Stone grouper refers to various species within the subfamily of grouper in the family Serranidae under the order Perciformes.They are commonly found off the coast of China, in the West Sand Islands and the South Sand Islands, making them an important large or medium-sized warm-water sea product with significant economic value.This fish prefers quiet environments, fears waves, likes warmth but dislikes cold, and dislikes turbid water.They can often be seen at depths of 10 to 15 meters in the seabed, particularly in rocky crevices and coral areas.Smaller individuals are active in shallow waters, they move around frequently and are easy to catch;Larger individuals prefer quiet environments, live deep and sequester themselves, often staying in caves or deeper waters.Today, we will provide a detailed introduction to the types of stone grouper.

Types of stone grouper

Stone grouper belongs to the order Perciformes with an elongated oval body slightly flattened laterally.They have large mouths with accessory upper jaws, sharp teeth that are sometimes enlarged into canine-like teeth.Their bodies are covered in small ctenoid scales which can often be buried beneath the skin.The dorsal and anal fins are well developed.The caudal fin is rounded or slightly concave.Their body color varies greatly, often appearing brown or red with stripes and spots. They are warm-water large to medium-sized sea products.Common species include East Starfish Grouper, West Starfish Grouper, Thai Starfish Grouper, Leopard Grouper, Rat Tail Grouper, Tiger Grouper, Green Grouper, Spotted Grouper, Money Grouper, Cedar Grouper, Su Rat Tail Grouper, Red Sesame Seed Grouper, and Giant Grouper.Below are the characteristics of four common stone grouper:

(1) The point-dashed stone grouper has a short blunt snout, 8-11 dorsal fin spines, no black spots on the base, five inconspicuous horizontal bands on the sides of the body, and scattered spots on the sides and fins.This tropical mid-to-deep water fish prefers to live in rocky areas with sandy bottoms. It is a valuable species in the South China Sea.It is fierce and primarily carnivorous, feeding mainly on fish, shrimp, crabs; it may even resort to cannibalism when hungry.They can survive in seawater with salinity ranging from 11-41‰. The most suitable water temperature is between 22-28℃, their appetite decreases below 18℃ and they lose balance below 15℃.They can be raised in net cages.Their distribution includes the East China Sea, South China Sea, etc.

(2) Red spot stone grouper has 16 dorsal fin spines with a black spot on the base. Their body is brownish-pale yellow, and their head, body, and odd fins have many orange-yellow spots (which turn white after preservation).They are temperate mid-to-deep water fish.Adults feed on fish, shrimp, crabs. They are hermaphroditic with females maturing first. Most mature by age 3 when their body length is 231-295mm and undergo sex reversal from female to male when reaching a body length of 250-400mm at about 6 years old (some 5 years).They produce up to 250,000 eggs with peak spawning occurring between May and June. The optimal water temperature for spawning is around 22-24℃.Their meat is delicious and can be exported; they are valuable fish species that have been successfully bred in captivity and raised in net cages or shallow seas.They can be found in the Taiwan Strait, East China Sea, South China Sea, India, and Japan.(3) Green stone grouper has several orange-red spots on its underside. It also has six dark brown vertical stripes with the third and fourth stripe being the widest apart;

Only the tail fin has spots.They are warm-water mid-to-deep water fish.Juveniles feed on plankton while adults feed on fish, shrimp, crabs.They are hermaphroditic with females maturing first. Males mature when their body length reaches 250-400mm at about age 6 (some 5 years).The absolute fertility is between 80,000 to 250,000 eggs and the peak spawning period is from late May to July. They begin laying eggs when water temperature reaches 20℃, with a peak of 22-24℃.They require an incubation time of 23-30 hours at 22-25℃ to hatch larvae.When raised in captivity, they are popular for farming and can be grown in net cages or shallow seas. Their meat is delicious with high economic value.They can be found in the Taiwan Strait, East China Sea, South China Sea, Japan, etc.(4) Oblique line stone grouper has an elongated body that is brownish-pale on its head and back, with a white bottom stripe;Numerous orange-brown or reddish-brown spots are distributed in the middle of the head, body, and fin rays;

There are five large irregular black spots that fork towards the abdomen;The first spot is below the first dorsal spine, while the last one is on the tail stem;Two more black spots are at the junctions between the operculum and the second gill cover.When exposed to air, orange spots turn brown; in preservatives, they become blurred.This fish often resides along continental shores or large islands. It can also be found near river mouths up to 100 meters offshore.The main breeding period is from March to June.Females mature when their length reaches 25-30cm at age 2 or 3 (females) and usually undergo sex reversal around 75cm in body length.A female fish of 35cm is estimated to produce about 85,000 eggs while a 62cm fish can produce approximately 290,000.How to Cook Stone GrouperFried Garlic Stone Grouper

Selection and Storage of Stonefish

Stonefish are warm-water nearshore bottom-dwelling precious fish distributed in the western North Pacific; China mainly produces them in the South Sea and southern East China Sea.The flesh is rich, delicate, and tender, with abundant nutrition.

Common varieties include red spot stonefish, salmon eye stonefish, green stonefish, cloud pattern stonefish, and net pattern stonefish, etc.

Due to its fine, white, tender flesh similar tochicken meat, it is also known as "sea chicken".Wild stonefish have a milder taste with high activity; the fish color changes significantly and has obvious patterns, but they are more expensive.Cultivated stonefish, though of average quality in texture, are uniform in size, soft, very fresh-tasting, and less costly.Choose plump fish that feel firm to the touch when pressed for optimal quality.The flesh is firm and evenly distributed; the head, middle section, or tail all taste good. The meat in the middle part is particularly tender and large, with excellent texture and freshness, while the tail is also fresh and delicious.Look for fish skin with a glossy appearance, scales not fallen off, clear eyes, tight flesh, and fat abdomen as indicators of quality.

No need to buy large stonefish; a fish about 30 cm long is ideal. For frozen stonefish, choose complete and vibrant fish.Not fresh stonefish are easy to identify by their color fading significantly.Stonefish are carnivorous and require very high-quality feed.Without good feed, quality seedlings, and excellent water conditions, it's impossible to raise quality stonefish.Some farmers stuff the stomach of the fish with small miscellaneous fish before selling them for higher prices; be cautious when selecting.For consumption, all ages can enjoy it, but 80-100 grams per meal is appropriate.

Patients with gout should avoid stonefish.Although there are fewer dietary restrictions for eating stonefish, here, we want to remind everyone about some fish-eating taboos.1. Eating fish gallbladder for detoxification can backfire and cause poisoningFish bile is a traditional Chinese medicine used to treat eye redness, sore throat, etc.There's also the belief that eating fish bile can clear heat and detoxify, brighten eyesight, and stop coughs.However, experts point out that fish bile contains strong toxic components such as "Na-2-sulfonated ichthyol" which are not destroyed by heat or alcohol. Thus, no matter if the gallbladder is cooked, raw swallowed, or consumed with alcohol, poisoning can occur.Poisoning from eating fish bile occurs quickly and severely, with a high fatality rate.Light cases may show symptoms such as nausea, vomiting, abdominal pain, and diarrhea; severe cases can lead to liver enlargement, jaundice, liver area tenderness, oliguria or anuria, kidney percussion pain, etc. Without timely treatment, it could result in liver and kidney failure leading to death.

The severity of poisoning is generally related to the amount of gallbladder bile consumed; consuming more bile from larger fish increases the risk of poisoning.

2. Eating raw fish slices can lead to "liver fluke disease"Many people enjoy the fresh and tender taste of raw fish slices but are unaware that it harms their liver, easily causing liver fluke infection or even liver cancer.According to experts in nutrition and health, liver fluke disease is a parasitic disease mainly affecting the liver. People can be infected through consuming undercooked or half-cooked freshwater fish and shrimp containing live fluke cysts; millions of people are affected by this disease in Guangdong Province alone.

Common symptoms include fatigue, upper abdominal discomfort, indigestion, abdominal pain, diarrhea, hepatic dullness, jaundice, hepatomegaly, dizziness, etc. In severe cases, it can lead to liver cirrhosis with ascites and even death.

3. Eating freshly killed fish may pose health risks from residual toxinsMany people believe that the fresher the fish, the better, so they prefer to kill and eat immediately for its freshness and nutrition.This is a misconception.Fish in both artificial breeding and wild conditions contain certain toxic substances.Killing fresh-eaten fish means toxins have not fully been expelled, parasites and bacteria are still alive; these residual toxins may harm health.Additionally, the protein has not completely broken down, making nutrients incomplete and taste not optimal.

4. Eating fish on an empty stomach can lead to "gout"

Many people eat only vegetables without rice during weight loss, often eating fish on an empty stomach; this might trigger gout attacks.Gout is a disease caused by abnormal purine metabolism leading to increased blood uric acid levels and tissue damage.Most fish are rich in purines. If large amounts of fish meat high in purines are consumed without enough carbohydrates to break them down, the body's pH balance can be disrupted, potentially triggering gout or worsening existing gout cases.

Those who love fish must avoid these four mistakes to ensure health benefits rather than disease.

Conclusion: Through the analysis of some diseases and how eating fish might harm people in this article, everyone should have a better understanding of how to eat fish and which people can safely consume it. If you also enjoy eating fish, be sure to avoid the above situations to prevent other illnesses from occurring.But this is actually a misconception.Whether it's farmed fish or wild fish, they all contain certain toxic substances in their bodies.Live-killed and eaten immediately, the toxic substances in the fish often do not have enough time to be fully eliminated, and the parasites and bacteria on the fish body are also not completely dead; these residual toxins may harm the body.In addition, the proteins of live-killed and eaten fish have not been fully broken down, the nutritional components are insufficient, and the taste is not the best either.

4. Eating fish on an empty stomach can lead to gout

With today's trend towards weight loss (weight-loss products), many people prefer just eating vegetables without rice or bread; eating fish on an empty stomach is a common occurrence. But this may trigger a gout attack.Gout is a disease caused by metabolic disorders of purines leading to increased blood uric acid and tissue damage.And most fish are rich in purines. If large amounts of fish meat containing purines are consumed on an empty stomach without sufficient carbohydrates for breakdown, the body's pH balance may be disrupted, easily triggering gout or worsening the condition of gout patients.Men who love eating fish should avoid these four mistakes to prevent overcompensation and end up with disease instead.

Conclusion: Through this article, we have analyzed some diseases that can be caused by eating fish.
