In the shrimp pot fishery, depending on the weather at sea and sea conditions the pots are left on the sea bed from a couple of days to over 10 days. An interesting matter for thought is whether the catch will increase in proportion to an increase in the period of immersion for the shrimp pots. This paper deals with the case of the pink shrimp Pandalus borealis and a compilation of 7 years' data acquired from shrimp pot boats operating in the Japan Sea in analysed here. There seems to be no direct relationship between the catch and period of immersion, although the difference in the catch for the pots set and left for 1 day and the pots set and left for 2 or more days appears to be significant. This phenomenon is closely understood in the case of the larger shrimps that entered the pots in greater numbers when compared to the smaller shrimps. The results from this analysis and the results from the laboratory experiments were compared and further studied.
