This has led to a trend towards use of other ingredients such as soybean meal, cottonseed meal, leftovers from processing from corn and wheat, legumes, and algae, and an increase in research to find alternatives to fish meal and alternate strategic uses (for instance, in the growth phase, after newborn fish are established). Unmodified fish meal can spontaneously combust from heat generated by oxidation of the polyunsaturated fatty acids in the meal. In the past, factory ships have sunk because of such fires. That danger has been eliminated by
