“…A comparatively high pH exists in Pond 1, which may be associated with the abundance of Bacillariophyceae, in agreement with the finding of Kumar and Oommen () that acidic water does not support Bacillariophyceae abundance. There was an abundance of Bacillariophyceae in Pond 1 associated with nutrients, particularly phosphate, as per the finding of Tavares et al .…”

Plankton are highly sensitive to environmental changes, therefore being excellent water indicators. This study was conducted to classify water and sediment quality characteristics and different genera of phytoplankton and zooplankton in three ponds. The prominent water and sediment quality characteristics responsible for the occurrence of phytoplankton and zooplankton were also studied. The nutrient pollution factor is mainly responsible for the abundance of Cyanophyceae and for reduction in Rotifera, Cladocera, Copepoda and Ostracoda. The organic pollution factor is responsible for the abundance of Bacillariophyceae and Protozoa. The products of mineralization have more influence on the decreased Chlorophyceae. Thus, it is essential to control the disposal of pollutants into the study pond system.

“…Predominance of Bacillariophyceae species throughout the period under analysis has been associated with alkaline water, because acidic waters do not support an abundance of species and show high activity at relatively low temperature (Allen et al, 2005). Kumar and Oommen (2009) reported that acidic waters do not support an abundance of Bacillariophyceae, whereas their density is higher in alkaline waters, with pH above 8.0, and diatom growth is stimulated by nitrate. In this investigation alkaline pH (between 7.2 and 8.8) except at P 3 in October, and high nitrate concentrations, supported a high population of diatoms.…”

This work was carried out during one year in a fish pond to evaluate the effect of water quality in a plankton community according to the adopted management. High densities of Euglenophyceae, Chlorophyceae and Cyanobacteria were associated with high nitrate levels (1 to 210 mg.L -1 ). Cell densities of Cyanobacteria over 90 ind.m 3 × 10 3 (85.5%) occurred when nitrate concentrations approximated 210 mg.L -1 , total phosphorus less than 160 mg.L -1 and temperature above 25 °C. High density of Rotifera was associated with high density of Cyanobacteria (December). Only Trichocerca sp. among the Rotifera species was constant in all sampled sites, whereas Diaphanosoma birgei, ranging between 4 and 342 ind.L -1 (0.7 and 2.4%) during the study period, was the most representative among the Cladocera species. Results show that water quality management in the fish pond had a direct influence on the plankton population due to the shallowness of the environment, large nutrient discharges through feed, fertilizing, fish waste. In fact, they contribute towards the appearance of undesirable plankton organisms.Keywords: fishpond, phytoplankton, zooplankton, limnology, environment management. Qualidade da água e população planctônica em viveiro de policultivo de peixeResumo O presente estudo foi realizado durante um ano em viveiro de produção de peixes, com a finalidade de avaliar o efeito da qualidade da água na comunidade planctônica em função do manejo adotado. Maiores densidades de Euglenophyceae, Chlorophyceae e Cyanobacteria estiveram associadas aos elevados teores de nitrato (1 a 210 mg.L -1 ). Densidades de Cyanobacteria acima de 90 ind.m 3 × 10 3 (85,5%) ocorreram quando as concentrações de nitrato estiveram ao redor de 210 mg.L -1 , fósforo total menor que 106 mg.L -1 e temperatura acima de 25 °C. Elevada densidade de Rotifera também esteve associada às altas densidades de Cyanobacteria (dezembro). Dentre os organismos zooplanctônicos, os Rotifera foram os mais abundantes e somente Trichocerca sp. foi constante em todos os pontos amostrados. Dentre os Cladocera, a espécie mais representativa foi Diaphanosoma birgei, variando de 4 a 342 ind.L -1 (0,7 e 2,4%) durante o período de estudo. Os resultados mostram que qualidade da água e o manejo empregado neste viveiro apresentaram influência direta na população planctônica, em função da baixa profundidade e constante carga de nutrientes que são incorporados no viveiro por meio de alimentos, fertilizantes e fezes de peixes, que contribuem para o aparecimento de organismos planctônicos não desejáveis.Palavras-chave: viveiros, fitoplâncton, zooplâncton, limnologia, manejo ambiental.

Abstract:An experiment was conducted in glass jars for four weeks to assess the efficiency of fish hydrolysate (FH) of 0.01, 0.05, 0.25, 1.25 and 6.25 (8), cyanophyceae (7) and zooplankton (7) were identified. The results show that FH treatment 0.25 ml L -1 in T-3 enhances the phytoplankton and zooplankton production than other jar waters. So it has been recommended for application in aquaculture ponds as a biofertilizer for the well growth of the plankton species.
