Abstract

New technology in catfish farming is starting to be used, one of which is the use of probiotics in GWS (Green Water System) fish farming. This research aims to provide information to fish farmers regarding the appropriate and appropriate use of probiotics in cultivating catfish (Clarias sp.) using the Green Water System (GWS) method. The design used was three treatments and three replications, namely 1) treatment of bacterial yeast composition, lactic acid and probiotics, basillus subillis, basillus megaterium, basillus polimyxa; 2) probiotic treatment of fish salt, molasses, dolomite lime, and probiotic lactobacillus casei, saccharomyces cerevisiae; and 3) probiotic treatment of dolomite lime, probiotic saccharomyces cerevisiae, lactobacillus acidophilus, bacillus subtilis. The research results showed that the addition of probiotics in composition 1 was the best formulation in the green water system water media for fish survival rate, namely 91.41%, daily weight growth, namely 0.91 grams per day, and feed conversion ratio value, namely 1.18. The results of measuring water quality parameters obtained from treatment 1 provided high growth of plankton and bacteria in the GWS water media. In general, the water quality parameters in the three treatments showed an optimum range for DO parameters of 5.5 - 6 ppm, temperature 28 - 28.6 0C, and pH 6.5.

Abstract

The improvement of Indian mackerel fishing activities in the Natuna Sea can be accomplished by providing information about water characteristics to analyze the optimal fishing timing. This study aimed to investigate the water characteristics that affect Indian mackerel fisheries using data from CROCO model (sea surface temperature and salinity) and Indian mackerel (Rastrellinger sp.) landing data at the Pemangkat Nusantara Fishing Port. The results showed that the peak of the Indian mackerel fishing season occurred from southwest to northeast. During this period, the waters of the Natuna Sea were characterized by warm temperatures (greater than 29 °C) and low salinity (less than 33 PSU). During this period, the relatively stable and less extreme water conditions in the Natuna Sea were associated with the high abundance of mackerel in these waters.

Abstract

Ocean coastal waters are coastal areas that have an important role economically and environmentally, with activities such as fisheries, tourism, and sea transportation. These waters often experience sea wave phenomena which have an impact on human activities, coastal infrastructure, and marine ecosystems. This research aims to determine the characteristics of sea waves in the coastal waters of Samudera Indah, Bengkayang Regency, West Kalimantan. The data used in this study on the characteristics of ocean waves are primary data and secondary data. The data is wind data for 10 years (2012 – 2022) which comes from data from the European Center for Medium-Range Weather Forecasts (ECMWF). Forecasting and determining the characteristics of sea waves is carried out using the Sverdrup Munk Bretschneider (SMB) method which is obtained from wind data. Based on analysis of wind data from 2012 to 2022, the height and period of significant sea waves in the west season are generally greater than in other seasons, namely 0.37 meters and 2.74 seconds. On the other hand, the average height and period of significant sea waves in transition season I are lower compared to the west season, east season and transition season II.

Abstract

Tides and currents influence the dynamics and biochemical circulation in a bay or estuary. This research aims to conduct an initial study of tides and currents in Bengkolan Bay, which is home to the mangrove ecosystem in West Kalimantan Province. Elevation and current measurements were carried out for 15 days at the mouth of the Kapuas River Sepok Pangkalan (north side of Bengkolan Bay) using tidal palms and drifters. The measurement results show that the pattern of water surface movement and currents at the research location is very dependent on ocean tidal patterns. Diurnal tides play a very large role (10 times) compared to semidiurnal tides. This big role causes the type of tides in Bengkolan Bay to be diurnal. Although semidiurnal tides have a small contribution, shallow water tidal constituent are actually caused by semidiurnal tidal energy dissipation.

Abstract

Betta fish (Betta sp.) is an ornamental fish that is in great demand by ornamental fish lovers. The characteristics and features of male Betta fish have a higher economic value than female Betta fish. One way to increase the number of male Betta fish to meet market demand is by masculinization. Fish masculinization strategies can be carried out by administering synthetic androgen hormones in the form of 17α-methyltestosterone (MT). Masculinization of fish using MT shows success in fish in increasing the number of male individuals compared to without hormone administration. The use of the synthetic hormone 17α-methyltestosterone has been prohibited in aquaculture activities because it is difficult to degrade naturally and has the potential to pollute the environment. Several other ingredients that can be used as alternatives to replace synthetic hormones are honey. This research uses honey from different types of bees with the aim of getting the best results for the percentage of male Betta fish in masculinization efforts. CRD research method (Completely Randomized Design) with 3 treatments and 4 replications. The treatments applied were T1 (Apis cerana), T2 (Apis mellifera), T3 (Trigona sp.). The best treatment was T3 (Trigona sp.) which had an effect and was very significantly different with a male percentage of 82,63 % followed by T2 (Apis mellifera) which had an effect and was not significantly different with a male percentage of 71,06 %, and T1 (Apis cerana) had an effect. and not significantly different from the male percentage of 64,45 %.

Abstract

Filet is a food ingredient that is easily damaged and spoiled, so efforts are needed to extend the shelf life of filet by preserving it using low temperature storage and natural preservatives. This research aims to determine the salt concentration in the cavendish banana peel fermentation solution that is best for the shelf life of tilapia fillets. The method used in this research was experimental with four treatments, namely soaking tilapia filets in a fermented solution of cavendish banana peel with a salt concentration of 0%, 2%, 3% and 4% for 30 minutes, then storing at low temperature (5-10̊C). Observations of fillets treated with 0% salt concentration were carried out on days 1, 3, 6, 7, 8 and 9 of storage, while fillets treated with salt concentrations of 2%, 3% and 4% were carried out on days 1, 4, 7, 8, 9, 10, 11, and 12 of storage. The parameters observed were the number of bacteria (TPC) and the degree of acidity (pH), each carried out in duplicate. The research results showed that tilapia filets with 0%, 2%, 3%, and 4% salt cavendish banana skin fermentation solution had storage limits each of up to 6 days 19 hours, 7 days 2 hours, 8 days 8 hours, and 7 days 22 hours. Cavendish banana peel fermentation solution and the addition of 3% salt concentration is the best treatment with a Total Plate Count (TPC) value of 3.6 x 106 cfu/g and a pH value at the storage limit of 6.0, and can inhibit the growth of spoilage bacteria to the limit. maximum storage 8 days 8 hours.

Abstract

The tuna longline is a commonly used fishing gear among fishermen, especially in Benoa, Bali, for capturing large pelagic fish, primarily tuna, in offshore waters over an extended period. This study aims to identify the techniques for operating tuna longlines and to observe the handling process of the catch on the KM Mutiara 26 vessel. The research employs a qualitative descriptive analysis method. Findings indicate that the longline operation on KM Mutiara 26 involves preparatory steps followed by three operational phases: setting, soak time, and hauling. The fishing operations were conducted in the Indian Ocean at coordinates 30° – 32° South Latitude and 103° East Longitude. KM Mutiara 26 is a 122 GT fiberglass vessel powered by a 671 KW Cummins engine and equipped with 11 refrigerated holds. The vessel operates on a two-month cycle. The main catch species was southern bluefin tuna (Thunnus maccoyii), with a total of 242 fish, while the lowest catch was albacore (Thunnus alalunga), with 24 fish. Fish handling involved a four-step process, and storage of the catch was carried out using a freezing method.
