Abstract :
This study was carried out to determine the
plankton interaction with the physico-chemical
parameters of four earthen fish ponds in Musgola Fish
Farm Minna, Niger state. The study was conducted from
March to June; 2021. Samples of Water were analyzed
using standard methods. One-way analysis of variance
with Duncan multiple tests was used to analyze the water
quality parameters. PAST (Multivariate: Canonical
correspondence analysis) was used to evaluate
relationship between plankton communities and
environmental variables. Physico-chemical Parameters
determined include: Biochemical Oxygen Demand,
Alkalinity, Dissolve Oxygen, Nitrate (NO3), Phosphate
(PO4), Sodium(Na),potassium(k), Electricalconductivity,
Air temperature and potential hydrogen. There was no
significant temporal variation in physico-chemical
variables. However, there were slightly change in
parameters throughout the study period. The study
revealed thatzooplanktons were dominated by Cladocera
species (MoinaMicrura) with (43.02%), followed by
Copepod (Cydopoid copepods) with (26.99%) and
Rotifers (Brachionuscalyciflorus)representing7.45%.The
abundance of zooplankton observed in this study can be
attributed to the anthropogenic perturbations on-going
in and around the Fish farm as well as the farmed fish.
Moreover, the presence of suitable zooplankton species is
essential for successful farming. Similarly, seventeen
species of phytoplankton were identified,including
Bacillariophytes, Chlorophytes and cyanophytes. Chlorella
species of the class Chlorophyceae was the most
prevalent group in the four ponds over Bacillariophyceae
and Cyanophyceae.Canonical correspondence Analysis
revealed that physico-chemical variables have positive
influence on the composition and diversityof plankton in
earthen fish ponds at Mosgola Fish Farm. The plankton
community, on which the whole aquatic population
depends, is largely affected by an interaction of a
number of limiting factors such as, moderate sulphate,
nitrate, phosphate and other factors. Variations of the
physical and chemical parameters in a fish pond showed
that the limnological conditions in the fish pond are not
spatially homogenous.Thus, water quality management
in the fish pond expressed direct influence on planktonic
population, since fish ponds are shallow and constantly
receive large nutrient loads (feed, fertilizing, and fish
waste).
