Under authority of 17 MRSA §2805, the following are adopted as generally accepted agricultural practices for the feeding of fish waste and other liquid-based waste products to swine.
Based on the limited information available, dry ground fish waste is a good source of protein. Depending on the composition of the waste, the total crude protein of fish waste could reach 49.5% (Table 1.)
TABLE 1: Proximate Analysis of Fish Wastes
| Shrimp | Fish | Fish | Fish | Fish | |
| Waste | Waste | Gut | Head | Scale | |
| Moisture | 6.3 | 4.6 | 5.3 | 15.8 | 6.7 |
| Total crude protein | 49.5 | 44.8 | 47.5 | 55.6 | 49.5 |
| Ether extract | 4.3 | 6.7 | 5.9 | 12.1 | 4.8 |
| Ash | 27.3 | 35.4 | 29.1 | 10.1 | 27.0 |

In addition, the amino acid profile of fish waste is very similar to that of industrial fish meal. This and the relatively lower processing cost could make it economically feasible for ground dry fish waste to replace commercial fish meal as a feed ingredient in many livestock and poultry rations.
