Marine Environmental Management and Development Strategy for Marine Aquaculture in Taiwan: Cobia Case Study

“…Marine aquaculture may also cause environmental degradation from feces, uneaten feed and use of chemicals if the local carrying capacity is exceeded [5,6]. Marine aquaculture of finfish has become increasingly intensive in recent decades, primarily due to the introductions of new technologies, the expansion of suitable sites, improvements in feed technology, an improved understanding of the biology of the farmed species, improved water quality within farming systems, and an increased demand for fish products [7][8][9]. Such intensive development of the industry is now widely understood to have had a severe impact on the environment [10].…”

Established the Environmental Monitoring Program Indicators to Prevent Disease Infection and Promote Sustainable Development

“…Finfish farms need more extensive programs for the management of waste than shellfish farms, because finfish provide exogenous food sources [10]. Redox potential is useful as an indicator of the degree of microbial activity in organically-enriched sediments [13,14]. Here we used an EMP to determine and assess the environmental impact of farming.…”

Integrated assessment of sustainable marine cage culture through system dynamics modeling

“…However, poorly flushed and shallow areas with long water-residence times are more susceptible to eutrophication and algal blooms, leading to cultured-fish kills (Baula et al, 2011;San Diego-McGlone et al, 2008). In addition, over-expansion of cage farming, high stocking density, and poor environmental management also tend to decrease the survival rates of cultured fish (Shih et al, 2009 Therefore, incorporating the local hydrodynamic regimes of the farming site into fishery management systems may help reduce environmental risks and lead to more well-informed decisionmaking.…”

“…In Taiwan, the authorities (Fisheries Agency of the Council of Agriculture) have largely encouraged the development of modern marine cage culture with the predominant cultivation of cobia (Rachycentron canadum) and groupers in Penghu Archipelago in the early 1990s (Chen and Hsu, 2006;Liao et al, 2004). Recently, marine cage culture has been recognized as the main pollution source in the coastal area because of minimal environmental quality criteria and management guidelines Shih et al, 2009). In Magong Bay, nutrient and organic enrichment have been observed in the surrounding environment and have varied mainly in response to the seasonal movement of water driven by local climatic occurrences (Huang et al, 2012a,b).…”
