Cluster analysis by upgma methods indicated that these five stocks might be divided into three clusters . results of rapd a nalysis suggested that extensive genetic diversity was detected in this species and the genetic divergence among stocks was relatively high ; upgma phylogenetic tree showed there existed three geographic populations of p . polyactis in the yellow sea and the east china sea , which supported the previous conclusion by morphological and ecological methods . part two : the genetic diversity between trichiurus lepturus and eupleurogrammus muticus random amplified polymorphic dna ( rapd ) technique was applied to 12 individuals from each species of the hairtail fishes trichiurus lepturus and eupleurogrammus muticus collected from the yellow sea 50一2 . 44 ) ,群體內(nèi)和群體間的遺傳變異比例分別為69 %和31 % ;群體間的平均遺傳相似度和遺傳距離分別為0 . 9139和o . q861 ;用非加權(quán)配對(duì)算數(shù)平均法( unweightedpair - groupmethodofari山m七tiome即s , upgma )聚類分析的結(jié)果表明,所分析的5個(gè)群體可被分為3個(gè)地理群系,從分子水平上支持了過(guò)去有關(guān)學(xué)者把黃海和東海的小黃魚(yú)劃分為北中南3個(gè)地理群系的觀點(diǎn)。
According to the seasonal variation analysis , the fishing seasons of amberjack ( seriola dumerili ) , yellow - fin trevally ( caranx ignobilis ) , blue - striped runner ( elagatis bipinnulatus ) , big - eyed scad ( trachurops macrophthalmus ) , korean mackerel ( scomberomorus koreanus ) , chinese mackerel ( s . sinensis ) , hairtail ( trichiurus haumela ) , unicorn filefish ( aluterus monoceros ) , angel sharks ( scoliodon walbeemii ) , round scad ( decapterus maruadsi ) and small spot pompano ( trachinotus baillonii ) were significantly affected by different types of set - net construction 其中紅甘? 、雙帶? 、中華馬加? 、薄葉單棘? 、尖頭鮫、銅鏡?及斐氏黃臘?等漁期提前;浪人? 、白? 、高麗馬加?及白帶魚(yú)之盛漁期延后;而白帶魚(yú)及薄葉單棘?更分別于各自的盛漁期成為當(dāng)月份的優(yōu)勢(shì)漁獲物。
