The Use of Various Proportions of Rough Fish on Giant Trevally (Caranx sp.) Culture in the Floating Net Cages, Pangandaran, West Java
No full textThis research aims to determine the effect of providing rough fish and pellets with optimal dosages on the Giant Trevally culture to produce the highest growth in Pangandaran floating net cages. This research was conducted in August 2019 to September 2019 with 60 days fish rearing. The method used in this study was a Completely Randomized Design (CRD) with five treatments and three replications. The treatments were A (0% rough fish and 100% pellets), B (25% rough fish and 75% pellets), C (50% rough fish and 50% pellets), D (75% rough fish and 25% pellets) and E (100% rough fish and 0% pellets). The effect of each treatment was tested by analysis of variance (ANOVA) F test at an interval of 5%; if there were significant differences then followed by Duncan\u27s multiple range test. The parameters observed in this study included fish survival (SR), Daily Growth Rate (LPH), Feed Efficiency (EPP) and water quality at the study site. The results obtained from this study were the provision of rough fish in Giant Trevally was able to increase the Daily Growth Rate (LPH) and the Efficiency of Feeding (EPP) for Giant Trevally. The highest growth value in this study was in treatment E (with 100% rough fish and 0% pellets) with LPH of 3.01%, total weight of 109.47gr and EPP of 30.60%

Analysis of the Role Cikidang Fish Landing Port (PPI) Towards Fishermen\u27s Socio-Economy in Pangandaran District, Indonesia
No full textThis research was conducted in Pangandaran District, precisely at the Fish Landing Port (PPI) Cikidang Pangandaran. This PPI Cikidang is included in the type D fishing port of the Fish Landing. The research method used is a case study with data analysis using a Likert Scale. The aim of this research is to describe the role of PPI Cikidang through basic port facilities on the socio-economic characteristics of Pangandaran fishermen who work at PPI Cikidang. Based on observations and interviews through questionnaires, some of the main port facilities are still not optimal in their development and function. This affects the catches of fishermen and the activities of fishermen at the port. Some basic facilities that are still not optimal make fishermen more independent in activities without having to wait for facilities to be repaired or developed. The main facilities that have not been optimal are the pier, harbor ponds and fish markets. At the docks and port ponds there needs to be improvement by dredging the bottom of the water so that it can get inside, the tides can be conditioned. In the fish market, its function is still less than optimal because it is only used as a canteen. The improvement is to re-socialize the function of this fish market and try to carry out its function properly by increasing the fisheries business budget around PPI Cikidang

No full textLong jawed mackerel resources are resources that are open access and common resources. The activity of catch mackerel in Indramayu district is increasing every year. In 2018 total fish production was 8423 tons while in 2019 there were 9047 tons. The utilization of long jawed mackerel resources must be based on economic and biological aspects as well as planning a sustainable use of long jawed mackerel. This study aims to analyze the conditions, efforts, and actual production of bloating fishing activities that are sustainable and optimal in Indramayu, as well as providing input into the direction of appropriate input and output management in bloating fishing activities in Indramayu Regency. The study was conducted in December 2019 to January 2020. The method used in this study was a survey method using quantitative descriptive analysis. Sample included 100 patients (age range 15-65 years) with respondents were owner fishermen, crew members, and/or boat captains, respondents were fishing using payang and purse seine.

Benefits of a Biofilm System and Low Ammonia Levels to Decrees the Early Mortality Syndrome in Shrimp Larvae (Litopenaeus vannamei) Infected with (Vibrio parahaemolyticus)
No full textThe world shrimp aquaculture, has faced several problems, causing severe losses in shrimp hatcheries; between the most critical has been diseases such as early mortality syndrome (EMS) caused by (Vibrio parahaemolyticus). The EMS was initially detected in Asian countries; after, it was disseminated to Mexico and other countries. In Mexico, EMS caused severe economic losses during 2013-2016; and it has not yet been eradicated. Various causes for EMS have been reported; none is entirely accurate, but water quality is essential for successful shrimp aquaculture; therefore, the aim this work was evaluate the ammonia concentration effect on susceptibility to (EMS) on post-larvae (PL-15) shrimp (Litopenaeus vannamei) infected with (V. parahaemolyticus), using a biofilm system (water with, microalgae, dinoflagellates, protozoa and other planktonic microorganisms). So series of 5 flasks each one were arranged as following: Series S; 900 ml of filtered seawater (FSW) and 10 PL-15 shrimp per flask. Series SB; 840 ml of FSW, 60 ml of biofilm and 10 PL-15 shrimp. Series E; 900 ml of FSW, infected with 2 ml (V. parahaemolyticus) 106 CFU/ ml and 10 PL-15 shrimp. Series EN; fifteen flasks with 900 ml of FSW, 10 PL-15 shrimp, added with NH4Cl (0.535 mg/ml), to get 0.5, 1.0, 1.5, 2.0 and 2.5 mg/l final ammonia concentration in 5 sub-series of 3 flasks each one. During experiment, ammonia concentration and PL-15 shrimp mortality were evaluated in all flask. Ammonia concentration was higher in series EN than in series E; the same was observed in Series S respect to SB, but at lower values. At end of experiment, mortality in series EN was 90% Vs 60% in E. Similarly, mortality in series S was 10% Vs 0% in SB. This results confirm that the ammonia increases PL shrimp mortality, and biofilm system reduce ammonia and consequently PL-15 shrimp mortality

No full textThis study conducted statistical data retrieval at the fishery port of Nusantara (PPN) Palabuhanratu Sukabumi District, Indonesia to analyze the production of tuna fish. Analyzing the index of production values and analyzing the sustainable catches on the tuna, especially with the Tunas longline catch in PPN Palabuhanratu Sukabumi regency. The study was conducted from November 2019 to March 2020. Methods used are survey methods and quantitative analysis. The results of the study showed the average production of three types of tuna (large eye Tuna, yellowfin Tuna and Tuna Albakor) in PPN Palabuhanratu period 2010-2019 is 5,693 tons/year with the average value of Rp. 99.634.022.955 yearly production, The production of tuna (large eye Tuna, yellowfin Tuna and Albakor tuna) in PPN Palabuhanratu affects 67% of the production of capture fisheries that landed in PPN Palabuhanratu during the period of 2010-2019, then the relative index of tuna production value in PPN Palabuhanratu showed an average value of 1.41, means the production value of the three types of tuna (yellowfin Tuna and Tuna Albakor) in PPN Palabuhanratu is higher than the value of the overall production of fish in PPN Palabuhanratu, with a production of 5,693 tons/year, the production already touched the state of overfishing, because it passed the MSY limit of 4,737.05 tons/year
Evaluation Trial on Production Performance of Freshwater Mud Eel (Monopterus cuchia) in Farmer’s Pond
No full textThe experiment was conducted to evaluate the production performance of freshwater mud eel (Monopterus cuchia) with supplementary feed for a period of 5 months in field level. Two ponds were selected for this experiment in Maulovibazar district. Baby cuchia having weight of 50-70 g were stocked in ponds at a stocking density of 10/m2 in filter net. Liming (CaO) was done in all the ponds at rate of 250 kg/ha. A safety shelter for cuchia was developed by installing bamboo root, plastic and bamboo-made hollow pipe, aquatic vegetation and necessary objects in the pond. Different physico-chemical parameters were found to be within the acceptable ranges for M. cuchia culture in all ponds. Supplementary feed composed of fish paste (50%), fish meal (40%), rice bran (5%) and wheat flour (5%) was applied at the rate of 2-3% of body weight. After 5 months of rearing, total production obtained were 28.3±1.09 and 31.9±2.56 kg from pond-1 and pond-2, respectively. The highest production was obtained from pond-2 and lowest production was obtained in pond-1. The net profit gained from pond-1 and pond-2 were tk 2559 and 3211 per decimal, respectively
