Abstract

Fish production from natural fisheries in El-Fayoum Governorate at is
characterized by a fisheries of Qarun lake, Wadi El-Rayan lakes and Bahr
Youssef and its canals, like other Egyptian natural fisheries seasonal
fluctuations severe.
Science the enter product of fish catch which represents about 40% of
total fish catch from El-Fayoum Governorate fisheries which phrase about
22.4 thousand tons in 2012 despite the fact that water area represents more
than 90% of the total fish water resources preservation area estimated at about
100 thousand feddan during the same year , as well as the diversity of
environment and water to those of natural fisheries to maintain between saline
, brackish and fresh which means diverse fish species trap them between
marine species such as Solia and Mullet , and varieties of fresh water such as
Tilapia and catfish varieties brackish water mostly fresh water fish , followed
by the diversity of the trap varieties of those fisheries the different in breeding
seasons dates and lay eggs each.
This research is aims to study seasonality of fish production from those
fisheries to keep those items specially during periods of breeding and laying
eggs in order to increase the annual fish catch from them The study based on
the use of averages, percentages and seasonal guide to calculate the
seasonality of fish production from these natural fisheries during the period
2008-2012.
Among the most important research findings of the study that the
seasonal fluctuations of fish production from Wadi El-Rayan lakes is the most
sever and the inter intensity by a factor of seasonal estimated at about 51.2,
while this factor in karon lake at about 4.8 which means high severity but far
less than from those Wadi El-Rayan lakes And virtually no such seasonal
fluctuations of fish productions Bahr Youssef and its canals by a factor of as
much as about 1.2 only.
Decision – makers in El-Fayoum governorate can organize the Fish
supply which caught from the natural fishery throughout the months of the
year by identifying the lowest and the highest fish production months. Fish
culture can preservation contribute to the organization that fish supply
throughout the private and the resulting fish than a year it contributes about
60% of total fish catch in El-Fayoum Governorate in 2012 , which would
maintain the moderate prices of fish in fish markets throughout the year in ElFayoum Governorate.
