Endrin becomes less toxic to fish as </p><p>the temperature of the water is lowered. 2. Eggs and larvae of fish are far more </p><p>resistant to Endrin than adults. </p><p>3. When Endrin is applied in a paddy- field, its toxicity to fish may remain for more than a month. The toxicity of the granule form seems. to remain longer an that of dust or emulsion. </p><p>4. When Endrin was spread in i to 3 tan (0. 245 to 0. 735 acre) of paddy-field, the toxicity to fish was recognized in the adjacent stream area, about 100 meters from the treated field. The toxic effects </p><p>may differ according to the conditions of he waterway from the field. </p><p>Acknowledgment </p><p>The authors desire to acknowledge e assistance rendered in this work through a grant from the Velsicol Corporation. </p><p>Literature Cited </p><p>Doudoroff, Peter, et al. 1951.

The develop- ment of a dense growth of plankton and the warming of the water during the summer were favorable to the fish, not the angler. </p><p>In August 1956, the technical field officer made a survey of spawning at the lake's only tributary used for spawning. This investigator concluded that there was adequate spawning and that the population would stand greater exploitation. The local society accepted his conclusions and took the steps necessary to put his recom- </p><p>mendations into effect. Lake Tutira was </p><p>opened for a full year's fishing, and the angler was required to have a license and a permit so that the species, size, and time when the fish were caught could be determined. On the basis of these data, it should be possible to set seasons to give a maximum exploitation of the stock at a period when anglers could readily catch the fish. </p><p>More than 80 fish averaging 3; 5 pounds were caught during the winter season. A survey of spawning at the end of August 1957 showed that winter fishing had had almost no effect on the trout population in Lake Tutira. </p><p>162 OCTOBER 1958 </p><p>Dow</p><p>nloa</p><p>ded </p><p>by [</p><p>Uni</p><p>vers</p><p>ity o</p><p>f W</p><p>ater</p><p>loo]</p><p> at 0</p><p>7:14</p><p> 11 </p><p>Oct</p><p>ober</p><p> 201</p><p>4 </p></li></ul>
