Modifications to reduce bycatch in prawn trawls: A review and framework for development

  • M. Broadhurst

    Reviews in Fish Biology and Fisheries
  • 2004
It is shown that inherent variabilities among differentfisheries greatly influence the types of designs that need to be applied and although some designs have the potential for application across different fisheries, significant modification and re-evaluation are often required.

Estimating Collateral Mortality from Towed Fishing Gear

It is proposed that because the mortalities of discards typically are much greater than escapees, the primary focus of efforts to mitigate unaccounted fishing mortalities should concentrate on the rapid, passive, size and species selection of nontarget organisms from the anterior sections of towed gears during fishing.

Aspects of Reproductive Biology of the Scalloped Hammerhead Shark, Sphyrna Lewini, off Northeastern Brazil

The results support the few existing data on the reproductive cycle of S. lewini in other areas and suggestCopulation and parturition appear to occur outside the sampled area and possibly closer to the coast.

An overview of the shallow-water calcified hydroids from Brazil (Hydrozoa: Cnidaria), including the description of a new species

The few existing studies of Brazilian Millepora spp reveal several remarkable features of this genus, which are an important component of Brazilian reefs, with colonies that can reach up to 2 m in diameter.

Bottlenose Dolphins, Tursiops truncatus, Removing By-catch from Prawn-trawl Codends During Fishing in New South Wales, Australia

During a fishing trip to record video footage of fish escaping from a by-catch reducing device located in a commercial prawn trawl, two bottlenose dolphins, Tursiops truncatus, were observed to…

Reproductive biology of the Caribbean sharpnose shark, Rhizoprionodon porosus, from northern Brazil

Conurrent ovulation and gestation cycles and a clear relationship between embryonic development and maturation of the ovary showed that females are ready to copulate immediately after parturition.

Mitigating unaccounted fishing mortality from gillnets and traps

Gillnets and traps often are considered to have fewer holistic environmental impacts than active fishing gears. However, in addition to the targeted catches, gillnets and traps still cause unwanted…

Review of a small-scale pelagic longline fishery off northeastern Brazil

The annual catches of four small longliners operating off northeast Brazil from 1983 to 1997 were examined across different areas and locations. The total catch comprised tunas (30%), sharks (54%),…
