Post-moratorium Tiger Prawn (Penaeus monodon) Double Rig Trawl catch in the Arafura Sea
2024
Overview
In 2021, trawling operations in the Arafura Sea were permitted to resume after a moratorium of several years. Therefore, this research aimed to provide up-to-date information to support sustainable tiger prawn management. Data were collected through field surveys and fishing trips aboard a double rig bottom trawler over a one-year fishing cycle (12 months) from February 2023 to January 2024. The monthly tiger prawn catch volume and size composition were recorded and analysed descriptively. The average daily catch was highest in November (803 kg/day) and lowest in May and June (86 kg/day and 64 kg/day, respectively). Tiger prawn weight range was 15-107 g. The most frequently caught size classes were large T-18 (mean 83.3 g/prawn, total volume 13,380 kg) and small T-100 (mean 15 g/prawn, total volume 861 kg). The predominant processed (headless) prawn size classes were L (1,488 kg) and S (614 kg). From December to January, the percentage of small prawns (T-60 to T-100, S and SS classes) increased significantly; therefore, a closed fishing season covering these months is recommended.
