| Abstract | Investigations were carried out to study comparative escapement of different sizes of fish and prawns from diamond and square mesh codends of 20 mm mesh size. Both the codends were covered with small meshed (10 mm) webbing to collect the fish which escaped through the codends. The mean selection length and selection factor for four species of fish (Johnius spp., Leiognathus spp., Dussumerio acuta, Thryssa purava) and two species of prawns (Parapenaeopsis stylifera and Metapenaeous dobsoni) were worked out for both the codends. The mean selection length was greater for square meshes indicating the superiority of this type of mesh over the conventional mesh in releasing more juveniles of the species studied. |
