Aquaculture is the practice of cultivating aquatic organisms, encompassing fish, crustaceans, mollusks, and plants, in controlled environments such as ponds, tanks, or cages. This industry plays a vital role in meeting the increasing global demand for seafood while alleviating pressure on wild fish stocks. Various methods, including fish farming, shrimp cultivation, and shellfish farming, are employed to rear and harvest aquatic species. Aquaculture contributes significantly to the economy, providing food security, employment opportunities, and export revenue. While promoting sustainability through practices like Integrated Multi-Trophic Aquaculture (IMTA), it faces challenges such as disease control and environmental impact. Overall, aquaculture serves as a crucial solution for sustainable seafood production, balancing the needs of a growing population with environmental stewardship.

L'aquaculture est la pratique consistant à cultiver des organismes aquatiques, notamment des poissons, des crustacés, des mollusques et des plantes, dans des environnements contrôlés tels que des étangs, des réservoirs ou des cages. Ce secteur joue un rôle essentiel pour répondre à la demande mondiale croissante de produits de la mer tout en réduisant la pression sur les stocks de poissons sauvages. Diverses méthodes, dont la pisciculture, la crevetticulture et la conchyliculture, sont employées pour élever et récolter les espèces aquatiques. L'aquaculture contribue de manière significative à l'économie, en assurant la sécurité alimentaire, en créant des emplois et en générant des recettes d'exportation. Tout en promouvant la durabilité grâce à des pratiques telles que l'aquaculture multitrophique intégrée (AMTI), elle est confrontée à des défis tels que la lutte contre les maladies et l'impact sur l'environnement. Dans l'ensemble, l'aquaculture constitue une solution cruciale pour la production durable de produits de la mer, en conciliant les besoins d'une population croissante et la gestion de l'environnement.

Unter Aquakultur versteht man die Aufzucht von Wasserorganismen wie Fischen, Krebstieren, Weichtieren und Pflanzen in kontrollierten Umgebungen wie Teichen, Becken oder Käfigen. Diese Industrie spielt eine wichtige Rolle bei der Deckung der weltweit steigenden Nachfrage nach Meeresfrüchten und mildert gleichzeitig den Druck auf die Wildfischbestände. Für die Aufzucht und Ernte aquatischer Arten werden verschiedene Methoden eingesetzt, darunter Fischzucht, Garnelenzucht und Muschelzucht. Die Aquakultur leistet einen wichtigen Beitrag zur Wirtschaft, indem sie Ernährungssicherheit, Beschäftigungsmöglichkeiten und Exporteinnahmen bietet. Obwohl sie durch Praktiken wie die Integrierte Multi-Trophische Aquakultur (IMTA) die Nachhaltigkeit fördert, steht sie vor Herausforderungen wie der Krankheitsbekämpfung und der Umweltbelastung. Insgesamt ist die Aquakultur eine wichtige Lösung für die nachhaltige Produktion von Meeresfrüchten, die den Bedarf einer wachsenden Bevölkerung mit dem Umweltschutz in Einklang bringt.

A aquacultura é a prática de cultivar organismos aquáticos, incluindo peixes, crustáceos, moluscos e plantas, em ambientes controlados, como lagos, tanques ou gaiolas. Esta indústria desempenha um papel vital na satisfação da crescente procura mundial de produtos do mar, aliviando simultaneamente a pressão sobre as unidades populacionais de peixes selvagens. São utilizados vários métodos, incluindo a piscicultura, a cultura de camarão e a cultura de marisco, para criar e colher espécies aquáticas. A aquicultura contribui significativamente para a economia, proporcionando segurança alimentar, oportunidades de emprego e receitas de exportação. Embora promova a sustentabilidade através de práticas como a Aquicultura Multitrófica Integrada (AIMT), enfrenta desafios como o controlo de doenças e o impacto ambiental. Globalmente, a aquicultura é uma solução crucial para a produção sustentável de produtos do mar, equilibrando as necessidades de uma população em crescimento com a proteção do ambiente.

L'acquacoltura è la pratica di coltivare organismi acquatici, tra cui pesci, crostacei, molluschi e piante, in ambienti controllati come stagni, vasche o gabbie. Questa industria svolge un ruolo fondamentale nel soddisfare la crescente domanda globale di frutti di mare, alleviando al contempo la pressione sugli stock ittici selvatici. Per allevare e raccogliere le specie acquatiche si utilizzano diversi metodi, tra cui l'allevamento di pesci, gamberi e crostacei. L'acquacoltura contribuisce in modo significativo all'economia, fornendo sicurezza alimentare, opportunità di lavoro e ricavi da esportazione. Pur promuovendo la sostenibilità attraverso pratiche come l'acquacoltura multitrofica integrata (IMTA), deve affrontare sfide come il controllo delle malattie e l'impatto ambientale. Nel complesso, l'acquacoltura rappresenta una soluzione cruciale per la produzione sostenibile di frutti di mare, in grado di bilanciare le esigenze di una popolazione in crescita con la tutela dell'ambiente.

Water quality problems have continuous increase around the world because of increased population growth and associated industrial activities. The presence of high levels of pollutants in natural water systems is of major concern because of their potential threats to both human and ecosystem health. Water resources in Kerala have been under increasing threat of pollution in recent years. This is due to inappropriate planning of human settlements that lack suitable sanitary infrastructure, as well as other human activities, including farming activities located very close to water bodies. Studies showed that Vattakkayal is heavily polluted. Vattakkayal hosts a number of freshwater fish species. If the quantum of pollution status of the lake persists like this or increases, the quality of water, fishes and other biota of the lake will get deteriorated to a greater magnitude, becoming a serious threat to mankind. The depletion and declining trend of fish population will adversely affect the fishery economy as it has commercial value and inturn will affect the local fisherman community being their major livelihood.
