A report of the fisheries catch assessment survey (CAS) in the Ugandan waters of Lake Victoria for July 2005

This report presents findings of the first CAS in the Ugandan waters following the agreed SOPs, carried out in July 2005. The findings indicate a total fish catch of 15,047.5 t for July 2005, contributed by Mukene/Dagaa (39.5%), Nile perch (33.1%), Tilapias (17.1%), Haplochromines (9.2%) and other fish species 1.2%. This information gives a new perspective of the estimates of fish production in the Ugandan waters of the lake which are based on field observations. Continuation of support to the CAS programme will certainly get rid of the uncertainties about the fish production levels of the lake which have been there for a long time. This information is vital for fisheries development and fisheries management endeavours.

Information models used to manage engineering change: A review of the literature 2005-2010

Engineering change is a significant part of any product development programme. Changes can arise at many points throughout the product life-cycle, resulting in rework which can ripple through different stages of the design process. Managing change processes is thus a critical aspect of any design project, especially in complex design. Through a literature review, this paper shows the diversity of information models used by different change management methods proposed in the literature. A classification framework for organising these change management approaches is presented. The review shows an increase in the number of cross-domain models proposed to help manage changes.
