South Australia uses wine slag to produce abalone feed

A lot of waste will be produced in the wine making process. South Australia will use these wastes for the production of feed for aquaculture, and it will have good development prospects. At present, the use of wine waste has produced cheaper and better-efficient feed for the abalone farming industry.

The project is being carried out by the South Australian Research and Development Institute (SARDI) and the wine industry service provider Tarac Technologies in the Barossa Valley. At present, the use of wine waste has produced cheaper and better-efficient feed for the abalone farming industry.

South Australia successfully completed laboratory tests last year, producing 20% ​​Tarac's grape residue ingredients, called Acti-Meal, which will be used in abalone farms in November.

In laboratory tests, the researchers used a laboratory blend to feed the green-lipped abalone, which contained 5-20% Acti-Meal. The study found that the biomass of the green-butter abalone fed the compound feed was increased by 6%, the shell growth rate was increased by 2.9%, and the survival rate reached 100%.

Tarac Technologies CEO Jeremy Blanks said that Acti-Meal products were originally developed for agriculture and hope to be used as feed for cattle, sheep, pigs and other animals. This is the first time that he knows that the wine industry's by-products can also be used. Aquaculture industry.

Blanks said: "We have collected the research done by the South Australian R&D Center. After in-depth discussions, they believe that the use of wine waste in aquaculture has great potential. Australian abalone is considered a treasure in Asia, but globally. The scale of farming within the scope is still relatively small."

The feed also has great export potential and can also be used in other aquatic products such as fish. Blanks said: "To expand sales, we must choose to export, especially in the Asian market. At present, our work with the South Australian R&D Center shows that if the feed abalone is successful, then it can also be used as a feed for the hard-winged fish species. It will be our next step."

David Stone, a professor at the Nutrition and Feed Technology Association of the South Australian R&D Center, said that traditionally, cereals such as wheat, lupine and soybeans have been used as sources of carbohydrates and energy in abalone feeds. Experiments have shown that Acti-Meal can replace them. Some ingredients.
