Why would you? Most land based plants are not a good fit for fish food.
I was reading a couple of articles stating that its being used in farm raised fish. Look fish food manufacturers are using a ton of non marine food in thier mixes

Fish farms may be using it because it is a good alternative to other more expensive ingredients. When going through tons of feed on a commercial scale, manufacturers look for cost effective alternatives. It is also likely it is for omnivorous fish that may not need as much high quality protein (ie tilapia, catfish etc...). Most marine fish require a higher protein and essential amino acid level so meaty foods tend to be better.

I can’t see it providing any benefit to your tank inhabitants. It may add some fiber? ;Smuggrin Are you looking at a powder to mix with their food?
Was thinking about it

I understand that and use clams, muscles oysters, shrimp, fish eggs, flounder/ cod, freeze dried plankton, mysis and squid. I was thinking of my tang and foxface. Right now I feed nori.

I tend to think of a lot of land based foods (sorghum, soy, wheat, etc.) as fillers and binders used in the fish food making process. What's the nutritional breakdown for hemp? How does it compare to that of seaweed?
Those are good questions

If hemp has a significant protein source you can use it as a fish meal replacement in conjunction with other ingredients. I work in a lab where we have done a lot of research on sustainable fish meal alternatives in commercial marine finfish diets. There are a few plant based products that can help replace some of the fish meal but it starts negatively impacting the fish if you go too far. We’ve done a good amount of work with soybean and cotton seed meal and you can replace a significant amount of the fish meal with them. If hemp has similar nutritional qualities it may work also.
With that said, I wouldn’t feed my reef tank soybean or cottonseed products, they are not a complete diet, you’d have to add a lot of extra stuff. Marine algae’s have usually have much higher essential fatty acid profiles so they would be a better choice.

Thank you. I appreciate it. Its being used in commercial fish farms to help control coasts and something other than fish meal for sustainable farming. I'll stick to feeding what I am.
