The reported output from global aquaculture operations would supply one half of the fish and shellfish that is directly consumed by humans ; however, there are issues about the reliability of the reported figures.

This may appear counterintuitive ; however, the bodies of fish are shaped to produce very low resistance as they travel through water.

These fish can still, however, find their way around by means of their lateral lines, which are highly sensitive to fluctuating water pressure.

Astyanax jordani, however, is another blind cave fish, independently and recently evolved from the sighted surface form, which is sometimes confused with the cave form of A. mexicanus.

The Byzantine cuisine was similar to the classical cuisine including however new ingredients that were not available before, like caviar, nutmeg and lemons, with fish continuing to be an integral part of the diet.

At the beginning of the Imperial era, however, this custom suddenly came to an end, which is why mullus in the feast of Trimalchio ( see the Satyricon ) could be shown as a characteristic of the parvenu, who bores his guests with an unfashionable display of dying fish.

Freshwater is more dilute than the internal fluids of fish, however, so freshwater fish gain water osmotically through their gills.

It is virtually impossible to define a particular color pattern as belonging to a specific breed ; however, in general, wild fish are claimed to have more vivid colors and patterns.

Most, however, are small shoaling fish.

The term " livestock " as used in this article does not include poultry or farmed fish ; however the inclusion of these, especially poultry, within the meaning of " livestock " is common.

As non-mammalian animals that spend their entire lives in water they are " fish " in the logical sense ; however the denotion finfish ( or finnicle fish ) has been developed to distinguish fish as animals defined by having vertebrae from shellfish in modern terminology.

The fishermen, however, want the remaining water in the lake to stay so they can continue to fish and not have to worry about the lake shrinking more and decreasing their already strained supply of fish.

Each of these lineages, however, remains grouped with the tetrapoda, just as Homo sapiens could be considered a very highly specialized kind of lobe-finned fish.

Animal flesh decays considerably faster, however, so the fertility of the lake is dependent on the rate at which these nutrients can be taken up by fish and other organisms.

The removal of Haplochromis, however, may have contributed to the increasing frequency of algal blooms, which may in turn be responsible for mass fish kills.

This backfired, however, because it generated more publicity — newspapers across the world ran stories about the miraculous fish.

Its long-term strategy, however, is illustrated by the analogy of the three Siamese fighting fish Blofeld keeps in an aquarium in the film version of From Russia with Love.

The largest biomass of fish, however, is in the pelagic zone ( open waters ) and is dominated by six species: two species of " Tanganyika sardine " and four species of predatory lates ( related to, but not the same as, the Nile perch that has devastated Lake Victoria cichlids ).

Unlike bony fish, there is no direct control of the pigment cells by the nervous system, and this results in the colour change taking place more slowly than happens in fish.

Aquatic invertebrates and fish might then die and there would be unpredictable ecological consequences.

The Chief Joseph Dam and several dams on the Columbia's tributaries entirely block migration, and there are no migrating fish on the river above these dams.

Wildlife diversity is very high ; there are 441 species of amphibians and reptiles, 838 species of birds, 232 species of mammals and 181 species of fresh water fish.

In 1778 the French Governor of Mauritius granted Monsieur Dupuit de la Faye the island of Diego Garcia, and there is evidence of temporary French visits to collect coconuts and fish.

Eritrea exports fish and sea cucumbers from the Red Sea to markets in Europe and Asia, and there is hope that the construction of a new, jet-capable airport in Massawa, as well as rehabilitation of the port there, may support increased exports of high-value seafood.

Until fairly recent times, there has been a remarkable homogeneity in the culture throughout this area, which traditionally relied on fish, sea mammals, and land animals for food, heat, light, clothing and tools.

Clement of Alexandria, in his Paedagogus ( The Pedagogue ) 3. 59. 2-3. 60, writes that Christians may wear a seal ring for the sealing of documents, and he specifies permissible depictions: " And let our seals be either a dove, or a fish, or a ship scudding before the wind, or a musical lyre, which Polycrates used, or a ship's anchor, which Seleucus got engraved as a device ; and if there be one fishing, he will remember the apostle, and the children drawn out of the water.

However, the situation is not always so simple ; in cartilaginous fish and some amphibians, there is also a shorter duct, similar to the amniote ureter, which drains the posterior ( metanephric ) parts of the kidney, and joins with the archinephric duct at the bladder or cloaca.

Since there are no inflows that link the lake to other large waterways and the main outflow, the Blue Nile, is obstructed by the Blue Nile Falls, the lake supports a highly distinctive fish fauna, which generally is related to species from the Nile Basin.

The fossil fish there soon attracted his attention.

In modern Italian there are three words corresponding to the English word ' soup ': zuppa, which is used in the sense of tomato soup, or fish soup ; minestra, which is used in the sense of a more substantial soup such as a vegetable soup, and also for ' dry ' soups, namely pasta dishes ; and minestrone, which means a very substantial or large soup or stew, though the meaning has now come to be associated with this particular dish.

Most bony fish belong to the ray-finned fish ( Actinopterygii ); there are only eight living species of non-tetrapod lobe-finned fish ( Sarcopterygii ), including the lungfish and coelacanths.

However, many species produce a far greater number of eggs during their lifetime than do humans, so that, in fish and amphibians, there may be hundreds, or even millions of fertile eggs present in the ovary at any given time.

In the primitive jawless fish, and some teleosts, there is only one ovary, formed by the fusion of the paired organs in the embryo.

* Uncontrolled deforestation in watershed areas ; soil erosion ; air and water pollution in Manila ; increasing pollution of coastal mangrove swamps which are important fish breeding grounds ; severe water pollution that caused the death of one of the country's major rivers, though there are ongoing efforts at resuscitation.

They are often cheaper than other fish, and because they contain inconsistent levels of toxins between fish and season, there is little awareness or monitoring of the danger.

The most popular pets are dogs and cats, but there are also rodent pets, such as gerbils, hamsters, chinchillas, fancy rats, and guinea pigs ; avian pets, such as canaries, parakeets, and parrots ; reptile pets, such as turtles, lizards and snakes ; and aquatic pets, such as tropical fish and frogs.

The fish, animals, and birds which may be found at the site are another interest.

Fishing interest calls for a check of the species found, quantity and size, the season they are available, and the stocking program of the fish commission.

their classes of animal and plant terms are restricted to generalizations or recurrent parts ( fish, bird, tree, grass, horn, tail, bark, root ).

Reefs are left high and dry, and the beaches are covered with stranded fish.

In the juvenile ( or tadpole ) stage, gills are used to oxygenate blood and the circulation is similar to that of fish.

Some species are carnivorous at the tadpole stage, eating insects, smaller tadpoles and fish.

The major fish are cod, haddock, hake, herring, and mackerel.

These fish are not found in caves north of the White River.

Freshwater fish such as bream, shad, bass, and sucker are common.

Further, in current aquaculture practice, products from several pounds of wild fish are used to produce one pound of a piscivorous fish like salmon.

Diatom production continues through the summer, and populations of krill are sustained, bringing large numbers of cetaceans, cephalopods, seals, birds and fish to the area < sup ></ sup >.

They become semi-aggressive as they age, but are by nature schooling fish, and a group of at least three is a good idea.

Healthy populations of many sorts of fish are found in the waters ( including salmonids such as several species of salmon, trout, char, and so on .).

They are an important food for many birds and fish, and are cultured and harvested for use as fish food.
