Cleaner Fish Labroides dimidiatus Presence Does Not Indirectly Affect Demersal Zooplankton

open access: yesFrontiers in Marine Science, 2022
Coral reef mutualisms involve complex trophic ecological relationships that produce indirect effects. Excluding mutualistic cleaner fish Labroides dimidiatus from reefs indirectly increases the abundance of many fishes and reduces demersal stages of ...

Taxonomic distinctness of demersal fishes of the California current: moving beyond simple measures of diversity for marine ecosystem-based management. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Large-scale patterns or trends in species diversity have long interested ecologists. The classic pattern is for diversity (e.g., species richness) to decrease with increasing latitude.

Trophic Ecology of Deep-Sea Megafauna in the Ultra-Oligotrophic Southeastern Mediterranean Sea

open access: yesFrontiers in Marine Science, 2022
The trophic ecology of fourteen species of demersal fishes and six species of demersal decapod crustaceans from the continental slope and rise of the Southeastern Mediterranean Sea (SEMS) was examined using stable isotope analysis. Mean δ13C values among

DEMERSAL FISHING ANALYSIS OF KUPANG BAY [PDF]

open access: yesMarine Research in Indonesia, 1970
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]

open access: yesPLoS ONE, 2010
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.
