2. Explanation of the methods and techniques used to sample aquatic macroinvertebrates in the polyculture fishponds.
Several approaches and techniques were used to sample and evaluate the composition of aquatic macroinvertebrate species in the investigation of their abundance in French experimental polyculture fishponds. Using standardized sampling methods including kick-sampling and dip-netting, macroinvertebrate samples were taken. Kick-sampling is the process of uprooting macroinvertebrates from the pond's substrate so that they can be gathered downstream with a hand net. Benthic creatures that live on the substrate can be successfully captured with this technique.
In contrast, dip-netting is skimming a fine-mesh net through the water column in order to collect any macroinvertebrates that are swimming or floating. Kick-sampling alone might not be able to capture certain pelagic or open-water species, but this technique can help. Both techniques were used in the fishponds at various points to guarantee representative sampling in a variety of habitats and microenvironments.
Environmental DNA (eDNA) analysis was used to supplement conventional ways of assessing aquatic macroinvertebrate ecosystems in addition to direct sample procedures. By removing genetic material that organisms excrete into their surroundings, eDNA offers a non-invasive way to identify and find species that are present in fishponds. Without physically capturing individual organisms, researchers were able to learn more about the diversity and spatial distribution of macroinvertebrates by examining eDNA samples from various locations inside the ponds.
In order to evaluate their possible impact on community composition, environmental factors including pH, water temperature, dissolved oxygen levels, and habitat parameters were assessed in tandem with macroinvertebrate sampling. This all-encompassing method assisted in establishing relationships between the abundance of macroinvertebrates in the polyculture fishponds and environmental conditions.
Through the use of advanced eDNA analysis in conjunction with conventional sampling techniques, researchers were able to compile a comprehensive picture of the aquatic macroinvertebrate populations in the French experimental polyculture fishponds. These techniques made it possible to conduct thorough evaluations of the links between the environment and community structure, which provided insightful information about the intricate dynamics of aquatic ecosystems in aquaculture settings.
3. Analysis of the relationship between aquatic macroinvertebrate abundance and the environmental conditions within the fishponds.
Understanding the dynamics of these ecosystems requires analyzing the relationship between the abundance of aquatic macroinvertebrates and the environmental parameters of the fishponds. Environmental elements that can have a major impact on the diversity and abundance of macroinvertebrates in aquatic environments include pH, dissolved oxygen levels, temperature of the water, and concentrations of nutrients. As a result, careful consideration of these variables is necessary for the management and preservation of fishpond ecosystems.
We carried out a thorough research in our investigation of French experimental polyculture fishponds to find out how environmental factors affect the quantity of aquatic macroinvertebrates. Our research showed that there was a significant relationship between the number of macroinvertebrates and some environmental factors, most notably the temperature of the water and the concentration of nutrients. We saw that the community structure of aquatic macroinvertebrates in the fishponds was significantly shaped by changes in pH and dissolved oxygen levels.
According to our investigation, some aquatic macroinvertebrate species exhibited preferences for various environmental circumstances. For instance, gammarid amphipods flourished in environments with comparatively lower pH levels, whereas some mayfly larvae were more prevalent in regions with higher dissolved oxygen levels. These results demonstrate the complex interactions that exist between the surrounding environment and the patterns of aquatic macroinvertebrate dispersion in polyculture fishponds.
Our study offers important insights for fisheries management and conservation initiatives by clarifying these links. By comprehending the ways in which environmental factors influence the diversity and quantity of aquatic macroinvertebrates, we may create more focused approaches to preserving the ecosystems of fishponds.

Researchers have discovered clear distinctions between the macroinvertebrate abundance in single-species aquaculture systems and polyculture fishponds. Compared to single-species aquaculture systems, polyculture fishponds often support higher levels of macroinvertebrates because of their varied variety of aquatic species. This is explained by the different biological niches that the polyculture ponds offer, which give the macroinvertebrate communities a more stable and balanced environment.
In contrast, because of their reduced variety and simpler ecosystem dynamics, single-species aquaculture systems frequently show lower levels of macroinvertebrate abundance. High stocking densities and consistent feeding schedules, two intensive management techniques used in these systems, may result in a reduction in the complexity of the habitat and the availability of resources for macroinvertebrates. Consequently, in single-species aquaculture settings, the overall number and diversity of these significant aquatic organisms are frequently reduced.
In polyculture fishponds, the presence of several fish species provides a greater variety of macroinvertebrate predation pressures, resulting in more intricate interactions and possibly affecting population dynamics. The balance of macroinvertebrate populations may be impacted by the lack of natural predation pressure diversity in single-species aquaculture ponds.
In contrast to conventional single-species aquaculture systems, the comparison emphasizes the potential advantages of polyculture fishponds in supporting higher levels of macroinvertebrate abundance. This emphasizes how crucial it is to take biodiversity and ecological dynamics into account when developing sustainable aquaculture methods that maintain the health of aquatic ecosystems.
