There are 2 ways of answering your query
1. Hunting or catching fish for sport and letting it die for trophy, and not consuming it as food is haram. Same rule applies as land animals.
2. Now hunting fish like approved by modern societies is acceptable where you tackle , weigh and return it to the water so the fish does not die.

A study has found that, even when caught on a hook and wriggling, the fish is impervious to pain because it does not have the necessary brain power.
The research, conducted by a team of seven scientists and published in the journal Fish and Fisheries, concluded that the fish’s reaction to being hooked is in fact just an unconscious reaction, rather than a response to pain.
Fish have already been found to have “nociceptors” - sensory receptors that in humans respond to potentially damaging stimuli by sending signals to the brain, allowing them to feel pain.
However, the latest research concluded that the mere presence of the receptors did not mean the animals felt pain, but only triggered a unconscious reaction to the threat.
The latest findings contradict previous research, which suggested that these nociceptors enabled the creatures to feel reflexive and
In an earlier study done by the University of Edinburgh, rainbow trout were injected in the lips with an acid solution.
Researchers pointed to the fish’s behavioural changes, such as them rubbing their mouths on the gravel, and moving in a rocking motion similar to that seen in stressed mammals, as evidence of pain.
However, the new research, which reviewed a series of studies conducted over the years, discovered that only an extremely small number of “C fibres” - a type of nociceptor responsible for pain - can be found in trout and other fish.
Professor James Rose from the University of Wyoming in the US, who led the study, also found that the fish brain does not contain the highly developed neocortex needed to feel pain, so do not experience it in any meaningful way like humans.
He concluded that fish are able to experience unconscious, basic instinctive responses, but that these did not lead to conscious feelings or pain.
The trout’s reactions in the earlier study were therefore not ones of discomfort, as they lack the capacity to experience it, Prof Rose found.
The new research also referred to a study done on fish which were caught with a hook and then released.
The fish resumed feeding and normal activity immediately or within minutes and went on to show good long-term survival, which indicated they had not experienced pain.
Professor Robert Arlinghaus, one of the team’s researchers, said the presumption that fish feel pain has hindered scientists for decades and has stigmatised anglers.
“I think that fish welfare is very important, but I also think that fishing and science is too,” he said.
“There are many conflicts surrounding the issue of pain and whether fish can feel it, and often anglers are portrayed as cruel sadists. It's an unnecessary social conflict.”
Mark Lloyd, head of the Anglers’ Trust, said: “This debate about fish feeling pain has always been a red herring, so to speak.
“Anglers care passionately about the protection of fish stocks and do more than any other group to protect and improve freshwater and marine environments.
“Modern fishing tackle and techniques mean that fish which are released have an excellent survival rate and if fish are to be eaten, then angling is by far the most sustainable way of catching them.”
An RSPCA spokesman said: “There are a number of studies which we believe provide enough evidence to show that fish do feel pain and this remains our view.”
