Fins … From here it drains through the bile duct into the intestine, where it is mixed with the solid waste. I also think she might have a little red on her left pectoral fin. The red blood cells contain haemoglobin, a red pigment that binds with oxygen. Fish swim using the body muscle, and the fins play an important role in maintaining stability in the water. The position of the eyes on the head gives them almost total 360⁰ vision, enabling them to see above and behind, as well as in front and below themselves. This layer of mucus is continually being refreshed as the old mucus sloughs off into the water. The ovaries are relatively large and irregularly shaped organs in mature female Koi.

Indeed, in embryo Koi the swimbladder develops as a minute outgrowth from the gut. Standard fin Koi have pectoral fins which are proportional to their bodies and usually short and round to oval in shape. If a cone is placed with the pointed end turned into a current of water, the water swirls at the rear flattened surface, creating turbulence, or drag. The thin epithelial layer lining the filamentous gill structures is very thin and allows gas exchange to occur here. Under the epidermis is the dermis and this is where the scales are formed. Koi Fish and Injections of Antibiotics. Insert the needle at an angle, aiming through the fish as if to emerge at the mouth, going in just behind the ventral fins, but well in front of the anus or vent. Salts move by diffusion in the opposite direction. The epidermis is responsible for mucus production and assists wound repair by multiplying to cover areas of damage. The second chamber, or atrium, is also thin walled, but expandable. All accumulate in injured, inflamed or infected areas of the body, where they repel bacterial or viral invasions, remove dead or damaged tissue, and assist in repairing damaged tissues. The speed of reaction also depends upon the water temperature; lower temperatures lengthen the response time of the immune system, while levels of pathogen activity may still be high. The pectoral and pelvic fins also control fine movement by counteracting the propulsive forward motion caused by the exhalation of water from the gill covers, thus enabling the Koi to remain motionless. The heart provides the pumping force to move the blood through these vessels, first to the gills and then to the brain and the remaining parts of the body, before returning once again to the heart. Pectoral fins are for locomotion and side to side movement Adipose fins - The Adipose fin is an extra fleshy fin on the back behind the dorsal fin … The pectoral fins … First recorded activity by GardenBanter: Aug 2007, Yesterday I noticed 1 of my 3 Butterfly Koi has a sizeable split in, First recorded activity by GardenBanter: Dec 2006, Our butterfly koi have also expereinced splits.

There are two distinct types of scale pattern found on Koi: completely scaled, and the so-called doitsu, in which the scales are enlarged and arranged along the midline of each side of the body and, usually at the dorsal and anal fin bases. The autonomic nervous system controls the unconscious activity of organs such as the gut, gills and certain glands. 1° & 2° lamellae on each gill arch There are three … The liver in Koi is very large and consists of several lobes. As in other vertebrate animals, its main role is to act as a through route for nervous impulses traveling between the body and the brain.

The gut performs three major functions: physical breakdown and mixing of food (by the teeth); chemical breakdown (by digestive enzymes); and absorption of the food materials. A koi's skin is covered by a layer of mucus, which not only offers protection against disease but also helps streamline the fish to aid locomotion. Some of these nitrogen products, together with any excess water, are transported in the blood to the kidneys, where they are extracted and processed into urine. Along the middle of each side of the body there is a row of scales, each pierced by a small pore that connects by way of a small tube to a canal that lies in the skin beneath the scales. Many experts think that they actually see things in a very similar way to humans, and are able to make out shapes and colors. The tubules are connected to a system of ducts that merge into a single one, the ureter, which runs from the kidneys to a pore just in front of the vent, where the urine is voided. The ability to see above and behind is particularly important because it enables Koi to watch for the approach of enemies while they are feeding. The internal anatomy is more complex than the external anatomy, not only because of the number of different organs involved, but also the way these various organs interact. Once the nutritive content of the food has been absorbed into the bloodstream, the remaining solid, undigestible material is voided. Many of our higher end koi are individually photographed, numbered, and priced, so if you can … Below the mucus lies the top layer of skin know as the epidermis. This connecting duct enables Koi to top up the swimbladder by gulping and swallowing air at the water surface. Just in front of the vent there is a smaller opening which receives the urinary ducts form the kidneys. Koi not included in the fifteen varieties mentioned so far are grouped as "Kawarimono."

The spleen is responsible for the production of cells that are vital to the fish's immune system, and it also acts as a store for immature red blood cells. The surface of the filaments is highly folded, enormously increasing their surface area, and the skin is extremely thin, allowing intimate contact between the blood and water. The pancreas is a soft tissue, similar in appearance to the liver, that produces a number of digestive enzymes, which it releases into the intestine to chemically break down food.
