Extensive study and data collection on the pituitary gland: A promising prospect revealed by surveying the fish market during the monsoon season

Fish is a vital source of protein in India, and the Indian fishing industry plays a pivotal role in the nation’s economy. India ranks as the world’s second-largest fish producer, yielding approximately 4.3 million metric tons of fish annually. To meet this high demand, fish production continues to rise, resulting in a significant amount of fish waste. In India, nearly 2 million metric tons of fish waste are generated annually, with West Bengal contributing a substantial 1,770.310 tons in 2019. Our research concentrates on the Madanpur and Simurali fish markets in the Nadia district. These markets generate substantial quantities of fish waste, often mismanaged due to the lack of awareness among fishermen. Various forms of waste, including fish scales, swim bladders, and fins, are prevalent. Our survey report underscores the need for proper management of these waste materials to ensure sustainable growth and mitigate the environmental pollution resulting from fish waste. Fish scales, in particular, serve as a valuable source of chitin and collagen, finding applications in cosmetics, pharmaceuticals, and the food industry. Additionally, fish waste can be processed into fish food, offering a balanced diet for Thai Magur and ornamental fishes. In today’s context, it is imperative to educate stakeholders about fish waste management and raise awareness about the adverse environmental impact of neglecting this critical issue. By addressing these challenges, we can harness the full potential of the Indian fishing industry while promoting environmental sustainability.

Fish and the fishery economy play a pivotal role in global sustenance and economic stability. Understanding the impact of physicochemical parameters and heavy metal toxicity on Tilapia reproduction is imperative for achieving the Sustainable Development Goals (SDGs). Numerous water bodies, referred to as “bheri,” located in North 24 Parganas, are grappling with substantial environmental contamination. The pollution in this region stems from diverse industrial, sewage, agricultural, and petroleum activities prevalent in the area. Consequently, investigating the contamination of fish with heavy metals becomes imperative for the well-being of the populace residing in a country surrounded by water bodies. This study aims to ascertain and compare the concentrations of heavy metals (Lead, Cadmium, Mercury, and Copper) in distinct water samples obtained from various zones within North 24 Parganas. The current investigation seeks to explore the impact of physicochemical parameters and the toxicity of heavy metals on the reproductive processes of tilapia collected from diverse sampling sites in North 24 Parganas. The samples were categorized into two groups: one from severely polluted water bodies (designated as the intoxicated group) and the other from uncontaminated water bodies (designated as the control group). The results revealed a noteworthy disparity between the intoxicated group and the control group. The histological examination of fish organs (Ovary, testes, and brain) was documented. In the testes of the intoxicated group, degenerative changes and a reduced number of seminiferous tubules were observed. The ovaries exhibited deformities in their normal shapes, and severe lymphocytic infiltration, and the brain displayed neuronal degeneration along with a significant loss of granular cells. Hence, our present investigation aims to raise awareness within communities regarding the environmental pollution affecting edible aquatic organisms. We advocate for the enhancement of water quality in these water bodies and the implementation of government laws and regulations about the safeguarding of these aquatic environments.
