• '. <br />17 <br />than we would have expected in our earlier thinking. We had assumed <br />that the outward migration would have been fairly complete. <br />This Upper Lily Park site vrould seem to be a -significant place <br />for this and future studies. An effort was made to map it in as <br />much detail as possible. This map is included with this report <br />(Figure 2). Hopefully, it will illustrate some of the characteristics <br />of good squawfish habitat. 4~Jhich of these characteristics are of most <br />importance, can only be summarized at this time. It will be noted that <br />there is a riffle at the upper end. Oon Toney (1974) reports that the <br />squawfish at the Willow Beach Hatchery spawned at the head of the race- <br />way where the water was percolating through the gravel. The eggs <br />appeared to be adhesive, some in clumps while others adhered to the <br />gravel. One might expect the squawfish therefore to spawn in riffles. <br />Be]ow the riffle are pools and cut-off areas which could provide forage <br />for the young. At net #5 (Figure 2) we caught most of our ripe males. <br />At net #Z we caught our ?_ largest fish vrhich were suspected to be spent <br />females. Net #5 eras also productive. It was from this location that <br />-ve caught the 2 squawfish on August 30. We caught only 1 squawfish <br />in net rr3 and none in either 1 or 4. bJe might tentatively hypothesize <br />that deep pools and back eddies are likely places to look for them. <br />Possibly the females prefer the pools while the males prefer the <br />back eddies. There is sorne similarity between the eddy at net #6 <br />and the one at the P~lantle Ranch site in Castle Park, also mapped in <br />this report (Figure 3). Both were hangouts for ripe males. <br />To date we cannot say what influences the summer migration. It <br />has been assumed that it was for the purpose of spawning. That may <br />
