Lethal Temperatures

1. When roach were acclimatized to 20°C. and then subjected to five constant rates of temperature rise, the range of death temperatures depended on the interaction between the opportunity for acclimatization and the exposure to lethal temperatures. 2. At 1/20°C. an hour rise in temperature, roach acclimatized fully, died over the longest temperature range (30.3-35.8°C.) had the highest mean death temperature (32.9°C.) and died over a disproportionate length of time (up to 88 hr.) when compared with other rates. The death temperature range at 1/10° C. an hour was30.8-32.0° C. (mean 31.4°C.) and at 8/10°C. an hour was 31.5 to 32.9°C. (mean 32.9° C.). 3. Roach cannot acclimatize fully at rates faster than 1/20° C. an hour though some acclimatization takes place at a rate of 8/10° C. an hour. 4. Roach excrete more ammonia as the temperature rises but the increase depends on the rate of temperature rise and is delayed for up to 240 hr. at 1/20°C. an hour. 5. The behaviour showed characteristic changes. 6. Roach died from the posterior end forwards; the heart was beating and the gall bladder abnormal when the body was opened.

The Mean

1. The temperature at which 50% of a sample of roach (Rutilus rutilus) die within a week cannot be raised above 33.5° C. by raising the acclimatization temperature. 2. The roach is about as eurythermal as the yellow perch (Perca flavescens). 3. The mean asphyxial concentration of oxygen at 30 and 32°C is approximately 0.8 mg./l. 4. Median survival time at any lethal temperature increases with increase in acclimatization temperature; survival time for any acclimatization temperature decreases as test temperature increases; the temperature at which 50% of a sample die within a week rises by about 1° C. for each 3° C. rise in acclimatization temperature. 5. The behaviour, on transfer to higher temperatures, depends on the acclimatization temperature and the size of the jump in temperature and can be divided into five characteristic stages. 6. Dying fish develop a black pattern; myotomic swimming muscles die first and opercular muscles last. The heart was still beating when the fish were opened but the gall bladder was abnormal.
