Development of non-damaging trapping apparatus for the spanner crab (Ranona ranina) fishery

Both male and female spanner crabs (Ranina ranina) readily moved up inclined ramps made from numerous materials and there were no significant size related behavioral differences. This suggested that Ranina ranina could be trapped in "entrance type" non­-entangling apparatus. A range of top and side...

A comparison of the fishing characteristics and inefficiencies of different otterboard designs under field conditions

Unlike the majority of engineered equipment, the design of fishing gear is tested ultimately in its ability to take or capture live animals which are able to modify their escape responses. For this reason, increases in the efficiency of operation and optimization of hydrodynamic design are not...
