THE RELATIONSHIP BETWEEN LENGTH AND WEIGHT OF MACKEREL FISH (Rastrelliger sp.) AT THE FISH AUCTION PLACE (TPI) GUDANG LELANG, TELUK BETUNG, LAMPUNG

Abstract

The fishing centers that can be utilized in Lampung Province is the TPI Gudang Lelang Market. The catch from fishermen around TPI Gudang Lelang consists of economically valuable fish such as hairtail, scads, and mackerel fish. Fishermen at TPI Gudang Lelang can produce catches of approximately 90-100 tons per month. The objective of this independent project is to determine the weight and length of the mackerel fish (Rastrelliger sp) caught at TPI Gudang Lelang and to analyze the relationship between the length and weight of the Kembung fish at this location. This independent project was conducted from September to December 2022, located at TPI Gudang Lelang, Teluk Betung, Bandar Lampung. The method employed was direct observation in the field. The subjects of the study were the length and weight of the Kembung fish. The mackerel fish (Rastrelliger sp) found at TPI Gudang Lelang have an average body length of 19.6 cm and an average weight of 0.116 grams. The relationship between the length and weight of the mackerel fish, analyzed using regression analysis, yielded a value of (b) 2.84, indicating that the growth in length does not correspond with the growth in weight (with length growth being more dominant than weight growth). Additionally, the value of (R²) is 0.607, suggesting a weak relationship between the length and weight of the mackerel fish.
