Compilation of information on blue shark (Prionace glauca), silky shark (Carcharhinus falciformis), oceanic whitetip shark (Carcharhinus longimanus), scalloped hammerhead (Sphyrna lewini) and shortfin mako (Isurus oxyrinchus) in the Indian Ocean
At the Ninth Session of the Indian Ocean Tuna Commission in 2005, the commission adopted the resolution 05/05 , arising from the work of the Compliance Committee, concerning the conservation of sharks caught in association with fisheries managed by IOTC. It is stipulated that Contracting Parties and Cooperating non-Contracting Parties (CPCs) shall annually report their data for shark catches, r...
متن کاملAcanthocheilus rotundatus (Nematoda: Acanthocheilidae) from the intestine of shark (Carcharhinus macloti) in Persian Gulf, Iran
In a parasitic study on five Sharks (Carcharhinus macloti) caught from the Iranian coasts of Persian Gulf, two of five sharks appeared to have nematode in their intestine. Using light microscopy, the nematode was identified as Acanthocheilus rotundatus. A. rotundatus is characterised by 3.3-4.5 cm in length, semithick cuticle, small lips, semicircular and tri-lobed pseudolabia (not offset from...
متن کاملModelling tooth–prey interactions in sharks: the importance of dynamic testing
The shape of shark teeth varies among species, but traditional testing protocols have revealed no predictive relationship between shark tooth morphology and performance. We developed a dynamic testing device to quantify cutting performance of teeth. We mimicked head-shaking behaviour in feeding large sharks by attaching teeth to the blade of a reciprocating power saw fixed in a custom-built fra...
متن کاملPost-release survival of juvenile silky sharks captured in a tropical tuna purse seine fishery
Juvenile silky sharks Carcharhinus falciformis comprise the largest component of the incidental elasmobranch catch taken in tropical tuna purse seine fisheries. During a chartered cruise on board a tuna purse seine vessel conducting typical fishing operations we investigated the post-release survival and rates of interaction with fishing gear of incidentally captured silky sharks using a combin...
متن کاملTrade-offs in the design of fishery closures: management of silky shark bycatch in the eastern Pacific Ocean tuna fishery.
Bycatch--the incidental catch of nontarget species--is a principal concern in marine conservation and fisheries management. In the eastern Pacific Ocean tuna fishery, a large fraction of nonmammal bycatch is captured by purse-seine gear when nets are deployed around floating objects. We examined the spatial distribution of a dominant species in this fishery's bycatch, the apex predator silky sh...
