CONSTRUCTION ANALYSIS OF BOTTOM GILLNET AS AN ALTERNATIVE TO BOTTOM TRAWL IN PEKALONGAN WATERS [PDF]

Russian Journal of Agricultural and Socio-Economic Sciences, 2019
A bottom trawl is a fishing tool that is not recommended by the government to capture demersal fish resources in Pekalongan waters. Therefore, a bottom gillnet is an alternative substitute for bottom trawl fishing gear in catching demersal fish.

Does nature shape risk preferences? Evidence from Chile, Norway, and Tanzania

Economic Inquiry, Volume 63, Issue 2, Page 568-590, April 2025.
Abstract Does exposure to a more risky environment affect risk preferences? Going beyond single‐case study evidence, we report results from five surveys conducted in three countries and link this with administrative data to study whether a link between exposure and preferences is detectable and widespread. We find no evidence for endogenous preferences

Recreational boat fishing pressure on fish communities of the shelf and shelf break of Faial and Pico Islands (Azores Archipelago): implications for coastal resource management [PDF]

Acta Ichthyologica et Piscatoria, 2013
Background. Several studies have highlighted the negative potential of recreational boat fishing to put pressure on coastal fish species and in particular on those that are vulnerable.

Bioaccumulation modelling and sensitivity analysis for discovering key players in contaminated food webs: the case study of PCBs in the Adriatic Sea [PDF]

, 2015
Modelling bioaccumulation processes at the food web level is the main step to analyse the effects of pollutants at the global ecosystem level. A crucial question is understanding which species play a key role in the trophic transfer of contaminants to ...

Assessing Risk for Bycatch and Byproduct Species Using a Modified Sustainability Assessment for Fishing Effects (SAFE) Approach

Fish and Fisheries, EarlyView.
ABSTRACT Central to ecosystem‐based fisheries management is ensuring the sustainability of bycatch and byproduct species. However, the sustainability of these species is difficult to assess as the lack of information limits the use of traditional stock assessment methods.

Fish landings and Oman shelf area

Journal 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 ...

Geolocation of a demersal fish (Pacific cod) in a high-latitude island chain (Aleutian Islands, Alaska)

Animal Biotelemetry, 2023
Background Fish geolocation methods are most effective when they are customized to account for species behavior and study area characteristics. Here, we provide an example of customizing a hidden Markov model (HMM) for reconstructing movement pathways of

Nonstationary Responses of Demersal Fishes to Environmental Variations in Temperate Waters of the Northwestern North Pacific under a Changing Climate

Fishes, 2021
Although nonstationarity in marine ecosystems has attracted great attention, the nonstationary responses of demersal fishes to environmental variations induced by the changing climate are still not well understood.

Fishes of the deep demersal habitat at Ngazidja (Grand Comoro) Island, Western Indian Ocean [PDF]

, 2006
Underwater observations of the coelacanth, Latimeria chalumnae Smith, 1939, from a research submersible provided opportunities to study the deep demersal fish fauna at the Comoro Islands. The demersal habitat in depths of 150–400 m at the volcanic island

Recompression Improves Release Success in Pollack (Pollachius pollachius): A Step Towards Assessing Post Release Mortality in a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT The recreational fishery for pollack (Pollachius pollachius) in the northeast Atlantic is impacted by the species' high sensitivity to barotrauma. When captured at depth and brought to the surface, gas expansion within the peritoneal cavity can cause a variety of injuries and hinder release.
