Sumithion usage in aquaculture: benefit or forfeit?

Abstract

Sumithion is an organophosphate insecticide, extensively used to remove tiger bug from aquaculture ponds prior to the release of fish larvae. Its usage in aquaculture may initially assist in insect eradication; however, the harmful effects of sumithion may surpass the beneficial effects and may be alarming for the farmed fish and other aquatic organisms. This study summarizes the consequential effects of sumithion on the natural productivity in aquaculture ponds, and early development, physiological response, and reproductive functions of the farmed fish. Studies have found that sumithion adversely affects the natural production of phytoplankton, zooplankton and benthos, and reduces the hatching success with increased mortality, and morphological alterations in fish embryos and larvae. Fish haematological and biochemical alterations are also reported to be induced by the exposure to sumithion, as are variety of histopathological alterations and reproductive dysfunctions in exposed fish. Overall, this study is the first comprehensive overview of any insecticide which may advance our understanding of the rational and restricted use of insecticide in aquaculture operations.

Vitamin E supplementation in diet ameliorates growth of Nile tilapia by upgrading muscle health

“…Physiological state, immunity and well-being of fish are determined by hemato-biochemical indices ( Ashaf-Ud-Doulah et al, 2020 , Islam et al, 2020a , Islam et al, 2020b , Shahjahan et al, 2020 , Sharmin et al, 2016 , Suchana et al, 2021 , Shahjahan et al, 2021 , Shahjahan et al, 2022 ). The current study revealed that VE provision in diet did not significantly influence the fish hematology.…”

Response and recovery of Nile tilapia exposed to diesel oil – Behavioral, hemato-biochemical and morphological changes of erythrocytes

“…Hematological and biochemical parameters are considered as decent indicators to know whether the fish are in stressful conditions because of aquatic environmental pollutants [13] , [41] . We found moderate to severe aberration of hemato-biochemical parameter in our sample treated with diesel and in every case the sample exposed to higher dose (0.5 mL/L) showed greater anomaly compered to lower dose (0.1 mL/L).…”

“…Subsequently, the investigation of oil exposure of fish has gotten importance in the last few decades and researchers have observed the long-term consequences of petroleum hydrocarbons on feeding, growth, behavior, reproduction, and tissue damage of fish [7] , [8] , [9] , [10] . Change in blood parameters can be used for determining the health status of fish [11] , [12] , [13] , [14] . For instance, hemoglobin (Hb) transports oxygen to diverse tissues in most cases, hence the Hb concentration of the blood is frequently utilized to determine anomalies and pathological indicators of fish health [15] , [16] .…”

Bioaccumulation and Bioremediation of Heavy Metals in Fishes—A Review

“…Bioremediation is a convenient and ecofriendly option that can be used to restore the contaminated environment by removing toxic metals from the environment [ 224 , 229 ]. Bioremediation of toxicants can be done by adsorption [ 230 , 231 , 232 ], physio-biochemical mechanisms [ 233 , 234 , 235 , 236 ], and molecular mechanisms [ 237 , 238 , 239 ]. Several enzymes (superoxide dismutase, SOD; catalase, CAT; glutathione S transferase, GST) and nonenzymatic compounds (reduced glutathione, GSH) play a key role in sustaining the ROS balance by detoxification ( Figure 2 ).…”
