Effects of Different Diets on Population Growth of Cultured Cyclopoid Copepod, Mesocyclops leuckarti (Claus, 1857)

Abstract

In recent times aquaculture has become an increasingly important part of the world economy. Copepods play major roles in pond ecosystems serving as food for small fish, micro-predators on fish and other organisms, fish parasites, intermediate hosts of fish parasites and hosts and vectors of human diseases like cholera. Growth, reproduction and biochemical composition were analyzed for the copepod Mesocyclops leuckarti fed on four diets and their ratio like Bakers yeast (B), Baker’s yeast+ Wheat flour (BW, 1:2), Bakers yeast + Chicken manure (BC, 1:2) and Bakers yeast + Chicken manure + Wheat flour (BCW, 1:2:2). The mean peak density of the copepod population was 569 individual/lit, for all four diets used. The highest was 587 individual/lit, on diet having combination of Bakers yeast, Chicken manure and Wheat flour (BCW). A small copepod Mesocyclops leuckarti tends to have a short life span and it was found to be important food items for fish larvae.

Effects of warming on the structure of aquatic communities in tropical bromeliad microecosystems

“…Ecologically, copepods are an important prey in the diets of commercially important larval, juvenile fish, and invertebrates, playing key roles in the transfer of organic matter (Atul & Rumana, 2021; Marcus, 2004; Montero et al, 2021). Because of this function, copepods can be used as a natural food for fish and as a viable alternative of high quality and easily digestible food (Atul & Rumana, 2021). However, the copepod density in bromeliads was strongly influenced by the combined effects of warming and bromeliad water volume.…”

“…Copepods comprise the dominant zooplankton taxa in most water bodies worldwide, and are one of the most important bioindicators for globally (Magouz et al, 2021). Ecologically, copepods are an important prey in the diets of commercially important larval, juvenile fish, and invertebrates, playing key roles in the transfer of organic matter (Atul & Rumana, 2021;Marcus, 2004;Montero et al, 2021).
