プロジェクトデータ

NaFIRRI implemented biodiversity informatics projects in the past but freshwater biodiversity data remained in less useful formats. This data was mobilized from data from available in soft and hard copy records at NaFIRRI. The data was collected through multiple projects that took place over the period covered by the data in the Lake Edward system.

タイトル Zooplankton occurrences and abundance in the Lake Albertine system
識別子 BID-AF2020-145-USE
ファンデイング Data collection was funded by the World Bank through the Agricultural Technology and Agribusiness Advisory Services (AATAS), Agricultural Research and Training Project (ARTP II) projects. More funding was from the Lake Albert and Edward Fisheries II (LAEF) project.
Study Area Description This work was part of research and monitoring studies conducted in predetermined localities on water bodies within the Lake Albert system. The area covered Lake Albert and Luzira lagoon while rivers covered were Nkusi, Waki, Muzizi, and Wambabya.
研究の意図、目的、背景など(デザイン) The lake and rivers represent wide portion of Lake Edward system, investigated from 2002 to 2020. The study areas represent multiple habitats based on the depth profile, distances from shoreline covering both lentic and lotic habitats.

収集方法

Zooplankton samples were collected with a conical plankton net (Nansen type; mesh size 60 µm and mouth diameter of 0.25 m), towed vertically through the water column, as described by Fernando (2002) and Mwebaza-Ndawula (1994). Three hauls were taken and combined to make composite samples, preserved in 5% formalin and transferred to laboratory for taxonomic analysis and generation of abundance. In the laboratory, each sample was washed with tap water over a 53 µm sieve to remove the preservative and then diluted to a suitable volume, depending on the concentration of organisms in each sample. Sub-samples of 2, 2, 5 and 10 mL were taken with a wide bore automatic pipette from a well agitated sample. The sub-sample series were performed to consider the more abundant organisms in 2, 2 mL series, and the rarer organisms in 2, 2, 5, 10 mL series. Each sub-sample was put into a counting chamber and examined under inverted microscope (Hund, Wetzlar, Germany) at X100 magnification for taxonomic determination, and X40 for counting and organism body measurements.

Study Extent The water bodies covered were sampled within 2002 to 2020. However, sampling was not consistent for the water bodies over that period. Data is available for specified water bodies for a periods; 2002, 2007, 2013-14, 2016 and 2020.
Quality Control Some zooplankton were able to be identified to species level using published taxonomic keys (Sars 1895; Pennak 1953; Brooks 1957; Rutner-Kolisko 1974; Koste 1978; Boxshall & Braide 1991; Korinek 1999). Taxonomic names were cross-checked using the World Register of Marine Species (WoRMS). Volume densities of organisms were calculated from the counts data, with reference to the sample net mouth diameter and water column depth at each sampling site as per Fernando (2002).

Method step description:

  1. Collection of the zooplankton A conical plankton net (Nansen type; mesh size 60 µm; mouth diameter 0.25 m) was used to collect the zooplankton. It was towed vertically through the water column to have an integrated sample. Three hauls were taken per site and were combined to make a composite sample. Preserving the samples Samples were preserved in a sugar-formalin mixture. The sugar was to stop the ballooning of cladocerans for easy identification. Identification of zooplankton taxa In the laboratory, samples were washed using a sieve of 53 µm to remove the fixatives. Organisms were identified to the smallest taxonomic level possible using taxonomic keys (Sars, 1895, Pennak, 1953, Brooks, 1957, Rutner-Kolisko, 1974, Koste, 1978, Boxshall and Braide, 1991, Korinek, 1999). Density of organisms were calculated from the counts data, with reference to the sample net mouth diameter and water column depth at each sampling site.
