Pengaruh Waktu Terhadap Hasil Tangkapan Rajungan (Portunus Pelagicus) Menggunakan Bubu Bentuk Kubah Di Pesisir Waiheru, Teluk Ambon Dalam

Abstract

The aim of this research is to see the effect of different fishing times on the catch of blue swimming crab (Portunus pelagicus) using dome-shaped traps on the Waiheru coast, Inner Ambon Bay. The research was conducted on the Waiheru waters, Inner Ambon Bay, Ambon City, in March 2023. The data collection method used field tests to obtain data on the number of catches (individuals) and weight of blue swimming crabs (grams) caught during the day and night. The data were then analyzed using the t test on the two time units used. The results showed that the number of blue swimming crabs catches was different between day and night, with the highest number at night (62). The t test also showed that there was a difference in the weight of blue swimming crab caught at both times, where the catch at night was higher (8622.4 gr) than during the day.
