Jurnal Bluefin Fisheries Volume 3 Number 1 (2021) presents five scientific articles covering fisheries biology, fish processing technology, shelf-life estimation of fishery products, and fishing gear productivity.

The first article examines the secondary sexual characteristics of tude batu fish (Selar boops) from Bitung waters using morphometric and discriminant analyses to distinguish male and female fish.

The second article investigates the processing stages and quality characteristics of frozen yellowfin tuna (Thunnus albacares) loins, including cold chain implementation, yield determination, and quality assessment of raw materials and finished products.

The third article discusses the shelf-life estimation of liquid-smoked tandipang fish in Bitung City, focusing on smoking treatments and product storage stability.

The fourth article investigates the productivity of modified bottom longline fishing gear, known as Rawai Dasar Layangan (RDL), operated in the waters of the Lembeh Strait, Bitung, North Sulawesi.

The fifth article describes the diversification of smoked tandipang fish into chili sauce packaged in jars, including product quality and shelf-life evaluation.

Collectively, these articles contribute to the development of marine and fisheries science and technology, particularly in fisheries resource management, fishing technology, quality improvement, and diversification of processed fishery products.
