Hi Laura,

Here is a quote from the Peaceful Valley  Farm Supply Magazine - other 
sources or manufacturers may have different definitions, I don't know, 
but this may be helpful to start:

"Fish products come in the form of meals, emulsions or hydrolysates 
and/or enzymatically  digested.  

Fish meal is ground, dried fish waste with the oil removed, generallyd 
ried at high heat and is used in soil applications.  It has a high nitrogen 
and phosphorus analysis and is a slow to medium releasing source of 
nitrogen.  For a fast-acting, water soluble fish fertilizer,use fish 
powders, liquid fish emulsion or enzymatically digested hydrolyzed fish.

Fish powders are spray-dried fish materials, dried with heat and turned 
into a water soluble powder.  They can be used for foliar feeding or in 
irrigation systems once put into solution.

Fish emulsion, a popular product used in organic agriculture, is used 
as a soluble fish fertilizer but is usually processed with heat.

Enzymatically digested hydrolyzed fish retains more of the proteins, 
enzymes, vitamins and micronutrients than emulsions, which can be 
processed with high heat and acids.  Heat tends to denature amino 
acids in proteins, making them unavailable to the plants.  Enzymatic 
digestion of fish allows the minerals and amino acids to become 
readily available to plants and makes those nutrients water soluble, so 
you can use them in foliar spraying or through drip and other irrigation 
systems."
