DEMERSAL FISHING ANALYSIS OF KUPANG BAY [PDF]
Study on demersal fish in Kupang bay was carried for 6 months, from July 2002 to December 2002. Sampling was conducted twice a month at the ten-selected locations within the bay using different fishing gears such as gill net, bottom logline, hand line and traps.

Diet of two large sympatric teleosts, the ling (Genypterus blacodes) and hake (Merluccius australis). [PDF]
Ling and hake are tertiary consumers, and as a result both may have an important structuring role in marine communities. The diets of 2064 ling and 913 hake from Chatham Rise, New Zealand, were determined from examination of stomach contents.

The effects of fishing on demersal fish communities of the Scotian Shelf [PDF]
Since the 1970s, average individual weight of commercially targeted demersal fish on the Scotian Shelf (Canada) decreased by 51% on the eastern shelf and by 41% on the western shelf. For both systems, the integrated community size spectrum showed long-term declines in proportions of large fish and survey cpue of most targeted species.

The effect of fishing on demersal fish community dynamics: an hypothesis [PDF]
Fishing acts like a predator; it alters the extent of competition and allows the coexistence of competitive species. To test this hypothesis, several component elements are addressed. The variability of biomass in demersal fish communities is analysed to seek evidence that biotic interactions play a role in community dynamics.
