Due to their strong piscivorous habit, the exotic glass fish may cause damaging effects on the aquatic ecosystem and native fish populations.

由於暹罗副双边鱼对於鱼苗有很强的掠食性，因此该族群对於日月潭水库的生态系统可能会造成很大的危害。

The researchers say the risk for humans who may occasionally eat fish from the streams is fairly low and they compare the mercury levels in most of the larger piscivorous fish they analyzed to that found in cans of store-bought tuna.

研究人员说，该风险对于人类的人有时会吃鱼，从溪流中，是相当低的，他们比较汞水平，大部分规模较大的食鱼鱼类，他们分析发现，在罐的商店买金枪鱼。

Here, we took demonstration study of the ecological impacts of disconnection from the river on fish recources in Zhangdu Lake. Our results showed that:(1) Fishery mode changed and the rate of wild fishery production changed from 95% in 1949 to less than 5% in 2002.(2) Fish species have decreased from 80 in 1950s to 52 at present, and the rate of migrant and potamic species decreased from 50% in 1950s to 30% at present.

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30

Orange-spotted grouper is a benthic protogynous marine fish with sex inversion. It is one of the most important culturing fish in the southeast of Asia. As in other vertebrates, its growth is mainly controlled by growth hormone . Few data are available concerning the regulation of GH in grouper. In this paper, the regulation of growth hormone release from pituitary of orange-spotted grouper and its mRNA level was determined by radioimmunoassay and RNase protection assay.

应用分子克隆技术，构建了斜带石斑鱼生长激素(Growth hormone，GH)基因重组质粒，在大肠杆菌细胞中获得高效表达，亲和层析纯化斜带石斑鱼GH融合蛋白做为抗原，免疫家兔制备特异性抗体，通过酶联免疫实验、放射免疫测定、离体脑垂体静态孵育和液相杂交／核糖核酸酶保护试验及化学发光检测技术，研究了斜带石斑鱼GH分泌及其mRNA表达的调控机制，对于斜带石斑鱼的生长、繁殖、人工养殖等具有重要意义。
