AbstractWe evaluated the effect of high temperature on Apostichopus japonicus gametes. Gametes were exposed to the optimal temperature (18 degrees C; control) or one of six high temperature treatments (26, 27, 28, 29, 30 and 31 degrees C) and the cleavage rate (CR) of fertilized eggs was measured as an indication of fertilization ability. At control temperatures (18 degrees C), the male and female gametes had high fertilization ability (CR >= 95.0%) in 5 h and the time at which 50% of gametes lost the ability to successfully fertilize (LT50) was 7.03 h. All gametes were non-viable after 9 h. When male and female gametes were both exposed to high temperature, the LT50 was lower than that when female or male gametes were treated individually at the same high temperature (P < 0.05). The LT50 was lower for male gametes treated alone than for female gametes treated alone. In conclusion, exposure to high temperature results in a decline in fertilization ability of A. japonicus gametes, and this decline was more rapid at higher temperature. The female gametes were more resistant to high temperatures than male gametes.
