Abstract High levels of heavy metals in the environment pose a significant risk to aquatic ecosystem and its organisms. The non-biodegradable nature lengthy persistence lead toxicity shrimp. Using animals as bio-indicators metal contamination provides valuable data on acute chronic species environmental quality. This review aims provide insights into sources, impacts, diseases mitigation strategies related pollution shrimp farming dangers humans. Shrimp growth development at each stage exhibit distinct responses toxicity, which can vary depending species, types metals, their mechanisms action, well concentration duration exposure. While several are considered essential nutrient elements that enhance feed efficiency, exceeding maximum tolerable limit threatens health, human consumers, ecological systems’ stability. subjected lethal toxic concentrations experience effects accumulation histopathology. Heavy has been linked high mortality rates, malformation oxidative stress, moulting issues, decreased reproduction with increasing Various methods have reported for removing ions from environments, including filtration, adsorbents, removal efficacy, operating conditions, pros cons technique. Therefore, this an overview how affect physiology consumers. It increase awareness about importance preventing regulating environments.

Behavioral, biochemical, immune, and histological responses of Nile tilapia (Oreochromis niloticus Linnaeus, 1758) to lead, mercury, and pendimethalin exposure: individual and combined effects

Environmental Sciences Europe, Journal Year: 2025, Volume and Issue: 37(1)

Published: Jan. 15, 2025

Abstract The aquaculture sector is facing environmental issues because of rising chemical pollution aquatic systems, which may be caused by man-made or natural causes. combined action these mixtures can produce an effect that either severalfold higher lower than the overall toxicity individual components. objective this study to evaluate impact three toxicants: lead (Pb 0.088 mg L −1 ), mercury (Hg 0.084 and pendimethalin (PM 0.355 ) their combinations on behavior, oxidative stress, immunology, biochemistry, histopathological changes in Nile tilapia. results show mortality was evident across all treatment groups highest mixture (MIX) group, at 33.4%. Some behavioral included increased mucus secretion, fin rot, dark skin coloration fish, were evidently exacerbated MIX group. erythrocyte hemoglobin indices presented marked reductions PM comparison control group had levels serum creatinine urea, as well liver enzymes alanine aminotransferase, aspartate transaminase, alkaline phosphatase. They also malondialdehyde total antioxidant capacity, showed stress. stress biomarkers, cortisol glucose, greater groups. neurobehavioral assessment demonstrated noticeable decreased acetylcholinesterase MIX-exposed In immunological parameters, nitric oxide lysozyme lower, especially experimental groups, spleen pro-inflammatory cytokine genes higher. examination revealed lesions gills, liver, brains form inflammation, necrosis, circulatory alterations. Among exposed exhibited changes. Collectively, our findings significant toxic effects heavy metals herbicides tilapia, revealing a synergistic both physiological responses resulting from exposures. data indicate ecological hazards associated with ecosystems.

Effect of selenium and nano-selenium applications on biological functions in aquaculture: a review

Annals of Animal Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 15, 2025

Abstract Selenium plays a crucial role in vital physiological processes for fish, by involved many of cellular metabolism and increase the growth performance health status fish. Nano-selenium (nano-Se) has been shown to promote fish more than other traditional inorganic Se forms. Additionally, increased capacity absorb various nutrients, provided protection from pathogens. In general, growth, hematological, biochemical immune characteristics improved with incorporation dietary selenium. When fed small amounts, can also function as an antioxidant. There is need research on use supplement diets aquatic species since there are few variables that could affect levels make it difficult estimate its required levels. The actual bioavailability nanoparticles needs be determined. This review have tried evaluate draw conclusions about advantages forms potential application mineral animal’s different biological functions.

Toxicological Effects of Waterborne Boric Acid and the Protective Role of Dietary Black Cumin (Nigella sativa L.) Oil in Nile Tilapia (Oreochromis niloticus): Hematological, Biochemical, Oxidative Stress and Histopathological Responses

Published: April 28, 2025

This study aimed to evaluate the protective effects of dietary black cumin (Nigella sativa L.) oil on hematological, biochemical, oxidative stress, and histopathological responses in Nile tilapia (Oreochromis niloticus) exposed waterborne boric acid. After determining 96-hour LC₅₀ value acid, experimental design included exposure 1/20th this concentration. Fish were fed for 21 days with diets either containing or lacking 1% oil. At end feeding trial, blood parameters, stress biomarkers, tissue histopathology analyzed. The group receiving without acid showed most favorable physiological biochemical profiles. In contrast, alone exhibited significant negative alterations. Importantly, fish while improvements across all measured parameters compared toxicant-only group. findings indicate that effectively alleviates toxic tilapia, supporting its potential use as a functional additive aquaculture.

Comparison of the potential risk from arsenic exposure when eating fish grown in natural and artificial conditions, using the example of rainbow trout

Toxicological Review, Journal Year: 2024, Volume and Issue: 32(5), P. 307 - 312

Published: Oct. 30, 2024

Introduction. Due to the increasing share of fish and products in human diet, hygienic problems are also increasing, especially with growing aquaculture sector. The task determining level arsenic toxicity is becoming extremely important. Although mechanisms inorganic generally well understood, impact speciation its other (organic) compounds on likelihood carcinogenic non-carcinogenic effects has been largely unexplored. Material methods. objects study were samples fillet caviar salmon – rainbow trout (wild aquaculture). quantitative determination arsenic-containing substances was carried out using high-performance liquid chromatography-mass spectrometry inductively coupled plasma. prepared microwave risk calculated based recommendations R 2.1.10.3968–23. Results. As result this work information about concentration (organic compounds) fillets from family - shown. It established that content organic practically does not differ, depending habitat trout. levels calculated. Limitations. Determination trout, which had grown natural artificial conditions. Conclusion. makes greatest contribution health risk. However, magnitude exceed acceptable sanitary standards, while conditions for have no effect these values.

The problem of clean water is one the most important environmental problems in world. It impossible to prevent occurrence adverse situations without careful monitoring aquatic ecosystems state. assessment current chemical composition Volga-Akhtuba floodplain shallow channels (Peschanyj, Dudak, and Dudachenok) water-bottom sediments system was carried out. Studied dried out during summer-autumn lowwater period for last few decades. Studies were after clearance ecological rehabilitation channels. found that almost all studied indicators samples correspond established quality standards. There uneven distribution heavy metals can be caused by influence hydrodynamic conditions, changes sediment flow, as well local factors, including catchment heterogeneous geology. analysis content bottom with permissible ones made it possible detect excess Hg (0.18?0.75 mg/kg), Cd (1?2.12 Mn (370.8?493.3 Ni (2.6?67.9 Pb (14.3?22 Zn (75.2?147 mg/kg). As (1?1.4 mg/kg) Cu (8.54?28.7 does not exceed concentrations. obtained results will form basis a general comprehensive watercourses. necessary continue watercourses state strengthen efforts preserve resilient ecosystem floodplain.
