Value chain analysis of Egyptian fish seed production
Type: Conference Paper
The current study is designed to provide more information on one of the main inputs for the Egyptian aquaculture value chains, i.e., the supply of fish seed. The study focused on the four selected governorates, namely ...
Biological control of the cyanobacterium Microcystis aeruginosa using Chlorella and Scenedesmus mass culture
Type: Conference Paper
This study aimed to investigate the use of Chlorophyta Chlorella elliposoides and Scenedesmus bijuga (Turpin) Lageh as a biological control means against Microcystis aeruginosa Kutz as a laboratory trial before field application.
Effect of some local immunostimulants on the survival, growth performance and challenge infection of Oreochromis niloticus
Type: Conference Paper
Disease outbreaks are encountered in the rapidly developing aquaculture industry and affecting the economy but their controls seem to be difficult. Therefore, the use of immunostimulants may be an effective mean of increasing ...
Pathological studies on encysted metacercariae infections among some freshwater fish in Egyptian aquaculture
Type: Conference Paper
Fish may harbor pathogens especially parasitic diseases which interfere with the aquaculture production and could consitiute a zoonotic importance, especially in developing countries. In this study, 200 freshwater fishes ...
Value chain analysis of the Egyptian aquaculture sector
Type: Conference Paper
Egypt’s aquaculture production (921,585 tonnes in 2010) is by far the largest of any African country and places it 11th in terms of global production. Despite the fact that the aquaculture sector in Egypt is now a mature ...
Aquaculture genetics research in Egypt
Type: Conference Paper
Fish production in Egypt has significantly increased over the last few years reaching 546 000 t in 1998 compared to 306 000 t in 1988. The contribution of aquaculture in the overall fish production has increased as well ...
Laboratory studies for preventing the growth of Microcystis sp. using Chlorella and Sendessmus in the Nile tilapia culture
Type: Conference Paper
This study is a trial for the prevention of Microcystis sp. growth using Chlorella and Scenedesmus mass culture via indoor experiment.
Spatial and Temporal Variation of Length-Weight Parameters and Condition Factors of Commercial Fish Species in Lake Nasser, Egypt
Type: Conference Paper
Length and weight data of fish populations are necessary in stock assessment models and ecosystem modelling. Also, they could be used to spatially compare between different fish populations under different environmental ...
Effect of female weight on reproductive performance of nile tilapia (Oreochromis niloticus)
Type: Conference Paper
The present study aimed to investigate the effect of broodstock size on the reproductive performance of Nile tilapia and to see whether this identifies possible broodstock management strategies that may be adopted by ...
Enhancing fish farm productivity through improved management. A case study in Egypt
Type: Conference Paper
During a 3-week training program held during 1999 on field application for fish culture technology in Egypt, it was noticed that a significant enhancement in pond productivity could be achieved mainly through improved pond ...
