Abstract

The waters of Bitung, located in North Sulawesi Province, have long been known for their rich underwater biodiversity, specifically unique and exotic creatures. They are a potential demersal fishing ground for coastal fishermen in Bitung City. However, information on demersal fishing grounds is limited, so it is necessary to conduct research and map demersal fishing grounds in Bitung waters. This study aims to obtain data on the geographical position of demersal fishing areas in Bitung waters to be mapped into a map of demersal fishing areas in Bitung waters and determine the types of catches from bottom fishing rods. Data was collected directly by following demersal fishing operations on the training ship FV. Coelacanth. The data were analyzed using survey methods and direct observation, which is an effort to collect information directly from a part of the population that is considered a specified population and has the nature of authentication or checking of existing theories. The study's results obtained geographical data on demersal fishing areas in Bitung waters at (1) 10°23.447' N, 125°06.934' E (Suar Batu Kapal area),, (2) 10°23.483' N, 125°09.567' E (Karang Tanjung Merah area) (3) 10°23.283' N, 125°10.852' E (Batu Angus Area), (4) 10°30.393' N, 125°15.392' E (Menara Lampu Hijau Area), and (5) 10°32.706' N, 125°18.105' E (Dua Pulau area). The primary catches of bottom fishing consist of fish species: grouper, snapper, trevally fish, Gora fish, emperor fish and parrot fish.

Abstract

This research was carried out because the information related to the size of fish capture and the status of exploiting S. boops was still very little, especially in the waters around Bitung. The appropriate size of capture and exploitation status can be used as a reference to assess whether the utilization of S. boops resources in the waters around Bitung is in accordance with the sustainable management guidelines for fish resources. This study aims (1) to get the size of the first caught fish (Lc); (2) get the size of fish first cooked gonad (Lm); (3) obtain S. boops business status. The sampling of fish was obtained from the Bitung coastal fishermen who landed his catch at the Bitung Ocean Port. Retrieval of fish sample data was carried out from February 2016 to January 2017 with a total samples 1,659 using the survey method. The results showed that the size of first captured 15.10 cm FL while the size of the first matured obtained 16.30 cm FL. The status of exploitation based on the comparison of Lc and Lm parameters that percentage of matured and the SPR value categorized as overfishing.

Abstract

Sumberdaya kelompok ikan Layang di perairan Bitung memiliki nilai ekonomis sehingga perlu dilakukan pengelolaan berdasarkan nama spesies ikan yang valid. Salah satu ciri khusus perikanan tangkap di Indonesia adalah multispesies dan multigear dan dalam pencatatan ikan hasil tangkapan hanya menggunakan nama kelompok ikan, sehingga untuk satu nama kelompok ikan dapat terdiri dari beberapa spesies ikan. Penelitian ini bertujuan melakukan identifikasi spesies ikan layang yang tertangkap di perairan Bitung secara genetik untuk mendapatkan spesies yang valid. Untuk mendapatkan karakteristik genetik dan filogenetik dari 4 sampel ikan layang dilakukan ekstraksi DNA, Polymerase Chain Reaction (PCR), penyuntingan DNA dan analisis filogenetik dan evolusi molekuler menggunakan program MEGA versi X. Hasil penelitian mendapatkan bahwa secara genetik ikan layang anggur Bitung merupakan spesies Decapterus smithvanizi dan ikan layang biru dengan ukuran kecil, sedang dan besar merupakan spesies Decapterus macarellus. Filogenetik D. smithvanizi Bitung memiliki jarak kekerabatan yang dekat dengan jenis yang sama dari perairan Philipina, sedangkan D. macarellus Bitung memiliki kekerabatan yang dekat dengan jenis yang sama dari perairan Vietnam. Perlu dilakukan kajian aspek biologi D. smithvanizi untuk melengkapi informasi yang belum tersedia saat ini.

Abstract

One source of marine pollution can be caused by the operational activities of fishing vessels. This research aims to identify the type and amount of waste originating from fishing vessels. Data collection was conducted at Bitung Ocean Fishing Port during November-December 2023 by purposive sampling. The waste that has been collected, sorted and weighed. Data were analysed using descriptive quantitative. The waste generated by fishing vessels consists of two types, namely organic and inorganic waste. Organic waste consists of food waste and kitchen waste, while inorganic waste consists of 70% plastic, 12% processed wood, 10% glass, 6% clothing or cloth, and 1% metal and rubber. Organic waste is disposed of directly into the sea, while inorganic waste is collected in storage containers for later disposal on land. There is a need for more action in fishery vessel waste management, such as training in recycling that can generate economic benefits, in an effort to reduce waste from fishing vessels.
