Abstract: Bang tawa Sub-district, located in Nong Jik District, Pattani Province, is known as an important fishing ground for "Pla Kulao" (Fourfinger threadfin). The fish caught in this area are primarily processed for salting. However, there is a lack of statistical data on the quantity of Fourfinger threadfins in this area and their post-harvest quality. Hence, this research aims to study the quantity and quality of catches, as well as their storage, during the fishing season. The study revealed that the catch quantity of Fourfinger threadfin in the Bang tawa Sub-district amounted to 8,366.6 kilograms/year. The highest catch quantity was recorded in January, with 2,013.6 kilograms/year. The physical and chemical quality of Fourfinger threadfin with three sizes was studied, and the fish were classified into three weight ranges. Samples were collected every 3 months, namely in January, April, July, and October. The average protein content for each weight range was as follows: 19.97%, 22.79%, 24.35%, and 22.99%, respectively. The 1-2 kilograms Fourfinger threadfin showed the highest protein content in every month (p<0.05). For each weight range, the average fat content was 2.52%, 2.20%, 2.82%, and 2.84%, respectively. Additionally, the fat content in female Fourfinger threadfin was 1.32 times higher than that in males. The TVB-N value, which indicates fish deterioration, had the highest value of 21.51 (mg/100 g)in April. When analyzing the correlation between chemical properties and freshness score of Fourfinger threadfin, it was found that physical characteristics were positively correlated with chemical properties (p<0.01). Regarding the preservation of fresh Fourfinger threadfin for salted fish production, chilling (10±2 °C) allowed preservation for 3 days, whereas freezing (-18±2 °C) extended preservation beyond 30 days.
