Dados Sobre o Projeto

The project aimed at investigating dynamics in the ecology and fisheries of Lake Victoria in relation to cage aquaculture development.

Título CNH-L: The Potential for Aquaculture in Lake Victoria and Implications for Wild Fisheries and Fish Commodity Markets
Identificador 1518532
Financiamento This project was funded by a National Science Foundation (NSF) grant to the University of Denver and the Lake Victoria Fisheries Organization (LVFO).
Descrição da Área de Estudo The survey was carried out in both the Northern portion of Lake Victoria, Uganda.
Descrição do Design The study was designed to cover major habitats of haplochromine cichlids in the Ugandan portion of Lake Victoria. The habitats include rocky (only for gill netting), sandy, muddy, and vegetated areas. Also, sites near fish cage installations were identified and sampled to get an indication of impact of cage aquaculture on fish distribution.

Métodos de Amostragem

Bottom trawling and gillnetting were carried out at selected stations, with varying habitat characteristics, in 2017 using the research vessel R.V. Hammerkop and graded monofilament/multifilament nets, respectively. For the bottom trawling, hauls of 30 minutes duration were taken using a 25.4 mm cod-end stretched mesh trawl net in the various grids (see LVFO 2007 for standard operating procedures), towed at 3.4 knots. For gillnetting, two fleets of graded monofilament gillnets of mesh size 0.75”, 1.00”, 1.25”, 1.50” and 2.00” were soaked and retrieved at 30 minute to two hour intervals. On retrieval, fish were removed according to mesh size, separated into labelled buckets filled with water and transported back to the shore or research vessel (for the trawl survey) for further processing. At the shore or aboard the research vessel, identical fish species in each bucket were lumped together. Photographs of live specimens were taken using a digital camera. The left side of each live fish was photographed inside a photo cuvette that had a colour bar and label attached to its background using masking tape and was filled with water (up to ¾ of total volume). The rare and unique species were photographed first before the other specimens in the rest of the catch. After taking the photographs, the fish specimens were euthanized using a solution of MS-222 or clove oil, tagged, and fin clips and tissue samples obtained for genetics and stable isotopes respectively. For DNA samples, fin clips were obtained from the right pectoral fin of individuals of unidentified fish species and placed into plastic vials filled with 99% ethanol solution, and sent to Switzerland (Eawag) for full genome sequencing and further identification. Fish species that could not be identified to species level were given cheironyms.

Área de Estudo The study covered parts of the Northern Lake Victoria, Uganda, between April and August 2017.

Descrição dos passos do método:

  1. Photos were taken to facilitate identification of fish specimens, and identification of fish was done by an expert (Ole Seehausen) with over 30 years’ experience in taxonomy of Lake Victoria fishes, especially haplochromine cichlids .
