Comment: I was told once while freshwater fishing that if I leave the fish
hook in the fish it will be dissolved by enzymes in the fish's body. Is
this true ?

Many times I would just cut the monofilament leader and let the fish swim
free with the hook still in him.

In fall 1999, Dettloff's study team caught 14 muskie on single-hook sucker rigs. This time, radio transmitters fixed to the fish had a battery life of at least 400 days, with the potential of going 600 days. Three of the tagged muskie died fairly quickly when released.

In spring 2000, Dettloff and his team began tracking the remaining fish. The news was not good. "By late May at least half of the tagged fish were dead," said Dettloff. "There were about four or five of them still moving around, but...by July they were all dead." Using an underwater camera, Dettloff and his team located several of the fatalities on the lake bottom. Two others washed up on shore and bears dragged them into the bush.

Anglers caught two of the tagged muskie early in 2000. A 34-incher (86 cm) was released by an angler who noticed it was tagged. "That fish looked okay, but was a little on the thin side," said Dettloff. " It ended up dying about a month and a half later." The other muskie was a 42-inch (106-cm) beauty, which Dettloff said weighed about 21 pounds (9.5 kg) when tagged in 1999. When re-caught July 4, 2000, it was emaciated. Although released, it died two weeks later. Dettloff said, "We knew (gut-hooked muskie) were dying, but we hadn't had a chance to see a live fish and observe its health. That fish was as skinny as a rail."

The deaths of those 14 muskie - 100 per cent delayed mortality - convinced him the single-hook sucker rig has no place in an ethical angler's bag of tricks

Note: Sucker rigs are a big hook set into a sucker fish, which is then allowed to swim. The muskie then swallows the sucker fish - and hook - whole.

Aren’t hooks supposed to dissolve to help save fish?

There is no such thing as a “dissolving” hook. “Dissolving” hooks are a marketing creation. All hooks rust and corrode in water. When hooks rust they produce toxins. It appears that it is these toxins that get fish sick, disturbing them from breeding, when that does not kill them.

Never make fun of a man's fish, especially if it is 40 feet tall and aluminum.

It was my impression that the hook(in a lip) would not dissolve, rather the tissue would evenutally soften enough so that the hook ultimately slips out

A hook will corrode away in the proventriculus/gizzard of a bird, and I've seen the radiographs to prove it. Guess that's not quite on topic, though.
