<p>There is provided a method of producing protein feedstock compositions from fisheries waste useful as fertilizer, feed supplements for livestock and aquaculture, and nematodicides. Fisheries waste is comminuted and anaerobically digested by Lactobacillus acidophilus at pH 4.5 to 5.0 and at a temperature between 25 °C and 38 °C, screened to yield a substantially liquid phase, and aged for three months. The composition is then screened to 1.5mm and further aged for two months. The composition may be used directly, or may include an oily phase comprising from 0.5 to 5 % by volume of composition, the oily phase being introduced via a self emulsifying master composition of a degummed vegetable oil and nonionic surfactant. Comminution apparatus for said fisheries waste is also described.</p> |
