Abstract
Kafr El-sheikh governorate is considered to be the first in fish
production among all governorates in Egypt. it produces about 145.5
thousand ton or about 18.9% of the total fish production in Egypt in
2002/2003. Thus the main target of this study is to investigate factors
affecting fish production in El-zawia fish farm, Kafr El-sheikh governorate.
Series data as across sectional data for 54 observations during the
period mentioned above were used and analyzed by multiple linear
regression model, non-linear form as wall as the stepwise analysis.
The fish varieties have been studied in the farm are: (i) Mullet and
Ramada, (2) Tilapia. (3) Carp < /p>
The most important results in according to economic statistical
analysis of the linear and logarithmical functions are as the fallowing. The
most important effective factors an fishery production are:
Firstly: Mullet species:
The important effective factors on the mullet and Ramada altogether
are: The number Mullet-Ramada fingerling the number of the workers affects
on the output of Mullet Ramada in the second yield stage. The production
elasticities are about 0.04%, 0.06% respectively. But the output of tilapia
affects inversely on the output of mullet Ramada altogether. The substitution
elasticity is about 3.3%. _ ' ‘ ‘
Secondly: Tilapia species: _ g ‘ __ .
The amount of forage affects an the production of tilapia in the second
yield stage. The production elasticity is about 0.21% but the tilapia output
affects on the output of mullet and Ramada in the same .direction. The
substitution elasticity is about 0.85%.
Thirdly: Carp species:
_ fl The output of mullet—Ramada affects of the output of carp fish in the
same direction. The“ marginal rate of substitution isqabout 020 ton. The
results show that there is integration economic- statistical relation ship < /p>
between them.
