Determination of phytoplankton species in the Stomach of Tilapia Fish (<i>Oreochromis niloticus</i> L.)

Abstract

The condition of a fish pond's physiochemical parameters determines whether it is artificial or natural. One of the most significant  tropical and subtropical freshwater fish is the tilapia (Oreochromis niloticus L.), which can eat both tiny zooplankton and phytoplankton.  The purpose of this investigation was to determine the phytoplankton species found in the stomach and gut of tilapia (Oreochromis  niloticus L.). Based on the physical traits of the phytoplankton species, fishpond waters, fish guts, and fish stomachs were identified using  established procedures. The conventional techniques were employed to measure the physicochemical characteristics.  Cyanophyceae and Chlorophyceae made up the majority of the phytoplankton that was discovered in the stomach, gut, and pond waters. Anabaena and Microcystis, two potentially poisonous cyanophyta species, were the most significant and prevalent phytoplankton species  discovered in the intestines of tilapia. The study area's fish pond water had physicochemical parameter values of 26.3 o/oo for salinity, 7.1  for pH, 6.3 mg/L for dissolved oxygen, and 27.4°C for temperature. The study's findings may be applied to the biomanipulation of  bothersome phytoplankton blooms in pond environments. The variation in the gut and stomach phytoplanktons of Tilapia fish was thus  shown by the current preliminary investigation, which may be helpful in the creation of probiotics, medications, and industrial enzyme  production. The pond under study was steady and appropriate for fish farming, with the goal of reintroducing fish to areas with a  deficiency of fish populations.
