Fishery Discards: Factors Affecting Their Variability within a Demersal Trawl Fishery
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. We address this issue by examining the data collected within the Danish discard observer program and describe the factors that influence discarding within the Danish Kattegat demersal fleet over the period 1997 to 200...
متن کاملLimited mid-water scavenging of trawl discards
The consumption or scavenging of ¢sh in the water column at depths from 75 to 275m in Algarve (southern Portugal) trawl ¢shing grounds was evaluated. Longlines were used to suspend baits throughout the water column while electric ¢shing reels were used to simulate sinking discards. Eighteen species were caught, with higher catch rates near the surface than near the bottom. However, scavenging r...
متن کاملCascading ecological effects of eliminating fishery discards
Discarding by fisheries is perceived as contrary to responsible harvesting. Legislation seeking to end the practice is being introduced in many jurisdictions. However, discarded fish are food for a range of scavenging species; so, ending discarding may have ecological consequences. Here we investigate the sensitivity of ecological effects to discarding policies using an ecosystem model of the N...

متن کاملA long term (1949-2010) study of catch and effort in Israeli trawl fishery, Eastern Mediterranean Sea
The trawl fishery of the Mediterranean coast of Israel was analyzed vis á vis catch and fishing effort for the years 1949-2010. The Maximum Sustainable Yield (MSY) was calculated using the Fox surplus-yield model and was found to be 1,413 ton per annum using 1,415 units of effort (fishing days X engine power divided by 1000). Only during nine years (1997-2005) did fishing effort exceed the valu...
