The invention relates to methods and compositions for the recombinant production of animal protein for use in animal food, particularly pet food.

The present disclosure provides a recirculating aquaculture system comprising a) a wastewater treatment system and b) a polyhydroxyalkanoate (PHA) production system. In particular, poly(3-hydroxybutyrate) (PHB) can be utilized as the PHA in such a system. Methods of treating wastewater for reuse by contacting the wastewater with one or more zeolites to remove material from the wastewater and reusing the treated wastewater are also provided as well as methods of producing a PHA such as PHB from organic waste. Moreover, food compositions comprising a PHA biomass as well as associated methods are also provided.

The present invention relates to a quick-sinking fish feed in the form of pellets. It has been found that pellets, the diameter of which is <4 mm, have difficulty in sinking, especially in the cold time of the year when the density of water is at its maximum. The reason why the feed does not sink is its low intrinsic weight and the too high surface tension. If the fish does not have time to catch the feed, the pellets will be moved by the waves of the sea through the meshes out into the free water. This problem can be solved by loading or coating the fish feed pellets with an oil comprising at least 10% microbial oil.

This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by using a mechanical device to separate the solids from the liquids based on a density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.
