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.

Comparative visual ecophysiology of mid-Atlantic temperate reef fishes

open access: yesBiology Open, 2013
Summary The absolute light sensitivities, temporal properties, and spectral sensitivities of the visual systems of three mid-Atlantic temperate reef fishes (Atlantic spadefish [Ephippidae: Chaetodipterus faber], tautog [Labridae: Tautoga onitis], and ...

Searching speeds and the energetic feasibility of an obligate whale-scavenging fish [PDF]

open access: yes, 2005
Two recently published models reach opposite conclusions on the energetic feasibility of a scavenging fish that specialises oil whale carcasses. We argue that the key difference between these models lies in their estimate of the likely searching speed of

Fish landings and Oman shelf area

open access: yesJournal of Agricultural and Marine Sciences, 2016
Data from five field surveys carried out along the shelf in the 20-250m depth range and historical data on artisanal fishery were analyzed. A positive linear relationship between the demersal fish biomass and the shelf area was pronounced for a certain ...

Using hydrodynamics to modify fishing performance of a demersal fishing gear

open access: yesFisheries Research, 2023
This study demonstrates how hydrodynamics can be used to influence the fishing performance of towed demersal fishing gears. Sea trials are performed in the sea star fishery to show how modifications to the gear design alter the hydrodynamics of the turbulent wake and consequently affect the catching performance of trawl gears.

A taste of the deep-sea: The roles of gustatory and tactile searching behaviour in the grenadier fish Coryphaenoides armatus [PDF]

open access: yes, 2007
The deep-sea grenadier fishes (Coryphaenoides spp.) are among the dominant predators and scavengers in the ocean basins that cover much of Earth's surface. Baited camera experiments were used to study the behaviour of these fishes.

DNA barcoding and misidentification of some marine fish species in Nigerian industrial trawl fishery

open access: yesScientific African, 2023
Identification of marine fishes across their geographical distribution is based primarily on morphological features. The ability of marine fishes to adapt to environmental changes sometimes leads to morphological differences that might give rise to wrong

Demersal fish in Icelandic waters

open access: yes, 2021
A sudden increase in population size and distribution around Iceland took place in several species in 2000-2010. What they have in common is that Iceland is placed at the northern border of their geographic range making the susceptible to environmental fluctuations.
