Center for Fisheries Research, Agency for Marine and Fisheries Research and Human Resource

The family Pangasiidae belongs to the suborder Siluroidei, order Siluriformes, and suborder Ostariophysi. Since the groups were established as Pangasiini Bleeker, 1858; its content and classification have been greatly changed. Judging from the literature, the main constraint to cultivate wild species and to optimize the production of cultured species is needed to the poorly documented systematics of this family. Therefore the objective of the present study is to provide the diagnostic characters and the keys for identification the genera of Pangasiidae. The results clearly demonstrate that biometrically four natural groups can be distinguished. They are the genus Helicophagus, Pangasianodon, Pteropangasius, and Pangasius. The diagnosis of the family, the identification key of the genera and the description are given.

Penaeid shrimp culture is a major contributor to foreign exchange earning in Indonesia. It has significant impact on economic development of fisheries sector, and leads to be one of prime mover to improve social prosperity. However, shrimp industry particularly black tiger shrimp (Penaeus monodon) has been facing unpredictable situation due to disease problem. The main constrain in correlation to the development of shrimp industry is disease outbreak, especially caused by viral agents. White Spot Syndrome Virus (WSSV) occurred in 1994, causing mass mortality of black tiger shrimp almost in all of the middle and western part of Indonesia. Due to the disease problem, it is estimated that in year 2000, more than 50% of shrimp pond were idle. Pacific white shrimp (Litopenaeus vannamei) or “udang vanamei” was introduced to Indonesia at the end of 1999, and released officially in July, 2001. Response of shrimp farmers to the shrimp rapidly accepted and distributed to many provinces in the country. At the end of 2006, distribution of white shrimp culture was encountered in more than 15 provinces. The seeds are mainly produced from hatcheries located in East Java and Lampung. The information of TSV in Indonesia was reported firstly from East Java at the end of 2002, without a clear history. Since then, survey of TSV distribution was conducted intensively in white shrimp production areas. Beside TSV, population of white shrimp coming to Indonesia also susceptible to White Spot Syndrome Virus (WSSV) and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) infection. A survey with the aim to know significant viral diseases of white shrimp is needed to set up an alternative strategy to control them. The survey was conducted, firstly in the main production centers of white shrimp; and planned to be continued throughout the country. Samples collection, diagnostic method and data compiled in this study were collected from both active and passive surveillance. Diagnosis of viral diseases infecting white shrimp in this study was focused on TSV, WSSV, and IHHNV agents. Polymerase Chain Reaction (PCR) test has been used as a major diagnostic technique in this study. Progress report of the study showed that TSV spreading limited in controlled areas. The study proved that WSSV and IHHNV have been found in cultured white shrimp. All of the diseases mentioned above tend to be a significant constrain of future white shrimp industry in Indonesia, and special attention should be given in order to protect wide-spread of particular disease from infected to uninfected ones. Also, briefly current status of white shrimp culture development in the country will be discussed in this paper.

Utilization of Cirata Reservoir for fisheries aquaculture with floating net cage system has been increasing rapidly. Industrial waste existed along watershed brings significant heavy metal pollutant that flows and difficult to control. Consequences of such activities were reflected in the degradation of reservoir environment indicated by sedimentation, water quality degradation and fish mass mortality because of up welling. The objectives of this research were: 1) to obtain data and information on heavy metal content in Cirata Reservoir waters, and 2) to observe and understand the effect of heavy metal to the fish cultured in floating net cage to support aquaculture in floating net cage system. Water quality and fish histology analyses were the methodologies used in this research. Descriptive and laboratory analysis were carry out to analysis the data. Based on observation and descriptive analyses, the content of heavy metal in Cirata Reservoir was classified as worse. Concentration of Pb, Cr, Hg, and Cd in the sample of water and tilapia digestive organ becomes fragile. Infiltration of hemoglobin cell, necrosis, degeneration and pigmentation occurred in body organs when up welling happened. Beside that, during up-welling digestive organ become easily breakable resulted in fish mass mortality in floating net cage. The affinity of hemoglobin to the toxic gas was higher than to oxygen, therefore aeration was not affective and mass mortality cannot be avoided. This was because of various events that occured to the fish and the other water biota that encompassed regular diffusion, bio-magnification, and bio-concentration to fish.

The stable mass seed production technique of marble goby, Oxyeleotris marmoratus has not yet been established due to high mortality occurring on the early juvenile stage and/or after 40 days after hatching (d AH). In order to establish the mass seed production technique, O. marmoratus juveniles of 40 d AH were reared for 60 days to determine growth, survival and digestive enzyme activity at different types of feed (trash fish, artificial feed and Artemia sp. nauplii). Specific growth rate (5.32) and survival rate (91.3%) in juveniles fed Artemia sp. nauplii showed significantly higher (P<0.05) than those of juveniles fed trash fish and artificial feed. At the end of the experiment, the mean specific trypsin, amylase and lipase activities of juveniles fed Artemia sp. nauplii were recorded as 0.04 mU mg protein-1m-1, 0.114 mg maltose mg protein-1h-1 and 9.58 m Units, respectively, and they were significantly higher than those of juveniles fed trash fish and artificial feed. In the present study it was shown that O. marmoratus early juveniles had more efficient digestibility and absorption the nutrient when fed with Artemia.

This experiment was conducted to investigate the influence of vitamin C on growth and survival rate of freshwater prawn larvae. The treatment dosages of vitamin C were 0.0, and 0.75 mg/L. Each treatment was in triplicates and arranged in a complete randomized design. Vitamin C was given to the larval rearing media every three days. Larvae were cultured in six conical fibreglass tanks of 50 L volume installed in a fibreglass tank (2 m x 0.8 m x 0.8 m) filled with water for temperature stabilizer. Each conical tank was stocked with 6,500 larvae (nauplii). Artemia nauplii were given on D3 and egg custard as artificial feed on D9. Larval rearing was done for 25 days in constant temperature (29oC–31oC) using automatic heater. Statistical analysis showed that metamorphosis speed of larvae was significantly affected by adding of vitamin C (P<0.05), but survival rate was similar (P>0.05). Addition of vitamin C also resulted in a better growth of freshwater prawn larvae.
