Influence of fish cage farming on water quality and plankton in …
2011年6月15日 · Our study examines whether small-scale cage fish farming has a potential influence on the water quality and plankton composition in reservoirs and ponds that may be attributed to intensive inputs. Moreover, we provide useful information for further planning in aquaculture development.
Effects of bivalve aquaculture on plankton and benthic community
2024年3月1日 · The expansion of bivalve aquaculture may adversely affect plankton and benthic food webs by modifying phytoplankton community structure, increasing the sedimentation rate of fine suspended particles and promoting vertical flow of nutrients to the benthic environment.
Comparison of water quality, planktonic community, and volatile …
VOCs related to plankton interactions and flavor were identified firstly in fish cages. Five fish cage farming areas had different plankton community and VOCs. Plankton community and VOCs correlated with water and fish quality. Water quality correlated with …
Spatial and temporal dynamics of phytoplankton in association …
2021年5月6日 · However, significantly high plankton density indicating a polluted status at the cage site reveals the influence of cage culture. Phytoplankton, the primary producers in an aquatic ecosystem, also act as indicators of pollution by alterations in …
Marine cage culture and the environment: Effects on water quality …
2015年2月4日 · Increasing human population and reliance on aquaculture for seafood will lead to expansion of the industry in the open ocean. To guide environmentally sustainable expansion, coastal stakeholders...
(PDF) Impact of fish cage-culture on the community structure of ...
2011年6月30日 · We investigated the impact of fish cage culture on the zooplankton community structure in a tropical reservoir. We hypothesized that community abundance is greater near cages and increases over...
Influence of fish cage farming on water quality and plankton in …
2011年6月15日 · Phytoplankton community structure and how it is influenced by commercial tilapia cage farming in three tropical lakes in eastern Brazil is examined, showing fish farming clearly influences water quality as measured by algae species richness and abundance but is also moderated by the unique conditions in each lake.
Plankton Diversity and Dominance in Three Undrainable
2021年3月13日 · The present study focuses on variation in plankton abundance according to zero-fed, bag-fed and integrated cage cum pond aquaculture system. The results indicate the plankton abundance increases if the system is managed and optimum inputs are supplied.
Cage culture: site selection and water quality | The Fish Site
2007年9月21日 · Most fish kills, disease outbreaks, and poor growth in cage situations are directly or indirectly due to low dissolved oxygen. Turnovers and plankton die-offs are two other situations in which dissolved oxygen levels may fall below critical levels. Turnovers occur during cold rains, heavy winds, and prolonged cold spells in summer.
Effects of a small fish cage farm on zooplankton assemblages ...
Higher algal biomass, concentration of low-oxygen/pollution-tolerant macro-benthos and depressed zooplankton diversity at WC suggested impacts from the fish cages on aquatic biota.
