Mud Crab (kekra)

Introduction

Since Mud crabs (Kekra) are highly demanded in the international market, 90 percent of local Mud crab catch is exported from Pakistan, but there is still some of it left for local consumption.

There are two variants of mud crab generally found in Pakistan. The first and most common variant is the export rejected (rejected when either of the claw is broken). These mud crabs are very economical. The second variant is the large size, export standards Mud crab which is approx. 400 to 700 grams in size and is without any broken leg or claw. However, this second variant is costly because of international demand.
