Collection and distribution of captured mullet fry in Egypt – Video

Review: Abdel Rahman El Gamal (Founder of the video channel)

 

Egypt continues to be the world leader in mullet aquaculture, producing over 157,000 tons in 2015 whereas the culture of mullet relies solely on the collection of wild seed.

The collection of wild fry in Egypt in designated sites is controlled by the General Authority for Fish Resources Development (GAFARD) and carried out by private fishermen under the direct supervision of GAFRD after the permission of coastal guard. Licensed fishermen provide the fishing gears and all collecting and handling equipment as well as the fry reservoir boat shown in the video. Officially, fishermen receive a share of the sale price of the collected fry while the other share is kept for covering the running cost and maintenance of the collecting stations. One may notice that the boat reservoir of mullet fry is directly connected with the sea through screened windows.

The price of collected is determined by GAFRD and announced by an official decree. Collected fry are either sold directly to licensed fish farms according to official quota established by GAFRD, while part of the catch is used for the stock enhancement of specific Egyptian lakes. Another part of collected fry are transported to state nurseries where they are sold as fingerlings afterwards.

Among the collecting stations there are two stations which are specialized in the collection of keeled mullet (Liza carinata) as this species is more tolerant to high salinity which occurs in the Red Sea system. The one shown in this video is in Suez. Regardless the lower growth rate and the smaller size of keeled mullet, the species enjoys premium market price and higher demand compared to the key mullet species especially when processed as salted fish. In a quick shot, one can see the trucks of fish farms waiting to receive their quotas of mullet fry.

It may worth noting that the collection of wild seed is expected to continue to form the basis of mullet culture in Egypt as long as the hatchery-produced mullet fry is not developed at commercial scale to provide the demanded fry at comparable prices to the wild ones.

Review: Lucka Paschal – Erick Kiiza (Tanzania) and Abdel Rahman El Gamal (Founder of the website)

 

 

The inserted picture was taken in Mwamapuli Aquaculture Development Centre which is a governmental center located in Tabora Region at Lgunga District. The picture shows the harvesting of African catfish Clarias gariepinus being the main species produced at the center.

The target of this activity is to distribute the catfish fingerlings to rice farmers in the community for the purpose of integrating fish in rice fields.

Unique modes of fish reproduction: Male seahorse is the parent that gives birth

Review: Samart Detsathit and Abdel Rahman El Gamal (Founder of the website)

 

Seahorses (Hippocampus sp.) are unique aquatic animals whether in regard to their shape or their biological features especially they belong to live bearers. The male seahorse has a breeding pouch in which the female parent deposits her eggs upon the mating. The male fertilizes the eggs and incubates them in the breeding pouch until hatching. During incubation, the seahorse embryos depend on the egg yolk although it is believed that the male parent may provide the embryos with some nutrients especially those are needed for its proper development. The specimen shown in the inserted picture is just born in a hatchery in Thailand.

Development of marine aquaculture in Gaza Strip (Palestine)

Review: Masoud Keshta and Abdel Rahman El Gamal (Founder of the website)

 

 

 

Marine aquaculture in Gaza Strip began to exist in 2008 whereas 8 tons of fish were produced from two farms. Afterwards, steadily developments along with increased production reaching about 700 tons of gilthead seabream and European seabass produced by three farms at the moment. The inserted picture has been taken in the largest farm the took place At present, there are three farms producing about 700 tons; out of which 500 tons are produced in the farm shown in the inserted picture.

This particular farm is located in Rafah Governorate, Gaza Strip. Originally, the farm was established in 2007 to produce tilapia with a production of about ten tons/year.

After two years of tilapia production, a major change in the farm direction took place and the gilthead seabream (Sparus aurata) and the European seabass (Dicentrachus labrax) have been the target species. This particular farm receives its water from wells located close to the sea. The imported fingerlings are grown in metal tanks covered with plastic sheets.

The current fish production of this particular farm is about 500 tons/year; out of which about 40 tons of seabass while the seabream harvest amounted 460 tons. Harvested fish has been locally marketed in Gaza before expanding the marketing chain to include hotels and restaurants especially those which have been established near, turning the area into a touristic place. The current plan of the farm is to increase its production to enable the marketing of the fish in the West Bank as well as in Jordan whenever feasible.

The establishment of a marine hatchery has been planned to provide the required fingerlings for the marine farms whether land-based farms or cages.

Fish hatchery management (2017 – updated)

This lecture on fish hatchery started with general information related to the modes of reproduction in various groups of aquatic organisms as illustrated by pictures and tables highlighting the significant differences of reproduction among various fish groups ranging from scattering eggs to giving birth passing by fecundity, parental care and other reproduction parameters. The focus of the lecture has been placed on the hatchery technology of fish species giving examples of various groups of finfishes and crustaceans in freshwater and marine waters including acquiring broodstock, hatchery facilities, reproduction technology (natural – artificial) and the relation of adopted technologies to the biology of fish as well as the economic considerations. The lecture addressed the quality of hatchery production whether through genetic enhancement or biosecurity measures such as vaccination or disease-free protocols.

Planning of aquaculture projects – 2017 updated

 

This lecture which was delivered today is considered an introductory component of group projects. The lecture addresses technical and economic issues providing case studies. The ultimate goal of this lecture is to focus on necessity of proper planning for achieving successful aquaculture projects. The farmed species in relation to the climatic conditions as well as the consumer acceptance. Also, the proposed site of the project has been analyzed focusing on issues which could be handled versus other issues which could have detrimental effects on the the future of the project. Design, staffing, capacity building, economic analysis, SWOT analysis have been addressed in the lecture.

Development and outlook of Egyptian aquaculture (2017 updated)

 

 

This file is a copy of my very recent lecture on the development and outlook of Egyptian aquaculture. With the support of official figures, I did my best to analyse and predict the mode of development as well as the possible challenge. Among the key figures presented in the lecture is the new rank of Egyptian aquaculture enjoying the seventh rank globally. The leading role of tilapia has been addressed and also the challenges facing marine aquaculture. The institutional framework and governing regulations have been addressed. Typically, this lecture starts and ends with human resources and capacity building.
