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.

High-Resolution Acoustic Cameras Provide Direct and Efficient Assessments of Large Demersal Fish Populations in Extremely Turbid Waters

open access: yesApplied Sciences, 2021
Monitoring fish species populations in very turbid environments is challenging. Acoustic cameras allow work in very poor visibility but are often deployed as a fixed observation point, limiting the scope of the survey. A BlueView P900-130 acoustic camera

Feeding Habit-Specific Heavy Metal Bioaccumulation and Health Risk Assessment of Fish in a Tropical Reservoir in Southern China

open access: yesFishes, 2023
Dietary uptake is well known as the predominant pathway of heavy metal bioaccumulation in organisms. Our study used a typical tropical reservoir and fish as a modeling system to test the hypothesis that feeding habits and living habitats significantly ...

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.

Cadmium accumulation in coastal demersal fish [PDF]

open access: yesMarine Ecology Progress Series, 2006
The hepatic Cd burden, measured on 291 individuals of 4 species of demersal fish (Gadus morhua, Reinhardtius hippoglossoides, Hippoglossoides platessoides, and Raja radiata), is 2 to 5 times higher in fish from the open Gulf of St. Lawrence than in fish from the St. Lawrence Estuary, 600 km landward. The higher Cd burden in the open Gulf is not related

Trophic redundancy in benthic fish food webs increases with scarcity of prey items, in the Southern Baltic Sea

open access: yesFrontiers in Marine Science, 2023
Bottom trawling is one of the main pressures on benthic ecosystems, directly impacting the targeted species and physically disturbing the seabed and the benthic invertebrate communities, in turn indirectly impacting benthivorous fish and the entire ...

Demersal Fish Assemblages in NE Atlantic Seagrass and Kelp

open access: yesDiversity, 2020
Global fisheries are in decline, calling for urgent evidence-based action. One such action is the identification and protection of fishery-associated habitats such as seagrass meadows and kelp forests, both of which have suffered long-term loss and ...

Evaluating Sampling Designs for Demersal Fish Communities [PDF]

open access: yesSustainability, 2018
Fish communities play an important role in determining the dynamics of marine ecosystems, while the evaluation and formulation of protective measures for these fish communities depends on the quality and quantity of data collected from well-designed sampling programs.
