Size-related differences in power production and swim speed duration may contribute to the observed deficit of nursing calves in relation to lactating females killed in sets by tuna purse-seiners in the eastern tropical Pacific Ocean (ETP). Power production and swim-speed duration were estimated for northeastern spotted dolphins (Stenella attenuata), the species (neonate through adult) most oft...

The waters of the Makassar Strait South Sulawesi, where various Purse Seine vessels operate, have characteristics very high biodiversity, strength strong ocean currents, and temperature cultural Bugisness fishermen. It is necessary to design a purse seine ship that perfectly matches designs traditional ships operating in Sulawesi so far. This research aims create vessel under 100GT with Interna...

Bait usage in the KwaZulu-Natal recreational and commercial linefishery was assessed using historic fisher-derived data and current sales records of bait providers.
