中文摘要:
      长毛对虾(Penaeus penicillatus Alcock)是南海重要的经济虾类之一。为了更好地掌握其人工繁殖技木,作者进行了16组不同温、盐度与卵孵化及无节幼体发育关系的实验。结果表明:在供实验的四组水温中,以28±0.5℃为最好,幼体健壮,成活率高;其次为32±0.5℃,再次为24±0.5℃;35.5±0.5℃对孵化发育有害。海水盐度以28.59‰为最佳,其次为35.45‰,再次为23.15‰。20.81‰卵不能孵化;40.38‰对卵和无节幼体发育不利。在相同的温、盐度条件下,卵及无节幼体发育早的体质较好,发育迟的体质较差。温、盐度与长毛对虾卵的孵化及无节幼体发育的关系基本与墨吉对虾的相同。
英文摘要:
      Temperature and salinity show a marked influence upon the incubation perindand nauplius development. If the temperature is higher, the larval development willbe faster and the time needed is shorter. When the eggs and nauplius are placed under the same salinity conditions, andsuitable temperature, the larvae are strong, and the survival rate is high. The mostsuitable temperature for hatching and nauplius stage is 28°±0. 5℃, but water tempera-ture of 35. 5°±0. 5℃ is harmful to the hatching and larval development. If the water salinity is 28. 59‰ to 35. 43‰, the hatching rate is high and the lar-vae are robust. In 20.81‰ salinity, eggs can not be hatched out. In 40.38‰ salinityand temperature at 24°± 0. 5℃ to 28 ±0. 5℃, although incabation is possible but larvaehatched are so weak that they are unable to swim. At the temperature 35. 5°±0 .5℃and the salinity 40. 38‰, the eggs can not be hatched. The nauplius can develop into zoea when the water salinity in 23. 15‰, 28. 59‰or 35. 45‰. In salinity 40. 38‰, the nauplius can develop into zoea, but they are una-ble to swim and the suvival rate is low. In suitable salinity and temperature hatching is comparatively fast, the survival rate is higher.
