Jon the best time to cook and eat seafood is five to 10 days after it’s been caught. “It’s not that you can’t eat it, it’s just you have to wait for it to mature,” he .

Can you eat fish with rigor mortis?
The effects of machinery, stress, and storage temperature are some of the factors that affect how much a pre-rigor mortis fillet will shrink. While fish is in a state of full rigor, it should not be processed. This is because the fillets will not shrink as much as they would if they were fully rigorously processed.
When fish are frozen, they can be stored for a longer period of time than when they are fresh. Frozen fish can also be frozen at a lower temperature than fresh fish.
However, this does not mean that the frozen fish will have the same quality of flavor and texture as the fresher fish, because of the difference in the temperature at which fish is frozen and the time it takes to thaw.
In general, fish that have been frozen for more than a few days will be less flavorful and more tender than those that were frozen within a day or two.
How long can you keep a dead fish?
You can keep the fish for up to a week if you store them on ice or in the refrigerator. If you store the fish in a cool, dry place, it will keep for at least a month.
What happens to a dead fish?
Immediately after death, most fish are slightly denser than water. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. The corpse will float like a balloon if enough gas builds up in the body.
This is why it’s so important to keep a close eye on your fish when they’re alive. If you’re not careful, you could end up with a dead fish floating in your aquarium.
Is fish eating fish cannibalism?
According to smith and reay, cannibalism is most common among piscivorous fishes. According to the present review, cannibalism is most frequently observed in fishes with diet containing various proportions of aquatic insects, crus-like crustaceans, mollusks, and other invertebrates. Cannibalism has been observed in a wide variety of marine and freshwater fish species, with the most commonly reported cases occurring in the Atlantic and Pacific Oceans.
In some cases, the consumption of a large number of prey items has resulted in death of the victim, while in others, only a few items have been consumed. It has also been reported in some species of sharks and rays, as well as in other marine fishes (e.g., pinnipeds) (Reay and Smith, 1991).
In addition, it is possible that the occurrence of cannibalistic behavior may be due to a combination of factors, such as predation by other fishes or the presence of parasites, which may cause the fish to eat more than they need to survive.
Why do fish get stiff?
The mechanism behind this is muscle contraction due to shortage of ATP (adenosine triphosphate). When most of the muscle fibers are contracted, the rigor will be completed. In the case of a fish that has been dead for a long period of time, the muscles will not be able to contract properly. This is the reason why fish can become stiff after they are dead.
Why do fish still move after death?
Very fresh fish still have their neurons fully intact, even though they’re dead. As soon as you add a bit of salt to the exposed muscles, the neurons are triggered and the muscles contract. Very dead fish will move about until they use up all their energy, and then they die.
“So what’s the point of all this?” I don’t want to have to worry about it getting stuck in my intestines, or getting into my blood stream or anything like that.
What is right mortis?
Rigor mortis is a chemical change resulting in a stiffening of the body’s muscles following death, resulting from changes in the myofribrils of the muscle tissues. The body becomes limp after death and can’t support its own weight.
The most common cause of death is cardiac arrest, which occurs when the heart stops beating and the blood supply to the brain is cut off. Other causes include asphyxiation due to lack of oxygen, suffocation, and strangulation.
What are the 3 stages of rigor mortis in fish?
The rigor in fish starts at the tail and goes along the body towards the head until the whole fish is stiff. The fish can remain rigid for an hour or so, depending on a number of factors, such as temperature, water quality and other factors.
A fish with a weak tail will not be able to keep up with the rest of its body weight and will be unable to swim as well as a stronger fish. This is why it’s important to have a strong tail to help the fish maintain its balance and keep it in the water.
Can I flush a dead fish down the toilet?
Dead fish are not on the list of flushable items because they are not designed for disposing of undesirable materials. Human waste, water and toilet paper are the only things that are supposed to be handled by a sewage system. It can lead to serious health problems if it gets stuck in the pipes.
