Abstract

The longline fishing gear in the Bangsal Aceh District is a secondary fishing gear from the pengerih fishing gear, the Bangsal Aceh anglers use the longline fishing gear when they are free or when anglers only want to use it. This study aims to determine the construction of longline fishing gear and determine the basic composition of longline catches using bait that is often used. The research method used is a survey method. The data collected starts from supplies, ship condition, condition of fishing gear, data on fish species, fish weight, and the number of individual fish, which are then analyzed by calculating the effort of the hook rate, and the catches obtained. Then analyzed descriptively by defining the main catch and bycatch. From the results of the research conducted for two weeks, the catch consisted of three types, namely giant catfish, sagor, and stingrays. Stingrays were the heaviest fish weighing 57.8 kg (80.38%), followed by giant catfish with 13.6 kg (18.9152%), and sagor with 0.5 kg (0.69541%). Meanwhile, according to individuals, the most commonly found fish were 11 giant catfish (64.7%), followed by 5 stingrays (29.4118%), and 1 sagor (5.88235%).

Abstract

The problems that are often experienced when cultivating goldfish are diseases caused by pathogens that attack cultivated fish. The cause of disease in fish is caused by interactions between fish, pathogens and their habitat environment that can cause death in fish. The solution to this problem is to provide a phytoimmunostimulant derived from mango leaves (Mangifera indica). The purpose of this study was to determine the effect of mango leaves on the hematology and physiology of common carp. This research was conducted in January-April 2022. The method used in this research is an experimental method by comparing data. Parameters observed were total erythrocytes, hemoglobin, hematocrit, blood glucose, absolute body weight growth, survival rate, and water quality. Based on the research that has been done, it can be concluded that the addition of 1.5% mango leaf powder into fish feed as a phytoimmunostimulant affects the hematological and physiological effects of common carp. Common carp treated with phytoimmunostimulants in fresh water had higher mean values ​​(total erythrocytes 1.75x106 cells/mm3, hematocrit 33.66%, and hemoglobin 8.13 g/dL) compared to data in brackish water (total erythrocytes 1.54x106 cells/mm3, hematocrit 30.66%, and hemoglobin 7.76 g/dL).

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

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.
