The meat of Chinese horseshoe crab (Tachypieus tridentatns Leach, 1819) is edible. How to use it in this connection has drawn much attention, especially since the horseshoe crab-reagent was successfully extracted from horseshoe crab's blood. This kind of reagent is being used on medical examination to diagnose many diseases, and also in the aspects of canned food inspection and electron bionics.

The meat of Chinese horseshoe crab (Tachypieus tridentatns Leach, 1819) is edible. How to use it in this connection has drawn much attention, especially since the horseshoe crab-reagent was successfully extracted from horseshoe crab's blood. This kind of reagent is being used on medical examination to diagnose many diseases, and also in the aspects of canned food inspection and electron bionics. It has, therefore, the practical value and is of significance in research work of artificial breeding so as to develop aquatics and supply larvas for medical purpose.a) We put the adult couple (male & female) of well selected kinhorseshoe crab into a spawning pond with a sheet of sand 20-30cm thick and a flowing flash for achieve good results of excreting ovulation and sperm.b) The zygotes were incubated 36-43 days in sea sand and 42-54 days in water with water temperature 26℃-31℃, specific gravity 1.012-1.020, pH value 7.5-8.3, making more than ninety-five per cent at the incubation rate, and the larvas number to 28265 in all.c) The larvae were nursed in a container in three different conditions: delicate sand bed, coarse sand bed, and no sand bottom, changing water and throwing baits once a day. The best concentrated baits were Platymonas dicrateria zhaniiangensis Hu,Chaetoceros muel-leri Zommermann and a little diation plus some organic substance etc. The larvae shed first fime within 43-50 days in delicate sand bed, within 72-86.8 days in coarse sand bed, under the conditions of 25℃-30.5℃, specific gravity 1.014-1.020, pH value 7.5-8.3 Oxygen-solute 3.5mg/L on more. But in no sand bottom the larvae shed nothing even for 115 days in same conditions. However, the survival rates after 115 days in all the above mentioned conditions came up to ninety five per cent and more.

中国鲎肉供食用,特别是用鲎血提取鲎试剂获得成功后,它的利用价值已引起人们的重视。关于鲎的生物学研究,前人已有报道,但对中国鲎人工育苗试验研究,在我国尚未见有报道,作者于1981—1982年在室内水池中,对亲鲎的产卵、受精、孵化、幼体培育和饵料等进行了研究,并于1981年孵出幼鲎28265个,培育115天,成活率达95%以上,初步获得育苗成功。这一研究成果,为人工增殖药用动物,提供了苗种。

Water temperature shows a marked influence upon the incubation period of the eggs of the two species. Within the range of 20—35℃, the higher the temperature, the shorter is the incubation period. The curves of egg incubation rate of both species related to temperature are logistic. They can be expressed respectively by the following formulas:N_1+=1+e~(4.9347-0.1872t)/0.1095 and N_h=1+e~(5.2077-0.2117t)/0.1104 Where, N_n, N_h—rate of D. niedashui and D. hupehensis respectively; t—temperature.When...

Water temperature shows a marked influence upon the incubation period of the eggs of the two species. Within the range of 20—35℃, the higher the temperature, the shorter is the incubation period. The curves of egg incubation rate of both species related to temperature are logistic. They can be expressed respectively by the following formulas:N_1+=1+e~(4.9347-0.1872t)/0.1095 and N_h=1+e~(5.2077-0.2117t)/0.1104 Where, N_n, N_h—rate of D. niedashui and D. hupehensis respectively; t—temperature.When the water temperature increases, the instantaneous hatching rate of both species increases according to the following equations: Y_n=0.0205t—0.3119 and Y_h=0.030t—0.5171.Where, Y_n, Y_h—instantaneous rate of each species; t—temperature.The miracidia of these allied species show a strong positive phototaxis and prefer swimming near the surface of water. The two cercariae shed from the gastropods 18—25 days after infection. They appear to be phototatic and suspending near the surface of water. The cercariae emerge from the snails discontinuously and in spurts at intervals. The emergence peak of the cercariae of both species appears from 8 to 10 am every day. Their emergence begin to reduce囔 by 2 pm and completely cease, after 6 pm.The populations of the two cercarie may also increase in logistic curves. They can be expressed respectively by the integral form of the logistic equations:N_n=209 362.8315/1+e~(4.3368-0.1308t) and N_h=448 376.6514/1+e~(5.8165-0.1495_t)Where, N_n, N_h—population of each species; t—day.

本文比较研究了倪氏复口吸虫(Diplostomum niedashui Pan & Wang)和湖北复口吸虫(Diplostomum hupehensis Pan & Wang)早期生活史的实验生态,包括温度、光照度对它们直接和间接的影响及某些数量的变化。

After temperature-variated treatments for the dormant period of Coccinella septempunctata, the insect laid eggs after feeding for 7—10 days. The numbe of eggs laid by each individual was 790—1300, and the incubation rate was more than 85%, shortening feeding period for 60—90 days. Using this species of ladybirds to control aphids is a simple, low-economic and feasible method which saves much of labour and feeds.

应用人工控制七星瓢虫眠期变温处理后,投食7—10天即可产卵,产卵量790—1300粒,卵的孵化率为85%以上,可缩短饲养期60—90天。应用于瓢虫治蚜是一种省工省料、经济成本低、简便易行的方法。
