fish hold

[Rscottdds]

What's the best way to deal with ice, blood and the mess that ends up in the fish hold? It has a drain hole but I don't want all that stuff running down under the gas tank into the bilge. On my previous boat I had a macerator pump installed under the drain hole that would suck it dry. Cant do that here as there is no access. I was thinking of getting an insert or fish bag. Any thoughts?
