Abstract

A study aims to find out the domestication and triggering gonadal maturation techniques of Thynnicthys thynnoides obtained from Kampar River, Riau has beenconducted from June to August 2009. Fish samples were kept in 1 x 1 x 1 m cages,30 fishes/ cage. Fishes were fed on three types of food namely dried Tubifex, shrimppellet (without vitamin E addition) and shrimp pellet that is enriched with vitamin E(100 gram/ kg ). The food provided was 5% of total fish body weight/ day.Result shown that fish domestication can be conducted by keeping them in the cagesthat are placed in the area where the fish are captured. During the first week, fisheswere not fed and in the following weeks they were provided with the treated fed. Thebest result obtained in the fishes that are feed with shrimp pellet that is enrichedwith vitamin E. During the research period (8 weeks), 12 fishes were sampled and 5of them were in the 4th gonadal maturity level, their maturity indices was 15.603%,fecundity 19,516 eggs, egg diameter 1.07 mm and semen volume produced 0.945 ml.Key words : domestication, maturity indeces, fecundity egg diameter

Abstract

This research was conducted on June 2009, located in Estuary Kampar Rivers, Pelalawan Regency, Riau Province. It was aimed to understand study andanalyze the characteristics of the sediment and the possible applicability in the Kampar River Estuary. Results of laboratory analysis of sediment samples obtainedgrain size distribution of five types of sediment texture, namely: sand, sand silt,sandy silt, silt, and sandy mud. Heavy mineral analysis of heavy minerals obtained 9,3 light mineral, and clay minerals. Heavy minerals obtained in the form of magnetite,kasiterit, zircon, tourmalin, pyrite, amfibole, ilmenite markasit, and pyroxene,whereas for minor minerals, namely quartz, muscovite, and biotite. Chemicalanalysis of sediment samples obtained rare earth elements, such as tantalum, ytrium,zirconium, and content kasiterit associated with other minerals.Key words : Sediment, Sand, Bono

Abstract

The aims of the research are : 1). to identify both the potential and the typesof utilizations of mangrove ecosystem carried out by the local society, 2). to analyzethe economic values of the mangrove ecosystem, and 3). to analyze the alternativesof the strategic utilization for mangrove ecosystem. The number of respondents is58 deriving from fishery household (RTP) and non RTP. The data were thenanalyzed by using consumer surplus, Total Economic Value (TEV) and MultiCriteria Analysis (MCA).The results show that biggest utility is the one of crabs that reaches Rp113,647,959 with the surplus consumer of Rp 27,780,612. The highest optimumprofit from arang bakau utilization amounts to Rp 360,732 for 11 (eleven)households, while the lowest profit is obtained from the utilization of prawn pondwith Rp 424,839. The biggest proportion is from the indirect utilization with apercentage of 85,58 % with a value of Rp 116,375,900,400 per year. Furthermore,the Total Economic Value of the mangrove forest ecosystem in East Bintan Districtcovering 2 ha for ponds, 1100 ha for HPHH licency and 3354,29 ha of mangroveforest amounts to Rp 135,977,965,849 per year. The utiliation alternatives put aspriorities, based on the balance between indicators for both efficiency criteria andecology criteria, between the efficience and equity criteria in the level oef interestrate 0f 10 % are as follows : firstly, utilization alternativ III (100 % mangroveforest), secondly, utilization alternative II (1100 ha mangrove forest by licencyHPHH and 33356,29 ha mangrove forest. Nevertheless, the utilization alternativ Ican not be given as choices in this management because utilization of prawn pondnot efficient.
