Scientific integration of Zhuhai's aquatic resources to enhance the competitiveness of aquaculture industry

Introduction: since the establishment of Zhuhai, the aquaculture industry in Zhuhai has developed steadily and has become the pillar industry of the rural economy in Zhuhai However, the development of aquaculture in Zhuhai mainly depends on the continuous expansion of production scale The resource output rate, capital and labor input-output rate are still low, and the overall production level is relatively backward It is mainly reflected in: first, the old infrastructure and backward business model Most of the existing 300000 Mu ponds were excavated in the 1980s and early 1990s Due to the long service life, the bottom of the pond is full of silt and residual bait, the water in the pond is shallow, and the water quality is very easy to deteriorate It can only be used to breed four low-value varieties such as domestic fish and tilapia, with low breeding yield and poor efficiency At present, most of these ponds are developed by individual farmers, with scattered management, low scale and industrialization, and weak ability to resist risks Second, the development and construction of aquaculture sites lack of scientific and unified planning, and the layout is unreasonable Some see rivers and ditches, see water and dig ponds, blooming everywhere, disorderly and full of ponds; some blindly pursue the cultivation area, a small ditch is responsible for the drainage and irrigation of 56000 Mu pond, of course, fresh water is in short supply; some are indiscriminate, cross pollution is serious in the cultivation process, and diseases occur frequently In recent years, the losses of aquaculture production caused by diseases in our city are up to tens of millions of yuan every year Third, the production of aquatic seedlings is backward and the supply of seedlings is seriously insufficient Most of the 56 billion fry and shrimps needed each year are supplied from other places, and the number of fry produced in this city is less than 20% of the total Fourth, in terms of aquatic feed and fish medicine sales, up to now, most of them are still operated by the masses spontaneously Due to the lack of standardized management, fake and fake drugs flooded the market, and even banned drugs with serious residues and environmental pollution are commonly sold and used And the vast majority of operators do not have the corresponding professional knowledge, the phenomenon of overdose and wrong drug use is very common In addition, the existing test standards are low, and the means and methods can not keep up with the needs of development, which makes the deterioration of aquaculture environment in our city increasingly serious In order to further improve the competitiveness of aquatic products in our city, successfully participate in international competition and promote the healthy development of aquaculture industry, the following suggestions are put forward: first, strengthen the education of scientific knowledge popularization and technical training, and constantly improve the level of aquaculture technology of producers At the same time, an aquatic resources monitoring agency should be established as soon as possible Monitor the aquaculture environment of the whole city, grasp the changes of aquaculture environment in time, and guide the production scientifically 2 On the basis of a comprehensive investigation of the aquatic resources, we should make a scientific overall plan for the development of aquaculture Give full play to the geographical advantages of the estuary area and the neighboring Hong Kong and Macao, aim at the international market in terms of production layout, take the marketable varieties in the international market as the main target, and vigorously develop the estuarine characteristic fishery and export-oriented foreign exchange earning fishery The municipal government shall urge all districts and villages to make their own development plans on the basis of the overall planning of the city The planning and design of each town and village shall be carried out with the participation of aquatic scientific research department and demonstration by aquatic experts As far as possible, we should concentrate the scattered individual management, form the scale production and realize the scale benefit 3 As soon as possible, we should reorganize the ponds with unreasonable layout, collapse of the pond foundation and shallow water, carry out renovation and treatment, further improve the water quality conditions of the breeding environment, promote the improvement of the breeding efficiency, and avoid the waste of aquatic resources The government can choose the villages with better conditions to carry out the pilot project of pond renovation The cost of renovation and renovation shall be mainly borne by the municipal government, and each district, town and village shall provide a little solution Then sum up the experience and promote the re planning and renovation of aquaculture ponds in the city If the city's more than 300000 mu of breeding grounds are all scientifically planned and renovated to meet the standards of scale, industrialization and modernization, the breeding output will increase by 30% (about 30000 tons), and the output value will increase by 50% (about 600 million yuan) 4 To formulate preferential policies, exempt the production of aquatic seedlings from tax, and grant preferential tax policies to the projects such as the introduction and cultivation of new varieties, the promotion of scientific and technological achievements, and the export and processing of aquatic products Especially for the projects of deep processing of aquatic products, more preferential policies should be given in terms of land use, fees and taxes than other projects 3UD
