Abstract
Fish including finfish and shellfish are an important source a healthy
food and is a major player in human nutrition, ensuing about 20% of
protein intake to a third of the world’s population which is more evident in
developing countries. It is a central constituent of well-balanced diet,
offering low cholesterol level, high-quality proteins, omega-3 fatty acids,
healthy source of energy, vitamins and other important nutrients.
In Egypt, the need for increasing fish production is necessary in view
of the high demand for fish as a relatively cheap source of animal protein.
For a long time production of fish has been left to “The Mother Nature”,
man harvesting from a natural crop. The transition from hunting fish to
producing fish has come with the construction of fish ponds.
The thin-lipped grey mullet Liza ramada ((Mugiliformes; Mugilidae),
is euryhaline teleost that lives in environments of different salinities:
coastal waters (seawater), estuaries (brackish water), and lagoons
(hypersaline). The grey mullet (Liza ramada) is an important and attractive
species for farming in sea, brackish and fresh water. Its notable
characteristics include a flesh that is highly regarded, and, therefore,
achieves higher market prices with respect to other fish species.
Mullet fish (Mugil cephalus; Liza ramada) are considered as
economic fish for farming in Egypt because of their high nutritional value,
as well as, their ability to cultivate in different salinities. The culture of
mullet depends on the collection of fry from nature, which leads to damage
of nature and competition on those fry, which leads to higher prices. There
is no alternative to this without the establishment of fish hatcheries to
obtain the fry of those fish.
