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.
What does it mean to dream about frozen fish?
im a fortune teller and it means that you will be a fishmonger when your older, if your old now then in your next life you will be a fish on the fishmonger
Is the brown trout an endangered species?
No..The steelhead is a rainbow trout that spends most of its adult life in the sea.
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.
You can buy sea monkey food in Wal-Mart or on ebay.com.
Thanks for Reading :+)
What is the classes for bony fish?
If you are doing the cross word, the answer is Sturgeon - one of the oldest bony fish linking to fossils of primitive type. ;-)
Does a lion fish interact with other fish?
Natural predators in the Indo-Pacific and Red Sea that are known to eat lionfish include sharks, cornetfish, grouper, large eels, frogfish and other scorpionfish. There is speculation that large snapperand some species of trigger fish eat lionfish in their native ranges as well
What do carp fish look like What do cap fish eat?
Carp eat alligators but small one babies shall i say
How warm should a fish tank be before putting fish in it?
With the gravel, and the filter, and your ornaments/plants ready in it, you need to leave it for 1-2 weeks. (depending how desperate you are) You should not buy your fish unless you have had it ready for 1-2 weeks!
What is the main source of food of angler fish?
The main food of the anglerfish is anything it can get to eat on the ocean floor because its a carnivore.
What are adaptations for flying fish?
they can easily adapt to any freshwater places because it eats all types of foods
Perch eat the same way that other fish do. They open their mouths, suck in the food and eat it. They eat a variety of things in the water.
Where are the nostrils located on a perch?
above the mouth; there are two of them although the nostrils differ slightly from those of humans
Can you cook fish that is only partially defrosted?
I am a chef and I think I know how to answer this. YES! Yes you can cook defrosted food. Just as long as you defrost it ALL THE WAY. You don't want to start cooking something (like chicken) that is partly frozen. Even just a little bit frozen.
What fish eat purple sea urchin?
There are several animals that eat sea urchins. Sea otters, sunflower stars, snails, crabs and some species of fish predate upon sea urchins.
How do you tell if my betta fish is suffering?
Well betta fish cannot be in tap water. It's like poison to them. They have to have treated water. I found out my betta was suffering when he wouldn't eat anything. Betta like to be out in the open so they can see movement and action. The living room is a good place.
Your goldfish won't move and it won't go to the surface to eat?
If you can see that the fishes gills are still opening and closing, the fish is still breathing. The most important thing is to change its water ASAP. It may still die if you do change its water from the damage done to its gills by ammonia. The commonest thing that kills fish in captivity is the Ammonia in the water that is produced by the fish living and breathing in the water. That is why fish keepers have a basic set of minimum conditions. They are :- 1 inch of fish needs a minimum of 1 gallon of water, a cycled filter to remove the ammonia produced by aquatic life, and a minimum of 50% water changed weekly to remove the nitrate produced in the filter.
In a lake, in rivers, stream, and in the ocean. The best salmon are caught in the Pacific Northwest, especially in Alaska.
Why is your fish sleeping all the time?
Well, for one thing, it might be dead, but probably not. Your chicken could have a disease that is making it lethargic, therefore take it to the vet.
Or, your chicken could just be overly tired, in that case try giving it some sugar water. It may be lacking some protien, so you should give it some boiled egg.
