The relationship between phytoplankton primary production and seasonality of physico-chemical parameters were examined for five man-made lakes in the dry-zone of Sri Lanka. Sri Lanka experiences two monsoons dividing the year into four meteorological seasons: -the North East (October-December) and South West (April-June) monsoons and the two inter-monsoons. A significant log linear relationship was found between Secchi disc depth and the depth of the euphotic zone which was lowest during the NE monsoon. Maximum mean photosynthetic rate ranged from 0.935 t-0.067 SE to 0.479 mg 021-I h-I k 0.115. Gross primary productivity which ranged from 0.378 g 0, m-2 h-I in the NE monsoon to 0.980 g O2 rn-, h-' in the SW monsoon showed significant season variation. This is shown to be determined either directly or indirectly by the light regime.

“…Productivity rates (mean value of 4.86 g C m −2 day −1 ) in Panyam fishpond are higher than those reported by Talling (1965) for some African freshwater bodies (1–3 g C m −2 day −1 ). Still higher values (mean value of 9 g C m −2 day −1 ) have been documented by Sreenivassan (1964) for a tropical pond in India. Khan and Agugo (1990) estimated a low mean production value (1.04 g C m −2 day −1 ) for a tropical impoundment in West Africa.…”

“…Determination of primary production in fishponds, as an index of organic production, and its practical considerations in regard to fisheries, has long been recognized (e.g., Hepher 1962; Sreenivassan 1964). Thus, pond water ecosystems have attained special importance in regard to fishery management over the years.…”

Compared to the East ⁄ Central regions of Africa, little research efforts have focused on West African tropical limnology. This study, conducted on a freshwater ecosystem, Panyam fish pond, in the highland region (Plateau State) of tropical West Africa, provides knowledge on the hydrochemical characteristics and seasonal or annual biomass oscillations corresponding to the distinguishable climatic phases characteristic of the region. Physiographic phenomenon 'Harmattan' (North-East Trade Winds) induced low temperature conditions (<11°C) during December to January. Moderately dilute waters are reflected by relatively low ionic content (average conductivity of 77 lS cm )1 ), conforming to the category II of African waters, based on the classification of Beadle (1981). Seasonal algal succession was marked by its abundance relative to the beginning of the rainy season (May to September). The sequence of annual phytoplankton dominance was Chlorophyceae>Cyanophyceae>Bacillariophyceae. The dominance for zooplankton was Rotifera>Crustaceae. The occurrence of fewer Cladocera and Copepoda in the Panyam pond is an observation consistent with the findings for other tropical water systems. These results further support the contention that seasonal or annual biomass oscillations in the tropics are not systematically lower than in the temperate zone. The observed phytoplankton productivity rates (average value of 4.86 g C m )2 day )1 ) are higher than those reported by Talling (1965) for African waters. A considerable proportion of the net production (64.3%) was comprised of gross production (1760 g C m )2 day )1 ). The observed relatively enhanced respiratory values (25.4-41.5%) are characteristic of tropical waters. Further, more robust studies will work to remedy the paucity of knowledge regarding tropical West African limnology.

Gross and net primary production together with chlorophyll-a biomass were investigated with respect to depth and diurnal changes in three categories of inland waters (reservoirs, temporary ponds, brackish water lagoons) in Sri Lanka. Ten field sites, in both the dry and wet zones of the island, were investigated. Bimodal productivity profiles were recorded in two of the three reservoirs studied. The die1 pattern of net photosynthetic rate varied between sites although peak photosynthetic efficiency occurred at solar noon. Surface photoinhibition was characteristic of the reservoirs and brackish water lagoons but not of the temporary ponds. Mean gross primary production was 3.02 g C m-2 d-' but was higher in the temporary ponds than in the reservoirs. The gross primary production in the brackish water Koggala Lagoon at 0.08 g C m-2 d-I is a record low for tropical lagoons and was 2.5 times less than the two other lagoons investigated. Variability in net primary production between sites was similar to the variation in gross production with a relatively low mean value for tropical inland waters of 0.495 C m-2 d-'. Mean maximum photosynthetic rate was 0.30 mg C m-3 h-I but was lower in the reservoirs than in the temporary ponds and lagoons.
