Does Lobster Trap Bait Influence the Maine Inshore Trap Fishery?
North American Journal of Fisheries Management, 2002Abstract The potential role of lobster trap bait as a significant food subsidy contributing to unprecedented recent increases in abundance and landings of the American lobster Homarus americanus is seldom considered seriously outside the fishing community.

Aerial drone technology can assist compliance of trap fisheries
Fisheries Management and Ecology, 2020AbstractIllegal fishing is a global issue that threatens the viability of fishing industries and biodiversity conservation. Management agencies typically use on‐ground surveillance to monitor and minimise illegal fishing practices, the efficacy of which may be enhanced by integrating emerging remote sensing technology.

The 'fishery' in South Africa's remaining coastal stonewall fish traps
African Journal of Marine Science, 2009Ancient stonewall fish traps along the southern coast of South Africa, known locally as ‘vywers’, have both cultural and historical significance. Most have been degraded through neglect. Only two sets of vywers are actively maintained and fished, but without legal sanction. We surveyed historical and present-day fishing techniques and catches in the

Social-ecological traps in reef fisheries
Global Environmental Change, 2011[Extract] There is a long history of research on social traps, which are situations where individuals or even whole societies "get started in some direction or some set of relationships that later prove to be unpleasant or lethal and that they see no easy way to back out or to avoid" (Platt, 1973, p. 641).

The habitats exploited and the species trapped in a Caribbean island trap fishery
Environmental Biology of Fishes, 2004We visually observed fish traps in situ to identify the habitats exploited by the U.S. Virgin Islands fishery and to document species composition and abundance in traps by habitat. Fishers set more traps in algal plains than in any other habitat around St. John. Coral reefs, traditionally targeted by fishers, accounted for only 16 % of traps.

Bait Improvement For Swimming Crab Trap Fisheries
2011One of the most commonly cited problems regarding age determination in crustaceans is the absence of any calcified structures containing growth rings. The question addressed by this study is: do the zygocardic, prepyloric and pyloric ossicles of the gastric mill of decapod crustaceans contain any record of growth?

Trap fisheries for squid and their impact on spawning
South African Journal of Marine Science, 1998The squid trap is an artisanal type of fishing gear widely used in the Gulf of Thailand and along the Andaman coast. In 1994 the total catch of cephalopods by Thailand was 144 436 tons, of which 5% was fromsquid traps. The trap is covered by coconut fronds and set from 4 to >40 m deep, hanging above the sea bottom with the entrance facing upwards.

Mesh selectivity in the New South Wales demersal trap fishery
Fisheries Research, 2003Abstract Observers onboard commercial trap vessels quantified the sizes of fish in the discarded and retained catch for the major species in the New South Wales (NSW) demersal trap fishery. Selectivity ogives were calculated for the two mesh types used in the fishery, 50 mm hexagonal wire mesh and 50 mm ×75 mm welded mesh, by comparing ...

Fishery-independent trap surveys of lobsters (Homarus americanus): design considerations
Fisheries Research, 2003Abstract Trap surveys for lobsters were conducted off northern Cape Breton in 1994 and 1995 outside the commercial lobster fishing season. These pilot surveys used a stratified random design based on depth and alongshore location. Comparisons of end trap and middle trap catch rate indicates that traps were not saturated, and that the distance of trap

Have changes in selectivity masked recruitment declines in crustacean trap fisheries?
Fisheries Research, 2003In the Tasmanian rock lobster assessment model, as in many other assessment models, selectivity is treated as a fixed effect. The actual size composition in the population is estimated by dividing the survey catch in each size class by the size-specific selectivity.
