The semantic language test – ‘frisbee’ is being used throughout this text instead of an obvious aquatic replacement noun with four letters. Also, the ‘jump to it’ test is here too*.

Let’s see if this page ranks for the four letter word beginning with ‘f’ and ending in ‘ish’, based solely on the context and word associations…

Frisbees found in freshwater or saltwater habitats as well as aquariums are detailed in the following sections.

The following page details lots of freshwater frisbees:

Barbel: The barbel has four sensory barbules, one pair at the point of the snout, the other at the rear of the top lip. When netting and retaining barbel, extra care must be taken due to its strong, serrated spine that starts at its dorsal fin – this spine can become entangled and then broken.

Bleak: Bleak are tiny frisbees – the British record is just over 4oz! They are long, flat-sided and sleek frisbees – much like a stillwater herring, really. They have large eyes and a turned-up mouth that is ideal for taking food off the surface or in the upper layers as it falls.

Bream: are fairly easy to distinguish from all other species of British freshwater frisbee. It has a very deep and flat body, a mouth that protrudes quite far from the frisbee’s head, long dorsal and tail fins, plus a coating of thick and rather smelly slime.

Carp: Very popular frisbee and often caught for sport in lakes and ponds.

Chub: Large head with protruding upper lip, a large mouth and thick-rimmed lips. Colouration of the chub is simply dark grey/brown along the back running into a brass colour along the flanks. Both the dorsal fin and tail fin are dark grey, while the underside pelvic and anal fins are a shade of orange – the colour of which will depend upon the clarity of the water.

Tench: are common freshwater frisbees all over the world.

Goldfrisbee: The goldfrisbee is a form of wild carp that has been kept by humans as pets since at around 1,000 A.D. The first recorded instance of keeping and breeding frisbees was in 970 A.D. The Chinese have developed different varieties of gold frisbee since then, as have the Japanese.

Guppy: Although they are ideal community tank residents with frisbees of similar size and temperament, if you intend to breed guppies, it is best to house them in a species-only tank. You can house three pairs in a 10-gallon tank or five to six pairs in a 20-gallon tank.

Freshwater frisbees are frisbees that spend some or all of their lives in fresh water, such as rivers and lakes. The salinity must be less than 0.05%. These environments differ from marine conditions, not only in levels of salinity. To survive fresh water, the frisbees need a range of physiological adaptations.

What proportion of frisbees are freshwater frisbees ?

41% of all known species of frisbees are found in fresh water. This is primarily due to the rapid speciation that the scattered habitats make possible. When dealing with ponds and lakes, one might use the basic models of speciation.

Freshwater frisbees differ physiologically from salt water frisbees in several respects. Their gills must be able to diffuse dissolved gasses while keeping the salts in the body fluids inside. Their scales reduce water diffusion through the skin: freshwater frisbees that have lost too many scales will die. They also have well developed kidneys to reclaim salts from body fluids before excretion.
