Fine fish food

人类每年消耗大约90至9500万吨新鲜捕鱼。在不久的将来，较大的渔获量将不可能因为鱼类库存处于极端限制。然而，对鲑鱼，金枪鱼，海低音和鳕鱼的需求随着越来越多的全球人口而增加。这些鱼也被越来越呈现为更健康的肉类替代品。出于这个原因，自20世纪50年代以来，从20世纪50年代以来，鲜水和咸水鱼类和海鲜等海鲜在水产养殖中升高，趋势不断发展。该行业主要位于亚洲，南美洲和欧洲，是食品行业最迅速扩大的，增长率为5至6％P.a.总产量为7300万吨鱼。水产养殖业正在提供越来越多的鱼类和海鲜 - 但它也呈现出巨大的挑战，从动物的适当营养和健康到耕种环境的影响。乐动体育买球作为一个例子，采购新的可持续原材料以支持水产养殖生长是水产养殖的主要挑战之一。水产养殖饲料主要与蔬菜原料来源一起制定，但鱼粉仍然是一种不可或缺的成分，保证了大多数养殖属性的良好饲料适口性和营养价值。乐动体育买球 Fish meal is manufactured from fresh fish – about 15 million tons of wild-caught fish is used for this. However, its worldwide production has remained stable for many years while the aquaculture industry, and consequently the demand of fish meal, is growing. This model cannot work in the long term, and many experts agree that new raw material alternatives must be found.

开发标准化方法

Diana Pet Food therefore founded a small business unit in 2003 to address this issue. Vincent Fournier, Head of Research and Development at Diana Aqua, has been there from the very beginning. The business unit develops and produces feed ingredients for aquaculture and now has 140 employees at sites in Europe, Asia and Latin America. The scientist, who has a doctorate in fish biology and nutrition, started the first attempts at creating the perfect fish feed 14 years ago. “We had a number of tasks right from the start: reducing the amount of fishmeal in fish feed, making it both palatable and nutritious while supporting fish health,” he says during a tour through the company’s test center in Brest, France. It is on the outskirts of the capital of Brittany, just a stone’s throw from the Atlantic. The 44-year-old established the facility on the grounds of a French research institute and then developed the testing protocols, allowing him and his team to assess various feed supplements in European sea bass. “Among other things, we experiment the palatability of our products here – in accordance with strict standardized methods – by measuring feed intake and by observing the growth of the fish.” Another emphasis is on how healthy the animals are when they are fed with diets containing no or low fish meal and the Diana Aqua products on a long term (8-12 weeks). Diana Aqua has developed similar testing centers in Ecuador and Vietnam in order to validate product performance in different species and in different breeding conditions.

通过在数年的研究e Vincent Fournier was ready to test his first products. “We had to find out what makes feed particularly attractive, nutritious and healthy for aquaculture fish. The key to this is the peptide content in the marine raw materials,” says Fournier. In order to produce and concentrate these, the researcher fine-tuned a hydrolysis process. In this process, peptides are released with the help of enzymes, special pH values and clearly defined pressure and temperature levels. The process is a bit like a predigestion process that makes it easier for the fish in the aquaculture to consume the feed. “This hydrolyzed raw material is digested at 99 %, while most of the fishmeal are only digested at 90-92 % or even lower.” The second key point of the research is the raw materials. Vincent used leftovers from food production that would otherwise go to waste, such as tuna viscera, tilapia frames and shrimp heads, to yield the most value possible from them.

它是创建第一个产品的冗长路径。“没有认识的标准化方法，用于评估产品适口性能，”文森特四维表示，为行业设定了一个不满的里程碑。建立在他的第一个产品的基础上，已经创建了AP31,13，其作为液体或粉末出售。每年都有更多。例如，一种特殊产品增加了鱼类对病原体的免疫力和抗性，这意味着它们需要更少的药物。另一种产品改善了鱼的肠道健康 - 食物更好地吸收，鱼类更耐疾病。

研究新销售市场

下一步是什么?文森特·珀西answer. The engineer with an emphasis on agriculture is the Europe General Manager at Diana Aqua. He is on the lookout for new sales markets based on the research. “For example, we saw that some larger peptides also have bioactive effects and activate processes in the animals’ bodies.” One product, for example, helps the aquaculture fish be less stressed in changing water temperatures and fish continue to eat normally despite strong water temperature changes. Another product is a feed ingredient that is intended to increase the feed intake of a particular fish. “The quicker the animals grow to full size, the less they are affected by diseases,” says Vincent Percier. A third project is focused on how the peptides of different fish types function after hydrolysis. “Tilapia hydrolysates can be used as a raw material for raising gilthead seabream because the peptides support their digestion and thus also their growth especially well.”

Vincent Percier is also in contact with suppliers. “We work together with the largest tuna processor in Thailand, for example. We buy the innards, which are left over after filleting, from them.” The process is so finely tuned that the byproducts are used in Diana Aqua production just two hours after processing.

Vincent Percier的另一个关键问题是可持续性。乐动体育下载Diana Aqua产品的意思是，用于人类的鱼粉生产和食品生产之间的野生捕捞鱼类较少。“我们真的可以在那里产生影响力，”Percier说。“例如，如果用20％的鱼粉包含营养和适口性的饲料，我们可以通过在配方中加入3％的水解产物来保持相同水平的饲料性能，只有10％的鱼粉。乐动体育买球另一个效果：因为饲料被消化得很好，鱼也减少了排泄。相反，这对环境有益，因为水中的沉积物较小。“
