• We performed a questionnaire investigation at the Lake Chuzenji to collect information of leisure angling which is one of the background elements for stock assessment, and which cannot be collected through co-operative association, in 1997 and 1998. Answers were given by total of 208 leisure anglers in 2 years. Although there were more boat fishing anglers among the answers, there were more of those who do shore fishing when checked with the sales of fishing ticket in the co-operative. More than half of boat fishing anglers targeted kokanees, <I>Oncorhynchus nerka</I>, and they catch them actually. In the case of shore fishing, the target species varied so that they enjoy fighting spirit with fishes. But the majority fish caught were rainbow trout, <I>O. mykiss</I>. It is interesting that the average age of the anglers shore fishing was approximately 10 years younger than that of boat fishing ones. It is thought that this reflects the diversification of fishing types such as bait, lure or fly fishing whose popularity has been rising among the young anglers recently. In April at the time of removal of the ban on both boat and shore fishing, quite a good number of fishes can be caught in both ways. But in August when the prohibited season closed most of anglers were even not able to catch a single fish.<BR>From the results of this investigation, we can propose some policies for continual development of leisure fishing business of the co-operative association.
