The best extracting process of gelatin from ballomfish skin was studied. To observe the effect of sodium hydroxide and vitriol and their action time to the extracting efficiency and quality.The results showed that the ballomfish skin was marinate with 8 times volume of 0.2%sodium hydroxide and 0.3%vitriol successively. Then the factors of the volume of water, the time and the temperature of extracting to the influence of the extracting rate were observed. The results showed that the best extracting technology was 4 times volume,the temperature was 60℃,and two hours one time.

The petroleum hydrocarbon pollution level was evaluated in the south sea area of Zhoushan, according to the investigation result of water, surface sediment and marine animals in Aug.2008 ~Jun.2009, the results showed that in water, the average concentrations of petroleum hydrocarbon accorded with the first and second class of the water of National Standards. The relativity between Petroleum hydrocarbon and pH, salinity, temperature, DO, COD was very small. The concentration of petroleum hydrocarbon in winter was least, other seasons had no evident difference. The quality of surface sediment and marine animals were well.

In order to create a economic and efficient sediments aquaculture Babylonia in cement pond, two methods of sanded sediments on bottom were tested to compare the results of farming Babylonia. The results showed that the growth of B. aerolata and B.formosae habei was not significant difference same way sanded,under the breeding water temperature and the stocking density similar cases in same season different years. When the methods of sanded sediments were left the bottom sanded, that the growth rate of body weight daily of B. aerolata and B.formosae habei, was higher than which affixed to the bottom sanded 85.0% and 68.6%, the growth rate daily of shell height was higher than it 56.1% and 45.4%. The methods of leaving the bottom sanded sediments was effective technological measures of Babylonia aquaculture to build economic, efficient sediments in cement pond.

Fugu flavidus is good nutritional value and multi-purpose, which is wide-used in different fields. Its culture in mud ponds will add culture species and improve its profits in mud culture. The paper will provide a technical guide of its culture based on daily management, feeding and water quality management, disease preventing and cure. Fugu flavidus grows quickly in mud ponds with weight-growth rate of 0.658g/day , and the survival rate is 86.7%. There is two feeding peak with dawning and dusk, the time of feeding is about 1-2hours, and the amount of feed of dawning accounts for 1/3 of total daily amount. The Daily feeding rate is 2.0～3.0% in early-stage, and 1.5～2.0% in late-stage, which have to be modified in abnormal condition. The amount of water exchange is 20%～40%. According to the principle of “prevention is first combined with treatment”, the disease will be control, prevented and treated mainly with the management of water quality, feed and drugs using.

The artificial propagation were done under the different temperature of 20℃, 23℃, 26 ℃, 29 ℃ and 32 ℃. The results show that under the conditions of 26 ℃, The daily fecundity of Nothobranchius Guentheri was the largest, and the fertilization rate was the highest , 26℃ is the best temperature to Nothobranchius Guentheri reproduction.;Ten mating pattern of broodstock were studied during the breeding , we found that when the mating pattern were 4♂ +1♀、2♂+1♀ and 1♂+ 1♀ ,the daily fecundity were higher, and the fertilization rate of which were higher too, 4♂+1♀ 、2♂+1♀ and 1♂+1♀ were the best mating pattern to Nothobranchius Guentheri production; we also observed the spawning period of three batches of broodstock for 20 weeds under 25~26℃, it showed that 15 to 17 weeks the daily fecundity of Nothobranchius Guentheri was the largest, the daily fecundity was 20 to 30eggs/tail.

Abstract：With the development of industry and urban expansion, coastal, suburban excellent fishing areas and beaches be taken up in great quantities, traditional breeding areas are squeezing out, development of industrial, tourism, shipping industry which are closing to port or sea and fishery development of increasingly sharp contradiction; And these industry becomes more and more serious pollution caused by dumping, plus alongshore, poor management, marine environment quality is gradually decline, intensifies the fishery disputes occur repeatedly. These contradictions directly affect the fishermen's production and life, even affect the mutually harmony and stability. In order to reduce and ease of use of the sea disputes, must strengthen the use and management of sea areas in the meanwhile, overall arrangement with the sea for industries; Especially with the sea fisheries shall be with legal protection legislation counterpoising truly fishermen use of the sea rights; And shall establish fishermen old-age security system; Audit strictly with the industry can produce pollution, so as to ensure the sea with the fisheries no pollution and fishery waters of ecological environment is not compromised, thus with sea and fishery production and life of the fishermen's coastal areas, in order to maintain social stability.

We putted 32000 juvenile fish of Acipenserschrenckii Brandt which were 10cm in average total length into six different cages to culture in May 10th, 2010. The culture area was about 600m2 and the density of breeding was about 53 individuals/m2. The total production of Acipenserschrenckii Brandt was 24729kg after 383d breeding and the average production was 41.22 kg/m2. The total value of the product was 858326 yuan and the average value was 1430.54 yuan/m2. In our experiment the feed coefficient was 1.77, the pure profit of our project was 352802 yuan and the proportion of investment/production was 1:1.7.
