Abstract
A survey was conducted at Chettuva, Thrissur
District, Kerala to observe the mud bank fishery in
July 2016. Very low fish catch was recorded at
Chettuva Fisheries harbour prior to the formation
of mud bank. A sudden increase in catch after onset
of mud bank formation prompted many fishers from
nearby fishing villages such as Kalamukku
(Ernakulam district); Chettuva, Azhikode and
Thalikulam (Thrissur district) and Ponnani
(Malappuram district) to temporarily migrate to
these fishing grounds during the period
reported.Ring seiners, motorised mini trawlers and
non-motorised crafts were operated. Motorised
wooden mini trawlers with either double or single
outboard motor, with each boat having 9.9 hp power
were also employed for fishing. Since mini trawl
was operated with two attached crafts, it was
locally known as double net
