* Directions for Preservation of Fish 
-3- 
Cautions, Cont. 
2. Do not crowd the fish in the containers, because an 
over-crowded condition causes the fish to be hardened in absurd 
shapes and also they are very likely to spoil for lack of enough 
preservative. 
3. All fish over three and one-half inches in length, es- 
pecially soft-bodied fish, should have a small slit made in the side 
of their abdomen. The slit should penetrate into the abdominal cavity. 
It is best to inject all fish over one foot in length, filling the body 
cavity with preservative. 
4. As a rule, fish should be left in the preservative for one or 
two weeks, depending on their size, before wrapping for shipment . 
5. Always place a label, with the essential data, in each jar 
or package of fish.
