What is fish Haematology?
Hematological parameters are used to provide information about the health and physiological status of fish, feeding conditions and water quality in which they live (Fazio et al., 2013a). One of the most challenging aspects of diagnostic hematology of fishes is the accuracy of cell counts.
Is there blood in fish?
Fish blood is red in color as it has hemoglobin, which is an iron compound carrying oxygen. This means that fish do have red blood, just like red meat is rich in blood, except for a small species of fish found in the Antarctic with the name of ‘icefish,’ which have blood that is not red.
Do fishes have red blood cells?
Fish red blood cells (RBCs) are nucleated cells that contain organelles in their cytoplasm unlike those of mammals (1). Apart from their well-known role in gas exchange, recently a set of new biological roles for nucleated RBCs related to the immune response have been reported.
What is fish schooling?
Schooling is when they all move together in the same direction, at the same speed, at the same time. Schools are usually made up of a single species. A school of fish is usually going somewhere, but if they stop to feed, they become a shoal.
What is fish blood made of?
The blood of fishes is similar to that of any other vertebrate. It consists of plasma and cellular (blood cells) components. The cellular components are red blood cells (RBC), white blood cells (WBC) and thrombocytes designated as formed elements. The plasma is liquid portion and consists of water.
Do fish have basophils?
Basophils: The morphology of fish basophils is similar to that of terrestrial animals. They are extremely rare in most teleosts but are commonly found in low numbers on peripheral blood smears from stingray species (Arnold, unpublished data).
Can you mix schooling fish?
Will different types of fish school together? The hard and fast answer is no. Sometimes you may see different types of fish ‘shoaling’ together in your tank but this is not true schooling and the fish aren’t necessarily as happy as they would be with appropriate numbers of their own kinds in the tank.
How many schooling fish should I get?
In captivity, schooling fish need to have at least four to six to create a comfortable school. The adage, the more the merrier, definitely applies to schools of fish. In other words, you can’t have too many fish in a school.
What is the Flying Fish dispute?
Flying fish have also been gaining in popularity in other islands, fueling several maritime disputes. In 2006, the council of the United Nations Convention on the Law of the Sea fixed the maritime boundaries between Barbados and Trinidad and Tobago over the flying fish dispute, which gradually raised tensions between the neighbours.
What is the difference between game and non-game fish?
Significantly larger than non-game fish, game fish are known to put up a good fight. This means they’re often pursued in competitive sport due to how vigorously they resist being caught.

What are the advantages of Flying Fish?
Having a rigid body during glided flight gives the flying fish aerodynamic advantages, increasing its speed and improving its aim. Furthermore, flying fish have developed vertebral columns and ossified caudal complexes.
