    Opis:
    Sharks are marine animals that play an important role in marine ecosystems especially as the main predator, thus controlling the dynamics of populations of other organisms at lower trophic levels. Sharks are often caught as a byproduct of capture fisheries in Indonesia, making Indonesia one of the five largest shark contributing countries in the world according to the FAO. A study of shark populations needs to be done to evaluate its stock in nature. The Mayangan Coastal Fishery Port, Probolinggo is one of the largest fishing ports in East Java with the majority of fishing gear used being cantrang. This study will discuss the shark bycatch volume in fishing activities using cantrang fishing gear at PPP Mayangan, Probolinggo. The use of cantrang fishing gear in Mayangan Port Probolinggo has produced around 6242.9 kg of shark production each year for the past 10 years. The highest production was found in 2011 which reached 10980 kg while the lowest was in 2019 with a total production of 412 kg. The pattern of the development of shark catches at PPP Mayangan Probolinggo showed a decrease in the number of catches, indicating the enforcement of law regarding cantrang usage has been well adapted.

    Opis:
    This paper summarises the methodological approach and main results of the Coastal project (Employment and Human Resources in the Fisheries Socio-Economic System). This project had as its main aim the search for alternative futures for the fisheries sector in West Java, with particular attention being paid to the human resources situation and the working and living conditions of the fisheries-dependent populations in the coastal areas. This is a particularly interesting case, since fisheries were once an important activity and they are now in deep recession, even though it is generally recognised that the future utilisation of maritime resources offer an immense potential. As part of the research, a Delphi exercise was implemented involving in two successive stages some of the leading actors and experts dealing with the sector in West Java. Other initiatives were held in the context of the Coastal project providing direct and indirect inputs to the scenarios and recommendations that were put forward in the sequence of the Delphi exercise. Overall, the activities described in the paper contribute to the mobilisation of major actors and to discussions that may have practical implication for the future of the sector - if certain conditions are now met in the follow up to the project.

    Opis:
    Climate change poses special challenges for decision makers in Indonesia related to inherent uncertainties in future climate projections and the intricate relations between climate change, physical and biological systems, and food security. At present, however, coastal and marine subregions do not have the adaptive capacity needed to overcome this challenge. This paper examines the impact of climate change on food security in coastal and marine Indonesia. It aims to inform decision makers with up-to-date information about vulnerability to climate change, and to facilitate the development of adaptation strategies informed by the experience and knowledge of experts. Climate and extreme weather hazards associated with the coastal and marine sectors cover different factors but are related to sea level rise, rising coastal water temperatures, and tropical storms and hurricanes. Potential vulnerabilities for coastal zones include increased coastal erosion which causes changes in coastline, loss of coastal wetlands, and changes in fish profiles and other marine life populations. Adapting to climate change will ultimately require more systematic integration of governance strategies, science, regulatory systems, policy, and economics at an international level to deal effectively with the wide range of impacts projected for Indonesia. This integration will be shaped through formal mechanisms such as the development or modification of laws, regulations, and policies.

    Opis:
    Goldfish is one of the most famous ornamental fish because of its body shape and color which was interesting to be maintained. The purpose of this research was to find the optimum dose of pumpkin and carrot flour combination on artificial feed to increase color brightness of goldfish. Complete Randomized Design with four treatments and four replications were used in the experiment. For the treatments, pumpkin flour 15%, pumpkin flour 7.5% with carrot flour 2.5% and carrot flour 5%, were studied. The parameters observed were color intensity, survival rate, and water quality. The results showed that supplementation of combination of pumpkin flour 7.5% with carrot flour 2.5% gave the highest color intensity of goldfish with TCF code 0815 and score 2.11 with 100% survival rate. Water qualities during the research were still in optimal condition.
