Abstract
The toxicity of microplastics (MPs) to fish has become a global
problem. Now a days more or less amount of Microplastics are found in all
aquatic environments and they may have an impact on the freshwater and aquatic
biota's ability to feed, grow, reproduce, and survival and also cause tissue
damage, oxidative stress, and changes in immune-related gene expression as well
as antioxidant status in fish. About 71% of the earth surface is occupied by
oceans, which holds 97% of the earth’s water. The remaining 3% is present as
water in ponds, streams, glaciers, ice caps, and as water vapor in the atmosphere.
Microplastics can leach out chemicals and act as transport vectors by
accumulating dangerous pollutants from the environment. Around 54.5% of
microplastics floating in the ocean are polyethylene, and 16.5% are
polypropylene and the remaining materials include polyester, polyvinyl
chloride, polystyrene, and polyamides. Moreover, polyethylene and polypropylene
are less dense than sea water, so they float and have an impact on aquatic
surfaces. Therefore, it is important to understand the ecotoxicological impacts
and mode of action of environmentally relevant MP concentrations on the health
of aquatic organisms. Scientific knowledge is always expanding at a rapid rate,
despite the fact that evidence of actual adverse effects is still extremely
limited now a daysit is also necessary to have some research models that
investigate the effects of realistic exposure scenarios at the individual and
population levels. The large amount of data currently available for favourable
treatment of ongoing management and legislative measures that focus on reducing
the production, consumption, and discharge of microplastics into the world's
aquatic freshwater. In the present study, we conducted a systematic review of
behavioural, Locomotion, aggression, feeding and swimming, immunotoxicity,
neurotoxicity and reproductive and developmental effects caused by fish
consuming environmental microplastics at different life stages and also suggest
some different mitigation strategies of microplastics for future.
