Estimates of Marine Mammal, Sea Turtle, and Seabird Mortality in the California Drift Gillnet Fishery for Swordfish and Thresher Shark, 1996–2002 [PDF]

open access: yes, 2004
Estimates of incidental marine mammal, sea turtle, and seabird mortality in the California drift gillnet fishery for broadbill swordfish, Xiphias gladius, and common thresher shark, Alopias vulpinus, are summarized for the 7-year period, 1996 to 2002 ...

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

open access: yesEconomic 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

Gillnet catchability of brown trout Salmo trutta is highly dependent on fish size and capture site

open access: yesFauna Norvegica, 2019
Use of experimental gillnet fleets is common both in scientific studies of fish populations and in fish sampling for management purposes. Fish catchability may vary considerably with fish and gillnet mesh size, and catches obtained by gillnet fleets ...

Socioeconomic characteristics of payang seine (lampara) and driftnet fisheries in West Sumatra, Indonesia [PDF]

open access: yes, 2000
A proportionate random sample survey of 10 percent of the driftnet and Payang seine fishers in West Sumatra was carried out in 1998. A total of 45 driftnet and 66 lampara fishers were interviewed to obtain socioeconomic data on the fisheries.

The Use of Gillnets for Estimation of Fish Stocks [PDF]

open access: yesJournal of Animal and Veterinary Advances, 2010
In this research it has been targeted to estimate fishable stocks of Karakaya Dam Lake (in Turkey) by using fishing with gillnets method that had been suggested as an alternative method for estimating fish stocks. Productivity per hectare in the dam lake and the amount of fishable stocks has been calculated to be 13.67 kg ha-1 and 312.005 kg year-1 ...

Discard Survival of Thornback Ray (Raja clavata), Undulate Ray (Raja undulata) and Small‐Eyed Ray (Raja microocellata) in Northeast Atlantic Inshore Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Quantifying discard survival of species is crucial for effective fishery management. Electronic tags and visual health assessments were used to estimate postrelease survival of commercially caught thornback ray (Raja clavata), undulate ray (Raja undulata) and small‐eyed ray (Raja microocellata) from Northeast Atlantic inshore fisheries ...

A Changing Gulf of Maine: Investigating the Role of Benthic Water Temperature in Determining the Timing of Spiny Dogfish (Squalus acanthias) Arrival and Departure in the Gulf of Maine [PDF]

open access: yes, 2017
Spiny Dogfish (Squalus acanthias) is a highly migratory elasmobranch that undergoes annual migrations along the East Coast of the United States. Spiny dogfish have been studied extensively on the West Coast, but little information currently exists on the

On Selectivity Curve of Gillnet

open access: yesNIPPON SUISAN GAKKAISHI, 1971
The preceding paper showed that the mesh selectivity, i.e. relative efficiency, of gillnet was expressed as a function of the ratio of mesh size m to body length l in certain ranges of mesh size and length, and that the application of the above method to McCOMBIE and FRY's, and ISHIDA's data gave different master curves according to the groups of ...

Gillnet fishing characteristics in Franciscana Management Areas

open access: yes, 2022
The main threat to franciscanas (Pontoporia blainvillei) is the incidental catches in gillnets. Given the variety of this fleet and the fishing communities in Brazil, the aim of this chapter is to characterize the social-economic, socioenvironment, and ethno-environment aspects of the gillnet activity in the Franciscana Management Areas (FMA) II and ...

Factors Influencing the Stocking of Juvenile Pikeperch (Sander lucioperca)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Predator species of fish play crucial roles in ecosystem balance through top‐down control, a mechanism frequently exploited in biomanipulation to stock predator species. Juvenile pikeperch (Sander lucioperca) were stocked (n = 52,887) in spring 2023 and 2024 and autumn 2023 to compare stocking efficiency between Recirculation Aquaculture ...
