Potential applications of biological filtration media in changing water properties and subsequent effects on common carp (Cyprinus carpio) in recirculating aquaculture systems

Abstract

According to the FAO (2016), water demand will increase roughly by 50% in 2030 due to rising global population, global warming and drought. The growth of aquaculture is critical to ensure a sufficient supply of food to meet the growing demand of the world's population. However, this also means that feed supply must also increase to keep up with the production of fish (FAO, 2014). High water quality refers to the quality of water that ensures the successful culturing of organisms, including fish, shellfish, crustacean and others. The maintenance of high-quality water is important for the survival and maximum growth performance of cultured species (Datta, 2012). Water quality is defined by parameters that include ammonia concentration and suspended organic material (Carbajal-Hernandez et al., 2013). Intensive fish culturing requires the removal of harmful fish metabolic products, such as

Ocean Deacidification Technologies for Marine Aquaculture

“…In a TF, water is pumped to the top of the filter, where gravity pulls the water down through the filter medium (Figure 3) [53]. The medium can be unstructured/structured polyethylene [54], wood wool/sawdust [55], constructed wetland [56], or other materials that break up the flow of water. Aeration of the water in 5 of 12 combination with an air stream in the direction opposite to the flow of water (caused by a fan) allows CO 2 to diffuse from the water to the surrounding air.…”

Replacing starch with resistant starch (Laminaria japonica) improves water quality, nitrogen and phosphorus budget and microbial community in hybrid snakehead (Channa maculata ♀ × Channa argus ♂)

“…Furthermore, intensive aquaculture farming is commonly used to boost aquaculture productivity (Santos & Ramos, 2018). Food residues and manure residues are abundant in high‐intensity feed feeding and high‐density farming, leading to the build‐up of overloaded nitrogen and phosphorus in the aquatic environment (Hassan et al, 2021; Yarahmadi et al, 2015). This can have negative consequences for the environment, such as eutrophication‐induced algae blooms and faecal‐breeding bacteria (Jung et al, 2017).…”

Utilization of the Different Vegetables as a Filtration plants on Water Quality, Growth Performance, Plasma Biochemistry and Histopathology of Common carp (Cyprinus carpio) in Incorporated Aquaponics System

“…Within closed aquaculture systems, meticulous water quality management is of paramount signi cance, exerting a profound in uence on sh comfort, growth, and yield (Waltham et al, 2019). The fabric of this investigation is woven through a meticulous exploration of diverse vegetable species, their capacity to serve as e cacious bio lters, and their intricate in uence on the growth and vitality of Common carp (Roalkvam et al, 2020;Hassan et al, 2021). Through this synthesis of knowledge, this study seeks to propel the horizons of aquaponics technology, thereby nurturing a blueprint for the advancement of sustainable and resource-e cient aquaculture practices (Fossmark et al, 2020).…”
