Aquaculture

Biophysical impacts of aquaculture, with consequences for biodiversity, vary with species and culture systems and include issues such as: nutrient enrichment/removal, chemicals, land use, species introductions, genetic flow to wild populations, disturbance of balance or introduction of pathogen/parasites, consumption of capture fishery resources, energy, and greenhouse gas emissions. Guiding principles, labeling schemes and various tools are needed to analyze performance and conformance. Ecological footprints and…

Indonesian aquaculture futures – Evaluating environmental and socioeconomic potentials and limitations

Indonesia is the world’s second largest seafood producer, but capture fisheries landings have stagnated over the last decade. In response, the Indonesian government has set ambitious targets for expanding the aquaculture sector up to 2030. The present research therefore quantifies environmental impacts using life cycle assessments (LCAs), and some socioeconomic indicators, for six alternative scenarios projecting the growth of Indonesia’s aquaculture up to 2030 by…

Environmental impact of non-certified versus certified (ASC) intensive Pangasius aquaculture in Vietnam, a comparison based on a statistically supported LCA

Pangasius production in Vietnam is widely known as a success story in aquaculture, the fastest growing global food system because of its tremendous expansion by volume, value and the number of interna- tional markets to which Pangasius has been exported in recent years. While certification schemes are becoming significant features of international fish trade and marketing, an increasing number of Pan- gasius producers have followed…

Use of Wastewater from Striped Catfish (Pangasianodon hypophthalmus) Pond Culture for Integrated Rice–Fish–Vegetable Farming Systems in the Mekong Delta, Vietnam

This article investigates the feasibility of reusing wastewater from striped catfish (Pangasianodon hypophthalmus) pond culture as nutrient input for integrated rice–Nile tilapia–green bean farm- ing systems, and to what extent this could contribute to decreasing the environmental impacts on water quality from the striped cat- fish industry in the Mekong Delta. Four treatments in triplicates were used to investigate the growth of rice and green…
