摘要

This研究了保加利亚黑海沿岸内塞巴尔garfish Belone Belone的遗传及部分形态计量学和分生统计学特征。测定了12个形态计量性状,每个个体计算出6个分生性状。根据两性形态学和分分体分析,没有观察到统计学上显著的性别差异。此外,还进行了DNA条形码分析。对线粒体DNA细胞色素氧化酶亚基I (COI)基因片段进行测序,为物种鉴定和种群多样性研究提供依据。39个序列中发现2个单倍型,单倍型多样性较低(0.146±0.072)。核苷酸多样性也较低(0.00023±0.00011)。由于mtDNA遗传多样性的高度降低,需要采取保护措施。

Morphological and genetic characteristics of garfish Belone belone (L., 1760) (Belonidae, Teleostei) population from the southern Bulgarian Black Sea coast
 This study was conducted to investigate genetic and some morphometric and meristic characteristics of garfish Belone belone from Nesebar in the Bulgarian Black Sea coast. Twelve morphometric characters were measured, and six meristic characters were counted for each individual. Based on both sexes’ morphological and meristic analyses, no statistically significant sexual differences were observed. Additionally, DNA barcoding was done. The fragment of the cytochrome oxidase subunit I (COI) gene of mitochondrial DNA was sequenced to supplement the species identification and population diversity study. Two haplotypes were found out of 39 sequences, indicating a low level of haplotype diversity (0.146±0.072). Nucleotide diversity was also found to be low (0.00023±0.00011). The Nesebar population of B. belone requires conservation efforts, due to the highly decreased mtDNA genetic diversity.
