Sharks Sample Clauses

Sharks. Since 2008 there have been ongoing discussions and preparations for a new agreement on a global scale to protect sharks such as the Whale shark (Rhincodon typus) and the Great White Shark (Carcharodon carcharias) under the auspices of CMS. An Action Plan is currently in preparation for mid-2009, which will provide the foundation for the agreement finalisation later this year.

Sharks. There is potential for hook leads to increase shark bycatch. The leads abut the hooks and cover the lower 10 cm of the branch line, which is a section of the branch line that is commonly bitten, and weakened, by sharks. Thus hook leads may reduce the number of bite-offs compared to 60 g at 3.5 m branch lines. In the analysis the data for shark catch were combined to increase the sample size. The species considered were dusky, silky, smooth hammer head, blue, short finned mako and long-finned mako sharks. There was no significant effect of line weighting regime on the catch rates of sharks, nor was there an effect of bait species (Table 7). Mean catch rates were 3.73 ± 0.85 sharks/1200 hooks by hook lead branch lines and 3.44 ± 0.63 sharks/1200 hooks by 60 g at 3.5 m gear, respectively (n = 29 sets and a total of 118 sharks caught on both weighting regimes combined).
