Abstract

Different media condition, with salinity above the hatching threshold of cysts (100 ppt) and feeding with water flow as the main menu and Spirulina maxima flour as an additional feed encouraged the adult female Artemia salina to be oviparous and produce different amount of cysts depending on the treatments. The average amount of cysts produced by oviparous female Artemia salina during 77 day rearing was 22,719-78,616 cysts each female Artemia salina produced 18-13 cysts. Statistical analysis showed that all treatments did not reduce any significant effects on the production of cysts (p>0.05)

Abstract

A study aimed to identify morphology variability of nile tilapia (Oreochromis niloticus) strain GIFT (Genetic Improvement of Farmed Tilapia) by using standard measurement and multivariate analysis method was conducted. Elevan characters were measured at 141 fishes representing 3 levels of age (0-3 month, 3-6 month and more than 6 month) of nile tilapia strain GIFT. Multivariate analysis of variance (manova) and Pricipal Component Analysis (PCA) were applied to explore the morphological variability.The result showed that body shape of fry (0-3 month of age) was different from fishes with 3-6 month of age (consumption size), also from the broodstock. At the early level of age, development of the body shape was growth in width and length. At the consumption size and broodstock levels, the development of body shape was growth in fat too.

Abstract

The aims of this research were to know the state of small pelagic fishery and social economic aspect of resources exploitation. To examine these issues, the research combined survey and descriptive analytic methods. Gordon-Schaefer model was applied to analyze the state of fishery and analytical descriptive to explained the relationship of the phenomena's. Data collection was based on indepth interview and recording of District Fishery Service's. Samll pelagic fisheries that been analyzed were anchovies (Stolephorus sp.), squids (Loligo sp.), and mackerels (Rastrelliger sp.).There are two main problems of fisheries in the area, firstly, the conflict on coastal zone between marine capture fisheries and mariculture. The second one is the intensive exploitation of fisheries resources. Pelagic fisheries at Sape Bay have been exploited above maximum TAC mainly 80% of MSY. MSY of anchovies (Stolephorus sp.) reached 2324,9 ton at number of effort 56534 trip and MEY 2172,3 ton at number of effort 42144 trips. MSY of squids (Loligo sp.) is 455,0 ton at number of effort 12183 trip and MEY 449,0 ton at number of effort 10780 trips equal to Bagan Perahu  trips. The model was not applicable to predict the MSY and MEY of mackerels (Rastrelliger sp.). The continuing increase of effort will depleted the stock and decreased economic rent. In addition, the increasing of competition on fishing ground with pearl culture, have resulted fishermen stress. The integrated policy and management are needed to solve these problems and to avoid social riots.

Abstract

Study on sensitifity of two shrimps species, there were blue shrimp (Litopenaeus stylirostris) and giant tiger shrimp (Penaeus monodon) against local isolat of SEMBV (systemic ectodermal and mesodermal baculovirus) has been undertaken. The objective of  the study were to know sensitivity level of the two shrimp species to virus that cause serious disease namely WSDV (white spots disease virus). Result from the study showed that both shrimps are sensitive to the virus. Inoculating virus through injection caused  transmission faster than that by feeding shrimp with infected carcass. Blue shrimp also showed relatively sensitive to SEMBV then that of giant tiger prawn.

Abstract

The aims of this research were to know the history and development of fisheries activity and its contribution to coastal community welfare at South Coast of Yogyakarta Special Territory Province. To examine these issues the research was conducted by combined survey and descriptive analytic methods. Fisheries in area could be categorized as new activity and historically community does not have a high dependency on marine capture fisheries. Fishers were  farmers who become fisherman due to several reasons such as limitation of land and lack of other job opportunity. Since the activity began in the end of 1970’s at Baron, marine capture fisheries have altered income sources, improve community houses, and attracted young people as well as provide productivity activity for rural women. In the recent time, marine capture fishery has dispersed to all of Yogyakarta South Coastal area at 19 fish-landing places with vary intensity of resources exploitation. Marine capture fisheries are still limited in the coastal zone. Although CPUE tend to increase, the activity should be extended to province management zone and ZEEI. The integrated policy and management are needed to solve these problems and to avoid the tragedy of the commons.
