The growth hormone gene of Southern catfish is growth hormone cDNA full length sequence of Southern catfish obtained with hypophysis mRNA as template and through RT-PCR, 5'RACE and 3'RACE method.

本发明公开了南方鲇的生长激素基因，其特征是它以脑垂体的mRNA为模板经RT-PCR，5'RACE和3'RACE的方法得到南方鲇生长激素cDNA全长序列。

The newt swims by means of its feet and tail; and its tail resembles that of the sheatfish, to compare little with great.

Thee isoenergetic diets containing 0%, 15% and 30% gelatinized corn starch were formulated as control, middle level and high level carbohydrate diets, respectively. The juvenile southern catfish, Silurus meridionalis Chen (50.5±0.6g) were acclimated with control diet for l5d at 27.5±0.5t. Activities of glycolytic key enzymes (HK, GK and PFK-l) and the serum glucose concentrations in the southern catfish respectively fed with the three diets were examined, at 3, 6, 12, 24 and 48h after feeding.

配制含0%、15%和30%糊化玉米淀粉的等能饲料分别作为对照、中水平和高水平碳水化合物饲料，以体重为50.5±0.6g的南方姑幼鱼为实验对象，在水温27.5±0.5℃的条件下以对照饲料驯化15d后，分别测定了以三种饲料投喂的南方鲇在餐后3、6、12、24和48h的己糖激酶、葡萄糖激酶和磷酸果糖激酶(PFK-1)的活性和血糖水平。

Siluriformes belonging to Ostariophysi, Teleostei, is a group of fishes that are mainly lived in freshwater and broadly distributed in all continents.

To compare the difference of drain and intake water then converse with biomass in sweetfish and walking catfish's grow-up pond. The ammonia-N, nitrate-N, nitrite-N and phosphate were 383.7, 208.99, 21.62 and 119.03 mg/kg in sweetfish's pond, respectively.

水中营养盐部分香鱼与胡鲇池换算流水量与生物量后，香鱼每增长1 kg，它所产生之氨氮、硝酸氮、亚硝酸氮及正磷酸酸盐的量分别为383.7、208.99、21.62和119.03 mg；胡鲇每增长1 kg则分别为68.76、5.72、2.44及13.80 mg。
