Asian Journal Of Aquatic Sciences is a journal publishes scientific articles from research by lecturers and other researchers in the waters sector. Focusing on aspects of aquatic ecology for the use of this habitat as an ecosystem for producing food (fisheries and agriculture) and its function for the earth's ecosystem. Covers aspects of biology, physics and chemistry, both for freshwater (rivers, lakes, swamps, reservoirs), brackish waters (mangrove swamps, river estuaries) and marine waters (coastal and offshore seas).

Abstract

The Department of Maritime Affairs, Fisheries and Food (DKPP) of Nagan Raya Regency is a fully authorized body in managing all fisheries, marine and food activities in Nagan Raya Regency, Aceh Province. One important factor in supporting the productivity of capture fisheries is fuel oil (BBM) for small and medium fishermen. The fulfillment of fuel for fishermen is influenced by the length of stay at sea, the distance to the fishing ground, the size of the vessel, the type of equipment used, the vessel used and the fuel used. The fuel recommendation information system for fishermen is influential as the carrying capacity of information effectiveness between the service and fishermen. The information system itself is a group of elements that are interconnected or interact to form a single unit with an approach using quantitative methods and participatory observation. make a solution to the DKPP Nagan Raya as an effort to create a BBM Information System Application with the aim of facilitating an information system or fuel data collection, data collection of fishermen, and data collection of fishermen's catches. The BBM Information System application with a click using the fisherman's android will be greatly facilitated in the BBM recommendation process because it is in accordance with the quota received. In addition, this application method also makes it easier to monitor and report fuel distribution to fishermen, because everything can be integrated and can be monitored directly by the Marine Fisheries Service of Nagan Raya Regency.

Abstract

Research on catfish filet marinade using Arabica coffee aimed to determine the best concentration of coffee was acceptable to the panelists. This research was carried out in July 2021 at the Fishery Products Processing Laboratory, FPIK Unpad. The method used in this research was an experimental method with four treatments adding different concentrations of coffee to the catfish filets, namely 0%, 5%, 10%, and 15%. The parameters observed consisted of organoleptic tests which included appearance, aroma, texture, and taste. The results of the research showed that the catfish filet which was marinated using Arabica coffee belonged to the category favored by the panelists. The treatment with 15% coffee concentration was preferred with a median value of appearance 7 (preferred), aroma 7, texture 7, and taste 7. Based on the Bayes method for decision making, that the panelists chose taste as an important parameter in receiving the catfish filet which was marinated using coffee, followed by aroma, texture, and appearance

Abstract

Pangasianodon hypophthalmus is a freshwater fish that can grow well in dark condition. In no light condition, fishes are more responsive to feed provided. However, phytoplankton may not grow well, and as a consequence the water quality was poor and it negatively effects the fish health in general. The combination of biofloc and photoperiod manipulation systems is expected to improve the water quality as well as the fish health. To understand health status of the fish in general, the histological structure gill, kidney and liver was investigated. Sample were fixed in 5% formalin, paraffin processed and Haematoxylin Eosin stained. There were 2 factor, 3 treatment applied, namely natural (control), 18G (18 hours dark), 24G (24 hours dark) and 3 repetition. Parameter measured were survival rate and histological structure of gill, kidney, intestine and liver. Results shown that there are not difference of histological structure of the organs of fish reared under biofloc and manipulated photoperiod systems. There were light abnormalities in the gill, such as hyperplasia, hypertrophy, oedema and necrosis. There is no negative effect of biofloc system and photoperiod manipulation in structure of fish organ as there is only light abnormalities that can be cured when the water quality is good.
