Abstract

Vannamei shrimp (Litopenaeus vannamei) is one type of shrimp that is widely cultivated in Indonesia. Vannamei shrimp dominates aquaculture in Indonesia which was previously dominated by tiger shrimp (Penaeus monodon). WSSV, a double-stranded circular DNA virus, has become one of the most widespread and fatal diseases in shrimp populations. Therefore, it is necessary to conduct research to detect the WSSV virus that attacks white vaname shrimp and determine the prevalence rate of the WSSV virus that attacks white vaname shrimp in Bengkalis Regency. This study was conducted from February to June 2022. The purpose of this study was to analyze the prevalence rate of the WSSV virus that attacks white shrimp in the Bengkalis Regency. The research method used in this study is a survey method. The results of the morphological examination did not show any clinical symptoms in vaname shrimp. Tests using PCR with specific primers measuring 941 bp showed DNA bands of vaname shrimp samples from 3 locations, namely Bengkalis district, Bukit Batu district and Rupat district. So the prevalence of the research results obtained is 0%.

Abstract

The main factor for the success of bottom longline fishing depends on the type of bait, both natural bait and artificial bait. The bait serves as an attractant for the target fish so that it is attracted to prey on it. In this study, the bait used was a machete, puput, and layur fish. The purpose of this study was to determine the amount, weight and type of catch based on the appropriate type of bait so that it can be a reference for fishermen for optimal use of bait in the operation of longline fishing gear. This research was conducted in February 2022, located in the waters of Bantan Sari Village, Bantan District, Bengkalis Regency. The method used is the experimental fishing method, by operating the fishing gear directly and analyzing using the analysis of variance and the Least Significant Difference test. Based on the research, the catches obtained were debuk fish, gelama, stingrays, and puffer, with the highest catches in terms of weight, namely stingrays as much as 61800 g

Abstract

The waters of Terkul are related to the strait of Rupat. Around the Terkul area, there is an oil and gas industry with transportation, storage, processing, and distribution of oil supplies to various regions in Sumatra through ship transportation. This activity causes the waters of the Rupat Strait to be prone to oil pollution. Oil pollution can reduce the quality of the waters and cause nutrient content in the waters to decrease. Nutrients greatly affect the concentration of chlorophyll-a in the waters. Chlorophyll-a is a pigment capable of photosynthesis and is present throughout phytoplankton organisms. The purpose of this study was to analyze the association of nitrate concentration and phosphate concentration to chlorophyll-a. the study was conducted in April 2021. Waters sample was collected from the waters of Terkul and sample analysis was conducted in the Marine Chemistry Laboratory. The results of the study show that the association between chlorophyll-a and phosphate corresponds to the regression result of obtaining a value (r) of 0.67. Linearly shows a strong relationship

Abstract

The research was conducted in Sungai Gayung Kiri Village in October 2020. The aim of the study was to identify the composition and proportion of the main, by-catch and discarded catches in gombang fishing gear. The method used in this study is a survey method, namely by interviewing and direct observation in fishing waters, identifying species and counting the number of each species caught by gombang fishing gear. Data analysis used descriptive statistics which were tabulated in the form of tables and graphs. The results showed that pepay shrimp (Sergestes similis) was the main or most dominant catch caught in gombang fishing gear, which was 65.91%. The largest percentage of bycatch is beliak mato (Ilisha elongata) at 0.18%, and the percentage of discharge, namely striped crab (Brachura lannaeus) is 0.04%.

Abstract

Sharks are predatory animals that dwell near coral reefs and swim at the ocean's bottom. Since the inclusion of many shark species in CITES Appendix II status in 2013, shark groups have become a global issue. This is owing to shark fishing's high exploitation, both as a target capture and as bycatch. It is divided into eleven fisheries management areas, one of which is WPPNRI 572, according to the Regulation of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number 18/PERMEN-KP/2014 concerning the State Fisheries Management Area of the Republic of Indonesia, hereinafter abbreviated as WPPNRI. The Indian Ocean waters west of Sumatra, as well as the Sunda Strait, are included in this area. Because it faces the high seas, notably the Indian Ocean, Sumatra's west coast is a key area of the Indonesian sea. The city of Sibolga is strategically important as one of the key entry points for utilizing the potential of western Sumatra's waters. This study was place during August and September of 2021. The goal of this study was to identify sharks landed through TPI Sibolga City in North Sumatra Province, describe their morphology and morphometrics, and describe their conservation status using IUCN and CITES criteria. Squalus chloroculus, Nebrius ferrugineus, Carcharhinus brevipinna, Carcharhinus falciformis, Carcharhinus melanopterus, Carcharhinus sorrah, Rhizoprionodon acutus, Rhizoprionodon oligolinx, and Sphyrna lewini were among the 310 sharks successfully landed in the TPI, according to the study's findings. The overall length variable has the strongest tendency, according to the results of the Principal Component Analysis Scree Plot. C. brevipinna, C. falciformis, C. melanopterus, C. sorrah, and T. obesus are shark species with comparable morphometric features. According to the IUCN, the conservation status of S. lewini is Critical or Threatened (EN). The status of N. ferrugineus is Very Vulnerable (VU). Near Threatened (NT) status for S. chloroculus, C. brevipinna, C. falciformis, C. melanopterus, C. sorrah, and T. obesus. Less Worrying Status was assigned to R. acutus and R. oligolinx (LC). While the trading status of sharks based on CITES, particularly C. falciformis, C. melanopterus, and S. lewini, are included in the Appendix II list, which denotes species that are not threatened with extinction but could be affected if trade continues without regulation.

Abstract

This research was conducted in September 2019 in Sinaboi Waters, Rokan Hilir Regency, Riau Province. This study aims to analyze the technical and financial aspects of catching mantis shrimp (Harpiosquilla raphidea) in drift bottom fishing gear. The method used is survey method and case study. The fishing fleet used is 1 ship with a weight of 3 GT, which has a 27 HP propulsion engine. The results of the technical analysis, the main catch of the bottom drift net fishing gear is mantis shrimp using bait and obtained an upper hanging ratio of 0.55; hanging ratio down by 0.45 and shortening by 55%. The results of the calculation of business feasibility analysis show the total investment value of the fishing business is Rp.46,622,000 with a BCR value of 1.2, an FRR value of 39.53%, and a PPC value of 2.5 which means the time required by fishermen to The payback period is 2 years 5 months. Therefore, it can be concluded that the fishing effort is feasible to run and develop

Abstract

When filling supplies at sea, it is not only troll line fishing vessels that fill up supplies at PPS Bungus but also other fishing vessels. The large number of fishing fleets filling up fishing supplies causes queues that can affect the cost of mooring ships. To find out how efficiency the time of filling supplies at sea troll line fishing vessels is and the factors that influence it, this study was conducted. The method used is a survey method of 20 sample ships that carry out fishing activities. From the results of the study, it was found that the efficiency level of filling time for troll line fishing boats ranged from 74.22% to 89.01% with an average of 82.31%, which means efficiency. The size of the efficiency level when filling fishing supplies is very dependent on the length of the effective time used. The amount of effective time is influenced by the number of supplies of clean water (x1), fuel (x2), ice cubes (x3), and the number of actors filling fishing supplies (x4), in the form of multiple regression equation Y = 58,5700 + 0.0363x1 + 0 .0488x2 + 0.1652x3 – 9.5800x4. The efficiency level of filling time for fishing supplies can still be improved by reducing wasted time
