Facing the escalating price of fishmeal, many feed enterprises feel helpless and disoriented. Can we decrease the proportion of fishmeal in feed? How to determine the amount of fat in feed? How to balance the ratio of amino acids? The reports will be inspiring by explaining the formulation of the popular species such as California perch, Channa argus argus, large yellow croaker, etc.

    Quality management of raw material of special aquatic feed

    Dr. Zhenxiong Qi    【Deputy Director of Guangdong Haid Animal Husbandry and Fisheries Research Center】

    Raw material for feed is a major cost. Manage feed is managing raw material. It is important to make the management of raw material well, especially for the high fat perishable special aquatic feed, such as squid liver paste, shrimp shell powder and DDGS etc. But there is no uniform standard for the management as lack of the corresponding national or industry standards. How to operate to ensure the quality of raw material? In this report, lecturer will share feed raw materials quality control procedures and practices of Haid group for draft brother.

Is there any wrong with the traditional formulation technology? The research progress of Penaeus vannamei at home and abroad, aquaculture development experience in Southeast Asia and the market response after formulation adjustment give the answer. In this report, the lecturer will discuss the direction of Penaeus vannamei feed technology with draft brother.

    The important influence on aquatic feed of biogenic amines or gizzard erosion in fishmeal

    Dr. Yong Yang    【Technical Director of Hinter Biotechnology Co., Ltd.】

    In recent year, we face with the high incidence of disease and change color of fish, especially in 2006. What’s the reason? Is heavy metal exceeded? Or fat oxidized? Or vitamin lacked? Or mycotoxin infected? All these were excluded. The only reason was a batch of problem fishmeal. The phenomenon is likely to the black vomiting event which puzzled the global poultry industry a few decades ago. Is this a coincidence? According to a mass of data, the lecturer will make the prediction and provide the new consulting of use and quality control of fishmeal.

    Service marketing based on the aquaculture chain

    Zhenhong Ding    【Professor of Guangdong Haid Animal Husbandry and Fisheries Research Center】

    Competition of feed industry has become increasingly brutal. As serious excess capacity and a new upsurge of investment in this industry, aquatic feed sales will face greater pressure. Does strengthen the relationship work? Or guiding ideas for scientific culture? Improve the cost and ensure the quality or increase the discount to be more attractive? There are so many tricks that hard to handle with. What’s measurements should we take? Let’s listen to the Zhenhong Ding’s opinion.
