3 Since thecoregonine fish populations of western Canadian lakes are generallyparasitizedbythetapeworm,triaenophorus~andtheflesh of some individual fish is rendered aesthetically unfit for the market, anintensiveresearch program has progressed for some years in an effort to eliminate the parasite, or at least to lessen the degree of infection. Sufficient knowledge has been gained of the life cycle of the parasite to attempt a means of control, among other, by elimination or reduction of the cisco population. The ciscoes, Leucichthys spp. play a vital part in the propagation of the tapeworm. Present commercial fishing gear used in western Canada does not readily lend itself as an efficient means of intensive exploitation of the cisco population to the exclusion of other species. The gill-nets commonly in use have the further disadvantages of being expensive to buy and expensive intimoandlabourtooperate. The desirable gear must catch large numbers of ciscoos and must not kill tho other species as the gill-not does. Since tho nature of tho problem suggested livo-trapping the suitability of a Lake Erie typo trap-not was investigated. Ingenoral,atrap-netisalargeundorwaterenclosurowithanentrance fitted with a series of bafflos making it difficult for a fish to escapo onco it is in the box-like enclosure. Along fence-like structure loads to tho entrance which serves to guide a fish to the interior as it attempts to swim around tho obstruction. The trap-net is made of strong cotton mesh seamed on to heevy ropes for strength and flexibility. Lacking a rigid frame, it is held in shape by iron weights at cloee intervals seamed on to its bottom margins, and by metal buoys along the top margins, similar in size,md shapo t.o 48-ounce juice cans, The ",hole structure ie moored

5 below tho surface by lines leading out to soveral anchors. The sizes of trap-nets vary with certain conditions. A diagram follows.,shoming the principal dimensions of the Lake Erie type net used in theoxperiment. Tho length of tho loador, only a section of which is shown in the diagram is 220 yards. The, leader of the trap-net is usually set perpendicular to the shore. Fish moving along parallel to the shore encounter the leader end apparently attempt to circumvent the obstruction rather than swim through the meshes which they could easily do. It is believed that many attempt to pass the leader on the "deep" end, Le. the end farthest from the shore, and are thus led into the funnel- The two wing-like structures shown in the centre of the diagram are referred to as "peaks" or "hearts". The shape of the peaks aids in inducing the fish to continue on into the tapered section, called the "big tunnel". This section, closed on all sides, is equipped as shown in the diagram with 2 baffles called The big tunnel leads into a box-like sectionequippedwithafunnelshaped opening. This box is referred to as tha "second crib". A similar box, the "firstcrib",orliftingcrib,servesasthefinalencloeureinthe trap-net. This unit is raised to the surface and a section is unlaced in order to clear the net of Different mesh sizes are used in tho construction of tho various units. The mosh sizes used in the experimental net wore as followsl Leader-a-inch Hearts - S-inch Bigtunnel-S-inch Socondcrib-3-inch First crib 2-inch (bottom half) 3-inch(tophalf)
6 The complete net is carefully overhauled onto thereardeckofaboat of at least 20 feet in length, beginning with the first crib, and ending with the leader, so that the leader will be on top. An anchor is fitted to the bridle on the end of the leader, and an anchor is fitted to a long line attached to the bridle of the lifting crib prior to setting. At the selected place, the leader anchor is thrown over the stern of the boat, and the net pays out as the boat moves slowly ahead, until the crib anchor is finally dropped. These two anchors serve to keep the net from drifting until the remaining anchors can be atteched. These are usually set from a skiff in which the anchor lines and anchors have been arranged, the larger boat meanwhile holding the net up so that its shape can be observed. Three anchors are placed on each side of the trap-net in addition to the two at eitherend. all anchors are set the net is allowed to drop to the bottom. To clear the net of fish, it is necessary to raise the lifting crib To accomplish the raising a line is attached to the crib anchor line and is carried to the surface by a buoy. This arrangement allows the crib to be raised and "draped" across the stern of the vessel, whose fore and aft axis i satrightangles to that of the trap-net. lsectionofthecribisunlacedallowingaccesstothe fish which are scooped out using a long handled dip-net. Since practically no fish have been injured, they may be returned to the water if desired. Several species occurred in the catches, and are listed below together

This is in the general area of the fishery grounds. The net was fished until July 31, and was lifted 7 times. It was estimated to have averaged 280 pounds of fish per lift, mainlyburbot. Duringthis year there was a general decrease in the catch of burbotwith each successive lift. In 1951, the trap-net was set about 4 miles offshore in the same general area,nearfrogreefinadepthof30feet. It was set early in June and was fished for 22 days. Thersvlere 14 lifts which averaged about 190 pounds each. Thecatch was again mainly burbot, but the numbers taken each time remained fairly steady. The trap-net was not fished again until July3,,1953. It was set in nearly the same place as in The net was lifted 6 times during the 20 days it was fished. The lifts were estimated to average 84 pounds, but the catch of burbot wasmarkedlylowerthaninotheryears,andremainedfairlyconstant with each lift. For about 2 weeks during August, and from September 9 to October 26, 1953 the trap-net was set near Elk Island in the south end of the lake. nuringaugust it caught very few fish, but improved during the latter period when large numbers of burbot were taken. The catches fell off toward the end, but the fall storms had pulled the net somewhet out of shape, and it was probably not fishing at full efficiency. Nevertheless,theestimatedcatchesaveragedabout2BOpounds. The numb~- ~f indivioljals +~kel1 "uring each year is shown in Table I and

As shown in Table II only 2 per cent by weight of the total catchas ware ciscoes, 4 per cent freshwater drum, 5 per cent suckers, while burbot amounted to 82 per cent. Commercial species combined amounted to 7 per cent of the total R latively, fair numbers of ciscoes were taken during 1951 and in 1953 at Big Black River, but the catches fell far short of takbg ciscoas in sufficient quantities to materially reduce the population. The trap-net failed to takeciscoes in quantity probably because they are widely dispersed during the period of open water.

This may be due, in part at least, to years of an exclusive gill-net fishery where mesh sizes have been manipulated to select mainly commercial fish, end where fishing effort has been diverted eway There were indications that a trap-net of different dimensions could be designed for inshore areas to take sauger, yellow walleye andyellowperchin quantity. fishery.

During the same period in 1951, 122 yellow walleye, 105 sauger, and 16 yellow perch were tagged. The tags were small white numbered plastic discs fastened at the anterior margin of the dorsal fin by means ofa pin through the dorsal flesh. Ofthe139walleyetagged,22werereturned,ornearly16percent. Sauger tagged amounted to 127. Nearly 14 per cent or 18 fish were returned. Of 16 taggedperch,2wererecaptured,orl<!tpercent. These data include the small number of fish tagged in 1950, of which 2 walleye were recaptured. No reward was offered for recovery of any tag. A large proportion of the returned fish were at liberty a short time only. Three fish were recaptured in the trap-net, and several more were taken in commercial fishermen's gill-nets which were set in the same ~icinity. More than one-half of thereturns,or24fishofallthreespecies,wereretakenwithinlmonth of tagging. Thirty-one fish (or 7 additional ones) were retaken within 4 months,and9wereat liberty longer than 4 months. Table III shows the time at liberty of the 41 specimens which were recaptured.

13 There was no apparent difference in the tendency to disperse between yellowwalleyeandsauger. Both of the two recaptured yellow perch however, were neer the tagging site, one, three days after being tagged, and the other more than a year later. Sauger and yellow walleye showed a marked tendency to disperse, and did so in several different directions I Table IV gives some idea of the distance that individuals moved. The accompanying map plots the approximate positions at which the fish were recaptured. Table IV.

In addition, fishing effort was many times greater south of the tagging site with consequent better chances of recovery. Nevertheless, a sauger was rec'aptured more than 50 miles north of the tagging site more thana year later.
