湛江沿海五种石斑鱼线粒体DNA的RFLP分析

In this paper, genetic diversity of intraspecies, and genetic relationship of interspecies in Epinephelus spp. (E. merra, E. fario, E. awoara, E. akaara and E. septemfasciatus) were assessed by using mitochondrial DNA restriction fragment length polymorphisms (mtDNA RFLPs).The samples were collected from the coastal area of Zhanjiang,Guangdong province. MtDNA was extracted from the fresh liver tissue by applying a difference centrifugation procedures. Using 17 restriction enzymes with 5-or 6-bp recognition sites, the purified mtDNA was cleaved by single enzymes. These enzymes included BamH Ⅰ，Bgl Ⅰ，Bgl Ⅱ，Dra Ⅰ，EcoR Ⅰ，EcoR Ⅴ，Hind Ⅲ，Kpn Ⅰ，Mlu Ⅰ，Pst Ⅰ，Pvu Ⅱ，Sal Ⅰ，Sca Ⅰ，Sma Ⅰ，Sty Ⅰ，Xba Ⅰ and Xho Ⅰ. The phylogenetic analysis was done using the Neighbor joining(NJ) method and Unweighted pairgroup method with arithmetic mean(UPGMA) method. Genetic diversity indices such as haplotype diversity (h), average genetic distance between haplotypes (P) and nucleotide diversity (π) were calculated using Nei and Li's segment method to quantify the genetic diversity within species. There were 8, 5, 8, 5 and 2 haplotypes detected within E. merra, E. fario, E.awoara, E.akaara and E. septemfasciatus, respectively. The haplotype diversity (h) was 0.8943, 0.6186, 0.9242, 0.6927 and 0.1820,respectively. The average genetic distance between haplotypes (P) was 0.62%±0.31%, 0.64%±0.37%, 1.12%±0.55%,0.72%±0.42% and 0.45%, respectively. And the nucleotide diversity (π) was 0.22%, 0.13%, 0.46%, 0.17% and 0.04%, respectively. The wild groupers in the Zhanjiang Coastal Area exhibited a relative higher level of genetic diversity. The net genetic distance between species (P_net) was 0.0694（E. merra - E. fario）,0.1337（E. merra - E. awoara）,0.1090 E. merra -E. akaara）, 0.1286（E. merra - E. septemfasciatus）,0.1590（E. fario -E. awoara）,0.0825（E. fario -E. akaara）,0.1153（E. fario - E. septemfasciatus）,0.1131 E. awoara - E. akaara）,0.0724（E. awoara -E. septemfasciatus） and 0.1336（E. akaara - E. septemfasciatus）. Both NJ and UPGMA methods yielded an identical phylogenetic tree for the five species. The E. merra and E. fario first clustered together, then joined with E. akaara, and finally clustered with E. awoara and E. septemfasciatus.

海湾扇贝个体间单向人工授精的分子生物学验证

Hybrid family of Argopecten irradians irradians was created by fertilization between two northern bay scallop individuals. Two families were analyzed in this study. The first family, P_a-P_b, is a pair mating between two scallops named P_a and P_b, while the second one crossed by individuals of Y₁ and P₀. Marker inheritance and segregation were studied in the 10 progenies of each family by randomly amplified polymorphic DNA (RAPD) analysis. 102 RAPD primers were first screened by parental animals of both families. Only the primers with polymorphisms between the two parental animals in each family were select ed for further analysis. In both families, parents and 10 progeny were nalyzed with selected primers. In family P_a-P_b, a total of 122 bands generated from 12 selected primers. 37 of them were polymorphic between two parents. The maternal P_a of this family had 17 molecular markers while paternal Pb had 20 markers. In Y₁-P₀，95 bands were produced by 10 selected primers. 32 bands were polymorphic between maternal Y₁ and paternal P₀, who had 17 and 15 molecular markers respectively. In both families, each progeny analyzed in this study had at least 8 maternal markers and 5 paternal markers. Based on segregation patterns at all markers analyzed, we concluded that none of the progeny analyzed were from self-fertilization, and oneway hybridization between two individuals was successful in both of the two bay scallop families.

线纹尖塘鳢的形态生物学与核型

This paper reports the morphological character and karyotype of Oxyeleotris lineolatus. Oxyeleotris lineolatus is native in Australia and call ed sleepy cod. It belongs to Oxyeleotris, Eleotridae, Gobioidei, Perciformes in taxonomy. Recently, it was introduced to China and local people were not familiar with it. So we carried out this study. 30 individuals have been observed and some data were recorded. It has a large mouth that is in front and up. The mandible stands out and is longer than the up jaw. There are many rows of thin teeth in up and down jaws. The pelvie fins are located in chest and pectoral fins are large and fanlike. There are two dorsal fins. The tail fin is circular. Gill rakers are sparse and the number of gill rakers is 8-12+3-4. The gas bladder belongs to physoclistaus and its stomach is strong and I-like. The intestine is thick and short and no pyloric caecas. The length of the digestive path is 48.1％-80.3% of the length of body. Its liver has two lobes and the liver weight is 4.1%-7.2% of the body weight. The digestive organs characters are same as the trait of flesheater fish. Its scale belongs to ctenoid scale and its body surface shows several long lines. There is not lateral line in the body. The number of vertebra is 26-27 and it has 10-11 pairs rib. The number of diploid chromosome is 2n=46 and the karyotype formula is 2sm+8st+36t，NF=48. The relative length of chromosome is from 1.37% to 3.48% and it is continuity. No strange size chromosomes relation to sex was observed. The karyotype of Oxyeleotris lineolatus is similar to that of Oxyeletris marmoratus Bleeker from South East Asia and both of them belong to Oxyeleotri. It testifies the correctness of traditional classification on cytology.

桑沟湾水域叶绿素a在海带收获前后的变化及其影响因素

依据2014年5月和8月2个航次走航和定点连续调查资料,分析了桑沟湾水域叶绿素a的空间分布及海带养殖区叶绿素a(Chl.a)的昼夜变化特征,同时结合所调查的温度、盐度 、pH和营养盐等分布特征,分析了桑沟湾水域Chl.a浓度与理化因子的关系,探讨了海带收获前后Chl.a的变化及其影响因素。(1)走航调查的结果显示,桑沟湾夏季Chl.a浓度显著高于春季。桑沟湾春季表、底层总Chl.a浓度均值分别为(0.67±0.39)和(0.50±0.31)μg/L,表层Chl.a浓度高于底层,春季表层整体表现出自湾内向湾外逐渐降低的趋势;夏季表、底层总Chl.a浓度均值分别为(3.39±1.53)和(3.12±1.43)μg/L,表层Chl.a浓度高于底层。桑沟湾夏季表层Chl.a高值区出现在海带养殖区,低值区出现在贝类养殖区,夏季底层Chl.a高值区出现在贝类和海带养殖区,低值区出现在外海区。(2)定点连续监测结果显示,春季海带养殖区Chl.a浓度变化范围在0.24~0.95 μg/L,均值为(0.70±0.19)μg/L,昼夜波动较小。而夏季海带养殖区Chl.a浓度变化范围在2.01~4.66 μg/L,均值为(3.04±0.82)μg/L,昼夜波动较大。桑沟湾海带养殖区夏季Chl.a浓度显著高于春季。春季海带养殖区营养盐平均浓度及硅磷比、氮磷、硅氮比均显著低于夏季。(3)桑沟湾春季表层Chl.a浓度主要与温度、硅酸盐呈显著正相关,而夏季底层Chl.a浓度与盐度呈显著正相关。桑沟湾海带收获前后Chl.a的变化及分布受温度、硅酸盐、盐度、养殖环境状况和水文环境的共同影响,多元的贝藻养殖模式是影响Chl.a变化及分布的重要因素。
