Do brook groupers eat black shell shrimp, what do brook groupers eat

Creek grouper eats black-shelled shrimp.

The brook grouper itself is not poisonous, but its eggs are poisonous, and brook grouper is a freshwater grouper.

Its eggs gradually become poisonous during the developmental stage, with mature eggs being the most toxic, but the flesh is non-toxic and edible.

Creek grouper eggs are toxic mainly because their eggs contain a colorless and odorless neurotoxin.

Ciguatoxin", which does not affect the fish itself, but can cause poisoning when consumed by humans, poultry or livestock.

After eating poisoning with eggs, the reaction generally occurs within 2-10 hours, and the main symptom is dizziness.

Fatigue, nausea, vomiting, abdominal cramps, diarrhea, numbness in the limbs, knee soreness, tingling in the calf muscles, itching, cold sweats, dizziness.

Chest tightness, etc., severe cases of spasms, convulsions, coma, rapid development of the disease can lead to death.

Tips and tricks for fishing for brook grouper.

1. Time. Brook groupers are active in foraging and are more active, and fishing options are more suitable from early March to late October.

2. Bait. If you want the brook grouper to be easy to bait, it is recommended to choose a bait similar to breadworm in the choice of bait.

Earthworms and the like, this is a favorite food for groupers.

3. Location. Brook groupers like to forage in the rapids of small streams such as rocks and rock pools, so it is best to fish in a location with these characteristics.

4. a buoy. If you use a buoy to fish for grouper, you should immediately lift the rod if you find that the buoy is sinking, because the grouper has a fierce temperament, and when it finds food, it will be caught quickly and the action is faster, so the buoy will sink quickly, and this situation is generally hooked.

<> brook grouper eats plankton.

insect larvae, etc. In the larval period, this fish is mainly zooplankton, and can be fed rotifers and daphnia.

When the land is gone, if it grows to more than 1 cm, you can feed soy milk. When it grows to 2 cm long, its feeding habits begin to change, and earthworms need to be fed.

Maggots and surimi were then fed with artificial feed, and gradually changed to feed Zaolina with artificial feed.

Groupers are apex predators of coral reef ecosystems and are overwhelmingly carnivorous, feeding mainly on other fish, crustaceans and cephalopods.

However, there are also some filter-feeding groupers, such as the paraflora (paranthiasspp.).They have dense gill rakers that filter water from plankton such as copepods, tunicates, amphipods, and larvae of fish and gastropods.

The hunting strategy of groupers also varies from species to species: some of the main species of predator, such as the gill perch (Plectropomus) and the genus Variola, will usually cruise around reefs or shoals in search of prey.

Other species such as the Caribbean perch (C. alba)Cruentata), Leopard Bass (CLeopardus) and others are good at hiding in corals and reefs, ambushing passing fish and crustaceans.

The typical grouper has a large mouth and a large head, which allows them to inhale a large amount of water in a very short period of time to create negative pressure and suck their prey into their mouths, which have numerous small inward tines to prevent the prey from escaping from their mouths.

Some groupers have also been recorded to cooperate with nudibranchs or other fish, such as the wormgill perch and leopard gill perch have been observed to cooperate with Javan bare-breasted and corrugated lipfish, and the grouper guides its collaborators to participate in the predation through body swings and "nodding".

Freshwater groupers feed on plankton and insects attached to the rock walls. Freshwater grouper is inward.

Carnivorous fish, fry stage, carnivorous characteristics.

Freshwater grouper is a tropical fish that grows in freshwater and can also grow in seawater with a salinity of less than 10. Its suitable temperature range is between 25-30, when the water temperature drops to 20, the feeding is significantly reduced, and the body is out of balance when the water temperature drops to 15, so the area where the pond water will drop below 15 during winter is not suitable for freshwater grouper growth. During the wintering period, freshwater groupers grow at temperatures above 19.
