| Summary, etc. | The Southern King Crab (SKC), Lithodes santolla, has supported a growing fishery in San Jorge Gulf<br/>(Patagonia, Argentina) since 2011. This fishery is developed by vessels called crabbers. SKC is also caught<br/>as bycatch in the Patagonian shrimp fishery, a major crustacean fishery in the Southwestern Atlantic<br/>Ocean. In this work, we characterized SKC bycatch in shrimp fishery and compared 1994e1996 data<br/>(which reflected little fishing impact) and 2011e2012 data (at the beginning of the current SKC fishery by<br/>crabbers in San Jorge Gulf), to determine the particular effects of bycatch on the SKC population. The<br/>frequency of occurrence of SKC in shrimp hauls was 84.08%. However, the relative abundance was low, in<br/>most of the hauls SCK represented less than 5% of the capture. Between 2006 and 2011, the estimated SKC<br/>bycatch was 2432 tn/year. Frequency of occurrence and abundance were higher in the same area where<br/>crabbers operate. SKC bycatch is commonly discarded, but, in 18% of the hauls, SKC are processed on<br/>board, although this is illegal. Mortality estimated at the beginning of handling was 19%, but this value<br/>may be greater due to the long time of onboard handling. SKC bycatch include critic stages of its life cycle<br/>such as juveniles, ovigerous females and molting individuals. Juveniles represented 26.9% of the total SKC<br/>bycatch, while ovigerous females represented 28.1%. Sex ratios and male size showed no differences<br/>between 1994e1996 and 2011e2012, whereas the proportion of ovigerous females decreased between<br/>both periods. This decrease can be related to the interference of trawlings in their reproductive migration<br/>to coastal waters or in their mating grounds. We consider that the main problem of SKC bycatch is the<br/>detrimental effects on its reproductive potential due to the increase in the proportion of non-ovigerous<br/>females and the mortality of ovigerous females along with extensive handling, which can also result in a<br/>significant egg loss. |
