Animal Science in Zimbabwe: Strategies and Solutions

Animal Science involves a scientific understanding of farm livestock. The subject is made up of a number of scientific disciplines such as nutrition, genetics, physiology and a few others such as microbiology, which are of lesser importance but which are increasing in relevance. It is acceptable therefore, to teach and review Animal Science by considering each of these disciplines. Unfortunately, this treatment of the subject may well mask wholly or partially important interactions between the disciplines although an attempt will be made to discuss those of the greatest importance. An alternative way to write a comprehensive review is to base it on type of livestock, viz. beef cattle, dairy cattle, pigs, etc. (Ndlovu, 1994a) so this approach is also incorporated in this paper.

An innovative approach to monitoring the physical stability of constructed fish habitat using drones

In August 2014, a subsurface failure at the Mount Polley mine’s tailings storage facility resulted in a debris flow that scoured Hazeltine Creek and a portion of Edney Creek. Creek rehabilitation planning, design and construction commenced immediately following the incident. A two-phased approach was adopted to reconstruct the creek and restore habitat for fish and riparian wildlife. The first phase was to construct an erosion-resistant engineered channel to control erosion and reduce turbidity in water entering Quesnel Lake. The second phase was to re-establish physical in-stream and riparian habitat along the channel to support a return of biological habitat function. Following the construction of habitat features in sections of Hazeltine Creek and Edney Creek, drone imagery was used to georeference the locations of the constructed habitat. The aerial imagery had sufficient resolution to geospatially document each element of stream habitat, and therefore monitor its physical stability. This novel habitat monitoring technique couples the aerial imagery from drones with geographic information system (GIS) software to reliably determine the stability of each element of habitat and develop a database of those habitat elements. This combination of technologies enables an effective, relatively rapid and low-cost means of monitoring constructed fish habitats.Non UBCUnreviewedOthe
