Fishery discards: Factors affecting their variability within a demersal trawl fishery [PDF]

, 2012
Discards represent one of the most important issues within current commercial fishing. It occurs for a range of reasons and is influenced by an even more complex array of factors.

Bycatch of crustacean and fish bottom trawl fisheries from southern Portugal (Algarve)

Scientia Marina, 2008
As part of two research projects for analysing bycatch and discards, we quantified catch composition, catch rates, bycatch and discards in two important commercial bottom trawl fisheries (crustacean and fish trawls) off the southern coast of Portugal ...

Spatiotemporal patterns of catch and discards of the Israeli Mediterranean trawl fishery in the early 1990s: ecological and conservation perspectives

Scientia Marina, 2011
The spatiotemporal patterns of discards and catch composition of Israeli trawlers were examined using a 4-year (1990-1994), 324 haul dataset. Haul depth was found to be the main grouping variable for hauls, although significant seasonal differences were ...

Every Fish Counts: Challenging Length–Weight Relationship Bias in Discards

Fishes, 2023
Bycatch is a significant issue in global fisheries and understanding the length–weight relationships (LWR) of fish species can provide valuable insights for stock assessment and management efforts.

The use of demersal trawling discards as a food source for two scavenging seabird species: a case study of an eastern Mediterranean oligotrophic marine ecosystem

Avian Research, 2018
Background The banning of fisheries discards by imposing an obligation to land unwanted catch constitutes a key point of the Common Fishery Policy reform proposed by the European Commission.

DISCARDED NYLON FISHING NETS AS FIBRE REINFORCEMENT IN CEMENT MORTAR [PDF]

WIT Transactions on Ecology and the Environment, 2018
This work builds on an idea of utilizing fibres cut from waste fishing nets for fibre reinforcement of concrete. An experimental investigation of waste fishing net polyfilament fibres of nylon 6 is reported. Differential Scanning Calorimetry confirmed the net to be nylon 6.

Preliminary evaluation of landings and discards of the Turkish bottom trawl fishery in the northeastern Aegean Sea (eastern Mediterranean)

Scientia Marina, 2014
This short-term study on commercial discards was carried out in fishing grounds around Gökçeada Island in the northeastern Aegean Sea, a geographic area where fisheries information is rather limited.

Gulls as Indicators of Environmental Changes in the North Atlantic: A Long-Term Study on Berlenga Island, Western Portugal

Diversity, 2023
In recent decades, the breeding populations of the yellow-legged gull Larus michahellis (YLG) have increased significantly, primarily due to the increase in open refuse dumps and discards from fisheries.

Impacts of fisheries on seabird communities

Scientia Marina, 2003
Long-line by-catch of albatrosses and petrels may soon lead to species extinctions. Set-net bycatch has caused major reductions in certain seabird populations. Some fisheries may decrease numbers of seabirds by reducing abundance of prey-fish.
