The chromosome of the Chinese Shrimp, Penaeus ofientalis Kishinouye, was studied in preparetions of testis, antennal gland, egg, nauplius, mid-gut, hepatopancreas, beart and bran-chia, obtained by air-dry methods. The procedure of preparetion was as follows: 1. The shrimp were injected intramuscularly with colchicine solution at dosage of 1.5 μg per 1 g body weight; 2. 4-6 hours later the specimens were scarificed, the needed tissues were removed and cut into about 3 mm pices; 3. The tissue were placed in the...

The chromosome of the Chinese Shrimp, Penaeus ofientalis Kishinouye, was studied in preparetions of testis, antennal gland, egg, nauplius, mid-gut, hepatopancreas, beart and bran-chia, obtained by air-dry methods. The procedure of preparetion was as follows: 1. The shrimp were injected intramuscularly with colchicine solution at dosage of 1.5 μg per 1 g body weight; 2. 4-6 hours later the specimens were scarificed, the needed tissues were removed and cut into about 3 mm pices; 3. The tissue were placed in the 0.7% KC1 solution for 10-30 minute hypotonic processing 4. Then fixations were made in at least two changes of Carnoy's fluid for 15 minutes each time; 5. Some pieses were picked onto cleared glass slide, adding a Carnoy's fluid drop, then dried quickly by flaming; 6. Stained with 2% Giemsa (pH= 6.8) for 15-20 minutes.Excepting heart, the other tissues were found to be probably materials for chromosome studies, however the testis and antennal gland are much better. The chromosome numbers for P. orientalis are 2n = 88, n = 44. Because the chromosome of Chinese Shrimp are numerous and very small in size, the karyotypical study was difficulty. A preliminary grouping was tried. The chromosome numbers of some studied Penaeus shrimp and their systematic relationships were discussed as well.

本文对中国对虾(Penaeus orientalis)的染色体进行了研究,材料采用精巢、触角腺、卵、无节幼体、中肠、肝胰脏、心脏和鳃,以气干法制片,吉姆萨染色后进行显微镜检查和摄影。结果表明,除心脏外的其他组织均曾观察到染色体中期相,而以精巢和触角腺为佳。中国对虾的染色体数是n=44,2n=88。由于染色体数目多且小,核型分析比较困难,本文进行了试分析。文章还与对虾属其他已作过染色体研究的种进行了比较,并对它们之间分类学上的关系开展了讨论。本文对对虾遗传育种和进化分类研究具有一定意义。

Histological method has been used to observe the antennal gland of crayfish Marron (Cherax tenuimanus). There are three regions in the antennal gland: coelomosac, labyrinth and nephridial canal. Cells in coelomosac region are elongated and enlarged apically, and flocculant cytoplasmic extrustions were found projecting into the lumen on the apical margin of the cells; the nuclei were located basally, centrally or apically. In labyrinth region all cells are low columnar with basally or eccentrically located nuclei....

Cells in coelomosac region are elongated and enlarged apically, and flocculant cytoplasmic extrustions were found projecting into the lumen on the apical margin of the cells; the nuclei were located basally, centrally or apically. In labyrinth region all cells are low columnar with basally or eccentrically located nuclei. All cells in nephridial region are very flat and can't be divided into sub-regions. The blood space is larger than that ofcoelomosac and labyrinth regions, with many hemocytes compressed in aggregate or linear fashion.

本文首次报道了以组织学手段对澳大利亚淡水螯虾-麦龙虾的触角腺进行研究的结果。根据组织学(?)征麦龙虾的触角腺可分为三个部分,它们依次为:端囊,迷路和肾管。端囊部分的细胞呈柱状,细胞核位于基部或中部。迷路部分的细胞呈短柱状,顶端有刷状缘,核位于基部或亚中部。肾管部分的细胞扁平,核很大偏向顶端,占据了细胞的大部分空间。在迷路和肾管部分没有明显的亚区的分别。

Tetraploids of Penaeus chinensis were induced by temperature shocking and chemical treatment with cytochlasin B(CB). To get batches of fertilized eggs at suitable time, a combination method of manipulation of light cycle and selection of the animal with pre-spawnig behavior was used. In contrast to the natural spawning time, which is mainly at night, the induced spawning occured in the day time. Among the 37 gravid individuals controled under artificial light, 24 shrimps laid eggs between 10:00-16:00. The chemical...

Tetraploids of Penaeus chinensis were induced by temperature shocking and chemical treatment with cytochlasin B(CB). To get batches of fertilized eggs at suitable time, a combination method of manipulation of light cycle and selection of the animal with pre-spawnig behavior was used. In contrast to the natural spawning time, which is mainly at night, the induced spawning occured in the day time. Among the 37 gravid individuals controled under artificial light, 24 shrimps laid eggs between 10:00-16:00. The chemical or temperature treatment were used just before the first cleavage of the fertilized eggs. Altogether 25 batches of eggs were induced in this way. Among them more than two thousand individuals from 5 groups survived to the sub-adult stage with size between 7-10 cm.To detect ploidy level of the different chromosomal set manipulations, a new technique for obtaining metaphase chromosome spreads has been developed. The midgut tissues were proved to be suitable for this purpose. The results of chromosomal analysis showed that the most effective treatment with temperature produced 60% tetraploid, whereas the most effective CB treatment produced 66.7% tetraploid. Some chromosomal mosaic individuals were observed as well. The preliminary comparison study ,of the grpwth rate showed that the tetraploid had statistically significant dominancy of growth rate by about 22% (p=0.01) than the diploid.

利用光控和行为学原理,控制中国对虾在适当时候产卵,在一定的时刻以温度休克和细胞松弛素的方法诱导受精卵发育成为四倍体。作者发展了对虾染色体制备技术,以中肠和触角腺、精巢为材料,从后期幼体直到8~9cm左右次成虾均获得较好的分裂中相。染色体倍性检测结果表明,最好的四倍体诱导成功率达66.7%。共获得10cm左右的实验对虾几千尾。初步观察表明,四倍体中国对虾具有一定的生长优势。
