Spatial and temporal scales of the coastal currents in the St. Helena Bay - Cape Columbine Region
… shelf dynamics programme undertaken by the Sea Fisheries Research Institute, attempts to identify the important time and spatial scales within the coastal currents and to investigate the relationship between the sub-inertial flow and low frequency variations in the coastal winds.

Tracking the movement of fish: skipper's logbooks and marine knowledges in fisheries management
Experts in both the line-fisheries and fisheries science sectors specialise in tracking the movement of fish. The knowledge thus gained is integral to both fishing practice and fisheries research, yet the two have often been posited against each other on opposite sides of a spectrum. This …

The effects of acute handling stress on the secondary stress responses of striped bass (Morone saxtilis) and its hybrid (Morone chrysops x Morone saxtilis)
… the stress response can not be underestimated in fisheries research or the aquaculture industry. Three studies were undertaken to quantify the secondary stress responses of striped bass and its hybrid. These were measured as fluctuations in glucose, glycogen, lactate, and osmolality. Fish were …

Return to the realm of the Kob Kings: social capital, learning, resilience and action research in a changing fishery
… thinking, and directed by a participatory action research approach, the work facilitated the co-development of a series of applied responses to local challenges identified by research participants including commercial linefishers, school learners, teachers, and other local community members. The …

Fishes of the genus Lutianus off the East African coast and Part 2: Notes on the biology of the Lutjanids of the East African coast
… Routine work of the East African Marine Fisheries Research Organization has produced over 1,000 specimens for study. The Organization's vessel, the M.V. "Research", has collected by handlines, multiple trolling lines, gill nets, deep lines and basket traps over the six hundred mile …

Egg cannibalism by anchovy in the Southern Benguela Current Region
… adult anchovy and plankton were collected on Sea Fisheries Research Institute R.S. Africana 1984-1985 anchovy spawner biomass estimation cruises. A total of 40 sets of anchovy samples of 30 fish each and 40 plankton samples were taken roughly at the same time within an area of intensive spawning …

Combining Balanced Score Card and Data Envelopment Analysis for Analyzing the Performance of Small Scale Fisheries
… Performance Indicators (KPIs). In the commercial fisheries sector, sustainable strategy of fisheries organizations can be gained by running the current operations more effectively, and by integrating processes enabling adaptation to change. The efficiency frontier of the DEA model can be used to …

Hydraulic and biological aspects of fish passes for dams
… physical models were constructed, one at the Fisheries Research Services Freshwater Laboratory at Almondbank, Perth, Scotland where observations were made of fish behaviour. The other model at the University of Glasgow, Glasgow tested only hydraulic conditions. The physical models were …

Yellow perch in Lake Michigan: investigating size-selective mortality and alternative estimators of age
… dynamic of fishes is a critical component of fisheries research and management. However, the interplay of both biotic (i.e. spawning stock biomass and predation) and abiotic (i.e. water temperature and currents) factors throughout pre-recruit life stages makes recruitment predictions …

Environmental evaluation of alternative options for the disposal of oily waste following a marine oil spill off the South African coast and development of a decision strategy
… the South African Coast undertaken by the Sea Fisheries Research Institute of the Department of Environment Affairs, has revealed that alternative disposal methods for oily waste need to be investigated in order to cope effectively and timeously with a major oil spill. Current techniques …

Evaluation of sampling methodologies for assessing fish species richness in ridge and valley streams in Chattanooga, Tennessee
I evaluated the adequacy of different electrofishing approaches for estimating species richness in small Ridge and Valley streams. My study objectives were to determine the effects of the sampling season, reach length, habitat sequences surveyed, and sampling intensity on estimates of fish species …

A framework for building spatiotemporal applications in Java
… PJama (Persistent Java) system for the local Sea Fisheries Research Institute in our department [SVZ98]. How will spatiotemporal data be represented, what methods are necessary for manipulating the data, and where would spatiotemporal data and methods be positioned in the overall structure of the …

Ecology of White-Tailed Deer in South Dakota: Growth, Survival, and Winter Nutrition
… 2005. Deer were maintained at the Wildlife and Fisheries Research Facility at South Dakota State University. Sixty-one fawns were born during this study and averaged 3.6 kg at birth. Daily growth rates of fawns (pre-weaning) averaged 0.16 kg. At sixteen months-of-age deer weighed an average of …
