Egypt's aquaculture production (705,490 tonnes in 2009) is by far the largest of any African country and places it 11th in terms of global aquaculture production. The aquaculture sector in Egypt is now a mature one having developed over a period of more than 30 years, but the financial performance of the sector is not well understood or documented, even though value-chain analysis provides a methodological tool to do so.
Details are given of techniques to be used in the handling of large amounts of data in the field of aquaculture. Two examples are given where different types of multivariate data analyses are performed on the compiled datasets to identify and quantify the effects of key variables governing growth and production of fish in manured pond systems cultivating tilapia and carp.
An equation is given for the selection of interval sizes for use in length frequency analysis of fish classes.
A linearized version of the Appeldoorn model of the von Bertalanffy growth function is presented for the estimationof parameters of seasonal growth oscillation.
Details are given of the current database system used by the Collaborative Research Support Programme in PondDynamics/Aquaculture and Its Management. Suggestions are made regarding the design of a database.
Natural resource management is closely linked to conflict management, prevention and resolution. Managing natural resources involves reconciling diverging interests that often lead to conflict, which can undermine management institutions and lead to exploitation, environmental destruction and deteriorating livelihoods. If conflicts turn violent, they can rip apart the entire fabric of society. Thus, managing conflicts in a peaceful manner is decisive not only for successful and sustainable resource management but for societal stability in general.
A method for estimating the instantaneous mortality rate (Z) is presented which was developed from a truncated equation for average length. The model has zero bias at equilibrium, but has no explicit solution for Z so that its solution requires a numerical method.
In many countries, resource conflict is a leading risk to livelihoods. For some communities, it is a matter of survival. Yet, many development interventions aiming to address these challenges fail or fall far short of their potential. Common reasons include conflicting agendas, power and politics; poor local commitment and leadership; lack of coordination; plus high costs and low sustainability, as programs often unravel when development finance ends.
