Abstract

Shipworm is specialized as wood borer bivalve.They has a pair of shell which reduce to a small but highly efficient cutting organ at the extreme anterior end by which they bore the woods up to 19 mm a day. Shipworm derives some nutrition from the wood that they swallow with enzymatic mechanizm and bacterial simbionts. They store their products of digestion in the form of glycogen and fat. Mangrove is their natural habitat, and they also play an important ecological role in the reduction of mangrove woods. Syaputra (2003) has reported that shipworm which lives in Mangrove ecosystem near Tanjung Batu Village is from genus Bactronophorus. It is based on Allan (1962) who said that shipworm with stilt-like pallets, short siphons and the shell with 1.85 cm of length, and total length of pallet reaches 5 cm is Bactronophorus. As the other fisheries coomodities (crabs, shrimps, etc), shipworm could be an alternative source of health food by providing the essential fatty acids. Until now, we still have to catch the shipworm from nature, so that, the yields would be depend on the carrying capacity, catch per unit area, and catch season. For the future, it is important for the stakeholders altogether assuring that our mangrove ecosystem still provides nursery and feeding ground function especially for the shipworm.

Abstract

Salt is one of strategic commodities. Beside for public consumption, salt has been created for Iodium fortification to become Iodium consumption salt in order to prevent health disturbance caused by lack of Iodium consumption. Salt also known as one of Sodium and Chloride source, which is needed for metabolism process of human body. From the fact that degradation of productive area is taken place, this study directed into a spatial analysis of public salt productivity using study case methods at three salt concentration area in Java – Madura in order to build basic salting propagation in eastern Indonesia. The study result that is concluded from physical variables (elevation, bed rock type, soil type, climate, salinity), demography variables, and technology variables shown : The salt productivity is increasing much more to the east, equal with the increasing of salting land area. The most significant factor to influence salt quality are production technology and physical factor (bedrock type, soil type, drainage area, salinity). Physical factor is not significantly influence, while all salting land area has the similar physiography that elevated two meters below sea level. The most significant factor is culture and people character. Analysis results for salting land area suitability shown that the existing salting land area at study case area still be able to develop especially at Astanajapura sub-disctrict.

Abstract

The research takes 6 stations based on point of compass in the water of Karampuang Island – West Sulawesi Province. The goal of this research is to know feasibility area sight from oceanography physics and chemics for marine culture of seaweed with rope in upper water, floating nets of kerapu fish, sea cucumber and abalone marine culture. Analysis method of feasibility area with the quality for a piece of biophysics parameter is measured not only for supporting factor but also breaking factor for marine culture. The research of feasibility by calculating the total score from all parameters measured in situ with feasibility criteria that the feasibility area is very, enough, and not properly. The seaweed marine culure with with rope in upper water is very proper to develop into the six stations of research, kerapu fish at the station 1,2,3,5 and 6. Sea cucumber at the station 1,2,3, and 4. Pearl Oyster is very proper at the station 1 and 2 and others shows that they are only proper enough with marine culture because of the marine limited factor is bigger than supporting factors

Abstract

Many types of ornamental freshwater fish are economically important commodity for national and international trade. The quality and value of ornamental botia fish is dice to their performance. Performance and productivity of ornamental fish can be destroyed and decreased by parasite infection. The aim of this current research is to inventory the parasite types and their specific attack area on ornamental botia fish (Botia Macracanthus) in Kelekar River, District of Ogan Ilir, South Sumatra Province. This research was done from 1 to 30 August 2005. The fish samples were collected from Kelekar River. Fish observation was done at Biology laboratory, Faculty of Teaching and Education, Sriwijaya University. Before fishes were observed, fish body weight and length were determined, inspection of Botia fish including cover part, mucus, gill, eye, stomach cavity, digestive channel and tendon. All parasites found were made wet and permanent preparat for detailed parasite observation. Data collected in this current research are parasite type, prevalent area and intensity of parasite infection. Data were intended then analyzed descriptively. Fish samples are infected by parasites consist of Ichthypphthirius multiflliis, Ambloplifis Achtheres, Argulus Indicus and Glochidia, which represent ectoparasite. Specific areas attacked by Ichthyophthblus multifiliis and Argulus indicus are fin, husk and gill. Specific area attacked by. Ambloplitis Achtheres and Glochidia is gill. Specific host of Ichthyophthirius Multifiliis is ornamental Botia fish (Botia Macrachanthus). Endoparasite consists of Gordius sp and Proteocephalus parallacticus which attacked digestive fish organ. The prevalent and attacking intensity of Ichthypphthirius Multifiliis on ornamental fish body of Botia (Botia Macracanthus) are 100% and 153, 33, inspectively

Abstract

Trace metals in the aquatic environment are formed either in dissolved or particulate fractions. Within an estuary, the metals are influenced by dilution, adsorption and desorption processes, so their consentrations will be changed through either removal or addition. The objective this study is mainly to determine concentration of Pb, Cd, Cu and Zn in the dissolved phase, in suspended solid and in surface sedimens in the Estuary of Banjir Kanal Barat, Semarang. Field measurement of physical and chemical parameter were done in September 2005 in 7 station within the estuary.The results showed that the concentrations of Pb, Cd, Cu and Zn in dissolved phase were lower than those found in particles and surface sediments.

Abstract

Red tilapia, Oreochromis sp. is a popular fishery commodity because of the advantages such as easy at reproduction, fast growth and has a great taste. But in aquaculture, sometimes these advantages cause a problem to aquaculturist like uncontrolled reproduction. Monosex culture is a solution to face that problem by using sex reversal to male (masculinization). Commonly, sex reversal did by addition of 17-metiltestosteron hormone. But, since the material thought has carcinogenic effect and unfriendly to the environment, so then aromatase inhibitor can be an alternative. The aim of this research is to the effective dose of aromatase inhibitor added in pellet to sex reversal of red tilapia Oreochromis sp. The age of tested fishes are 9 to 13 days after hatching that are given fed treatment with synthetics food contained aromatase inhibitor in different doses (0 mg/kg, 500 mg/kg, 1000 mg/kg, 1500 mg/kg). The research methode a complete random design with 4 treatment and 3 repetitions. A hundred fish are put into 12 aquariums that are filled with 84 litres of water for 100 day periods. The fishes are ad libitum fed 4 times a day during the maintenance period. The use of aromatase inhibitor in sex reversal is able to produce male fishes fenotively. The highest percentage of the male occurred at dose 1500 mg/kg food, that are 78,625 %. Based on the test of variance informed that there is differences in the average of percentage male fishes produced from the 4 different treatments (0 mg/kg, 500 mg/kg, 1000 mg/kg, 1500 mg/kg). From the graphic, it can be seen that there is a pattern informs that the higher of the dose, the higher the average percentage of male fishes produced. Besides that, from the curve of respond between the average percentage male sex (Y) and dose of the aromatase inhibitor (X) result an accessment equation Y = 0,123X + 59,28. Aromatase inhibitor fed through the synthetic food to the Red Tilapia Oreochromis sp. is able to couse a masculinization. Based on the data gained, indicates that the higher the dose, the higher the average of male sex produced
