Water Quality Survey in the Waters of Bangka to Support the Squid Fisheries Refugia.

Abstract

Bangka waters are part of the Sunda Shelf (Sunda Shelf) so that these waters are included in shallow waters where the average water depth is 30 m. Water depth is a very influential factor in the existence of squid and in general squid are found living in shallow demersal waters, close to the coast, in seagrass and coral ecosystems to a depth of 700 m (Jereb & Roper, 2010). Several studies show that the catch of squid in the waters of the Karimata Strait to the Java Sea is mostly caught in waters with warmer temperatures ranging from 24,8 to 32,1 °C, where U. chinensis squid are mostly found in Bangka waters, generally live in the optimum temperature range of 21–29 °C (Prasetyo et al. 2014).
