Anyone has field experience on eficiency of using this type of casting traps (image attached) versus more "traditional" pots ? If applied to the blue crab, would be optimal.
The idea would be to use these casting traps to cover a wider geographical area (also more replicates) on a much shorter time period. And avoid the trouble of going once to deploy the pots and having to go back one or two days later to retrieve them.
Any thoughts or knowledge on any study carryed-out with such casting traps would be well appreciated.
Dear Joao,
In India, especially in the southern part, a special net called crab net is used to harvest to blue swimming crab Portunus pelagicus which is a bottom set gill net. Of course, there are other crabs like P. sanguinolentus and Charybdis feriata that are also caught as bycatch along with some fishes and crustaceans. If you are interested, I can send you some details. All the very best with research.
best regards
Deepak
Thanks for your answer Deepak Samuel Vijay Kumar !! We already have some good results of catching the blue crab with conventional gill nets, but that requires a boat to set and retrieve the net and we were looking for something a bit more easy to move round.
Best regards,

Hi João ,
The crab rings are widely used in brackish waters of India, especially from south-west coast for mud crab. Since this fishery is sustenance level, reports is very limited. Currently, we working on traps and pots of India, a review article on this underway. I'll share you once its published.
Best wishes,

That's nice to know Dr Chinnadurai..Eager to know the status of the same..
Deepak Samuel Vijay Kumar Thank you sir, The paper is in review now...
That must be interesting Shunmugavel Chinnadurai ! But you are comparing the use of such traps for scientific studies or on the fisheries side ?
Thanks
