“…This is in accordance with the literature data (Shearer 1984, Deegan 1986, Torres & Vanni 2007, which shows that phosphorus varies in a fish's body from early to later stages of growth. In our previous study (Hlaváč et al 2016), we found that carp body phosphorus and nitrogen content varied from early to later stages of growth, with a noticeable increase in dry matter content during the growing season. Additionally, diet also has an influence on the chemical composition of fish, e.g.…”

Appropriate supplementary feeding is of increasing importance in common carpCyprinus carpio pond aquaculture, not only with respect to production issues but also as a sustainable tool for maintaining environmental quality. We studied the effect of different supplementary feeding regimes (no supplemental feed, cereal grains, pelleted feed, pelleted feed with lowered phosphorus content, and extruded feed) on growth performance, water quality, natural food availability, phosphorus budget, fish body composition and economic performance in 10 experimental ponds stocked with 3 yr old carp at a density of 363 fish ha −1 over a 4 mo period. The type of supplementary feed had no significant influence on water variables, with the exception of lowphosphorus pelleted feed which increased conductivity (p < 0.05). No significant differences were observed in zooplankton density. Harvested fish had significantly (p < 0.05) higher dry matter content and considerably higher phosphorus content under all treatments compared with fish at the beginning of the experiment. The use of cereals and extruded feed improved carp growth, while the physical qualities of the feed (higher resistance to nutrient leaching) resulted in lower nutrient concentrations in effluent water. Profitability was increased with application of cereal grains and decreased with all pelleted and extruded feeds. Hence, the use of cereal grain feed generated higher economic and environmental benefits than selected pelleted and extruded feed.

“…Furthermore, as stagnant ponds can be characterized with relatively quick nutrient mineralization and turnover rate, enhancing natural processes removing natural pollutants, like phosphorus from water [29], such environmental factors may also contribute to the lack of significant differences in water quality between the different feed types in our experiment. It should also be noted that the different diets may not always alter water quality parameters substantially [30], but in certain cases, differences in organic matter and chlorophyll-a [31] or conductivity [32] were reported in similar experiments.…”

Semi-intensive common carp (Cyprinus carpio) farm technology uses several feed types affecting the growth performance; however, we know less about their long-term effects on water quality. Herein, we evaluated the effects of three commonly used feeds—moderate levels of fish meal and fish oil feed (FF), plant meal and plant oil feed (PF), and cereal feed (CF) on the nutrient (total nitrogen (TN), total phosphorus (TP) and organic matter (OM)) content of the pond water. The experiment was carried out over three consecutive years from juveniles to market-sized fish. The type of feed affected the net yields, but generally, it did not affect the water quality. The year of sampling, however, was a significant factor affecting TN, TP, and OM, whose concentrations decreased during the three years. Our findings highlight that the age of the stocked fish on water quality has a more pronounced effect than the nutrient profile of the supplementary feed. Additionally, the plant-based feed could provide comparable net yields as the fish meal-based feed without additional nutrient loading in the water column, reinforcing the sustainability of alternative feeds in semi-intensive carp farming.

“…Furthermore, the use of pelleted or extruded feeds enhances digestibility, minimizes water pollution, and promotes better fish growth. Applying thermal and mechanical treatments to supplementary feeds prior to their use in aquaculture ponds can help reduce undigested or poorly digested feed, further improving efficiency and decreasing environmental impacts [115,116].…”

Legislation and interest exists to protect and restore freshwater and marine ecosystems from the environmental impact of aquaculture. However, aquaculture-induced eutrophication remains a major environmental concern. Water soluble phosphorus, uneaten feed, feces, and metabolic waste from farmed fish increase phosphorus concentrations in adjacent waters. In open freshwater fish farms, in particular, the effects can be more immediate, as excess phosphorus is introduced directly into ecosystems. Several intestinal enzymes, transporters, and regulating factors have been implicated in farmed fish dietary phosphorus retention. For example, alkaline phosphatase and other transporters aid in the absorption of phosphorus in the anterior intestine, while pH, calcium, and vitamin D influence these enzymes and transporters. This process may also be influenced by intestinal morphology and the gut microbiome. To reduce phosphorus pollution from open flow fish farms, a thorough understanding of the processes that affect nutrient retention and absorption, as well as the impact of dietary factors, anti-nutritional substances, and intestinal morphology, is required. Aquaculture can be made more sustainable by reducing phosphorus release. This can be achieved by optimizing feed composition, adding functional feed ingredients, managing gut health, and treating effluent aquaculture waters with bioremediation and absorbing materials. Anti-nutritional factors can be mitigated through processing and through the use of functional feed additives. Addressing these issues will reduce aquaculture’s environmental impact, ensuring aquatic ecosystem health and global food security. In addition, treating effluent aquaculture waters with bioremediation and absorbing materials can remove phosphorus from the water, preventing it from entering the environment. This can further reduce the environmental impact of aquaculture and help to ensure the sustainability of this sector.
