What are the uses of fishes to human?
1) Humans love to eat fish! Fish also is a brain food and enhances your thinking abilities. I swear by this and even made sure to eat fish before taking exams in college and I always aced my tests and still have a 4.00 GPA! Fish oil is very good for the heart and the brain too.
2) Fish are great for our sporting pleasure. There is something to be said for the relaxation and feelings of accomplishment when we catch fish!
3) Pet fish are beautiful and stress relieving when they are living in an aquarium and educational when it comes to watching their behaviors.
4) I would imagine they are great for our waters because they eat the unwanted insects or plants, or etc! I am not really sure on this one!
5) Fish oils are great for your skin and hair as well!
What kind of fish have pink meat?
The Blue Ling Cod has blue meat!!

I believe they are called Sculpin, and I think the ones my dad and I used to catch in Alaska was called "bullhead" or "staghorn" sculpin.
What does it mean if you dream you caught a big fish?
No one else can tell you what your dreams mean. Only you know your own personal symbolism. Dream dictionaries are a load of hokum.
Ask yourself these questions:
1. How did the elements of the dream make me feel?
2. What was the general theme of the dream?
3. How do I feel about fish?
4. How do I feel about people throwing up?
It could mean absolutely anything. Perhaps you watched a film in which someone got food poisoning from eating fish, perhaps you overheard a conversation in which someone discussed their dislike of whales. It might have no significance at all, or you might think of fish in a deeply symbolic way. A fish to a Christian can be much more symbolically significant than it would be to, say, an atheist.
Water is not considered a food. It is necessary for proper bodily functions, but it does not nourish you with vital nutrients like proteins, fats, or carbohydrates that provide calories for the energy our bodies need. Therefore, it is not listed among the nutritional food groups.
Conus, which is a predatory sea snail is venomous and capable of stinging humans. It uses a radula tooth and a venom gland to attack and paralyze their prey before eating it.
The giant marine sunfish has been kept in captivity for around 10 years or so. There is no reliable information that I can find on their lifespan in the wild. They do get very big though and grow to well over 1 ton in weight.
What came before the fish amphibians reptiles and dinosaurs?
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
he might have a diaese and if you feed him pelleted food stop and give him flaked food
Keralas have long fish heads, with sizes I have seen ranging from 5 to 10 cm.
Apart from the fact that they are both fish there is no relationship whatsoever.
What does egg do in fish cakes?
It holds the flakes of fish together, and any other dry materials such as potato.
To swim..? If you mean the fin on top of their bodies then it helps stabilize them.
How many people like to eat fish?
no one acctually knows how many people because there are to many people and not enough spys. the answer is: No one knows!!
How does a fish swim in a water?
I believe most fish can swim. There is always something that differs from the normal like a Starfish and there must be other sea creatures called fish that don't swim, but yes, in general, a fish can swim.

How many eggs do the average angler fish lay?
Not all tropical fish even lay eggs, guppies, platys, and swordtails are good example of livebearer tropical fish. So the number of eggs a tropical fish lays cannot be determined.
Why aren't we seeing a lot of marine life in certain parts of the Gulf of Mexico? You don't have to be a doctor to answer this question, but you do have to have some scientific tools to diagnose the problem.
On the Oregon II, a device called a CTD is used to take measurements such as conductivity (salinity), temperature, chlorophyll concentration, and dissolved oxygen (DO). These water quality measurements let researches know what's happening in the water just like a doctor would look at your test results to gage your health status. Sometimes a doctor may need to do a second test just to confirm the results. NOAA's fisheries biologists do the same thing with their water quality assessments. Winkler titrations and a hand-held Hack Dissolved Oxygen meter are used to confirm the dissolved oxygen readings from the CTD. Scientists need to make sure the data they collect is accurate and the more tests they perform the better their data will be.
This large piece of equipment is a CTD sensor. The top portion of the machine contains three gray vertical cylinders which are used to collect water samples. Under the machine are sensors that test the water quality while it is submerged. Here I am washing out the sensors once it was brought back on board from a test.
When comparing data from this device to our trawl samples, it's obvious that water with low levels of dissolved oxygen can not support much life.
Dissolved Oxygen: Marine animals need oxygen to survive just like land animals do. The main difference is that most marine animals have gills which are able to diffuse oxygen molecules from the water directly into their blood. Diffusion is the process of a molecule moving from an area of high concentration to low concentration.
Have you ever sprayed air freshener and noticed how the smell moves from where you sprayed it (high concentration) throughout the entire room (low concentration) until the smell is equally distributed throughout the room (equilibrium)? That's how diffusion works.
It's very important to understand that the amount of dissolved oxygen MUST be higher in the water then inside of the animal's body or diffusion of oxygen into the blood won't take place. This means the animals will either have to move or die. This is what's happening in the "Dead Zone" in the Gulf of Mexico.
The reason levels of oxygen are so low in the Gulf of Mexico are due in part to human actions. The overuse of fertilizers that are high in nitrates and phosphates are one of the major problems. When it rains or floods, these extra nutrients wash off of our lawns and into storm drains which then drain into the rivers. Most of the Mississippi watershed consists of agricultural land in the breadbasket of the Midwest where a lot of fertilization takes place during the spring and summer months. All of the nutrients from the rivers in the Mississippi watershed eventually empty out into the Gulf of Mexico.
What bony items cover a bony fish's skin?
Bones are made of calcium. This is the same for all bones found in mammals, birds, reptiles, amphibians and fish. The 'softer tissue structures' found in other fishes is cartilage. These are the rays, sharks and the like.
What type of fish are there in Egypt?
there were no fish in Egypt cause its 2 dry 4 a fish 2 be there
Bony fish have adapted many different ways to eat food. Some are filter feeders like the anchovies. Tuna are predators that seek out weak or injured prey. Catfish are bottom feeders using the whiskers to find food and the molars to grind it up. The wolf eel is known for its fearsome teeth used to hold its prey.
Starfish commonly reproduce via a method called "free-spawning". This means that they release their gametes (A reproductive cell that has a haploid number of chromosomes, normally a mature sperm or egg that is capable of fusing with a gamete of the opposite gender to create a fertilized egg) into the water, where they will hopefully be fertilized by the gamete from the opposite sex. It is thought that to increase the chances of fertilization, starfish will gather in groups when they are ready to spawn, using environmental signals to coordinate their timing, and chemical signals to indicate their readiness to each sperm.
