“…For instance, the role of this polyculture in sustaining the local population economically has been investigated, showing a benefit for poor people (Irz et al, 2007). In our study, human labour is considered more an input to the production system.…”

Environmental performance of brackish water polyculture system from a life cycle perspective: A Filipino case study

Life Cycle Assessment (LCA) was applied to assess the environmental performance of brackish water polyculture of black tiger prawn, mud crabs, tilapia and milkfish in a pond aquaculture system. The study was conducted on 15 production sites, located in Pampanga Province of the Philippines. The scope of analysis covered the hatchery or capture of juveniles from the wild up to the delivery of products to auction markets. Impact categories included eutrophication, acidification, climate change, land occupation, net primary production use, total cumulative energy demand (TCED), and total human labour. Life cycle impact indicators were calculated for one tonne of product (total production or that of individual species) using both energy-based and economic allocations. The results indicated that the main impacts from farming operations were eutrophication, land occupation, acidification and human labour. Feed (molluscs harvested from aquatic ecosystems) mainly influenced net primary production use, TCED and climate change, and harvesting and delivery mainly influenced climate change and TCED. Differences in farm practices and yields induced high variability in impacts. Production site size had no significant effect; however, its distance from the sea appeared to affect its efficiency and, consequently, impacts. Changing the allocation method changed the ranking of species' impacts within each impact category, milkfish having the highest impacts with energy-based allocation and prawn and crabs having the highest impacts with economic allocation. The lack of differences in impacts between intensive monocultures of prawn and tilapia recorded in the literature and the same species in Pampanga's polyculture suggests that the degree of intensification is not a relevant concept for distinguishing impacts of aquaculture systems.

“…sustainably, rural aquaculture can boost total farm food production and income and can provide farm families an additional protein source (Irz et al 2007). In [2008][2009], our research team began to explore the potential for smallholder black tiger shrimp Penaeus monodon farming to provide rural economic benefits in Sri Lanka.…”

Black tiger shrimp Penaeus monodon farming is important for Sri Lanka's rural development plans. Consumer confidence is critical for the development and maintenance of export and domestic shrimp markets. Public concern about the use of antimicrobial drugs and chemicals on shrimp farms, however, could threaten market access. We sought to identify high-risk areas and farm-level risk factors for antimicrobial use to inform the core messages and strategic placement of extension programs to help farmers develop best management practices for antimicrobial use. We undertook a survey of 603 operating farms within the Puttalam district over 42 weeks. Lower stocking density and early harvest were associated with a lower risk of antimicrobial use, whereas standard management practices, including water treatment, feed supplements, probiotic use, pond fertilizing, disinfectant use, and pesticide use, were associated with increased risk. Spatial cluster detection found three significant clusters of antimicrobial-using farms. Antimicrobials were more likely to be used in areas with lower farm density. Some of our counterintuitive findings are discussed from a socioecological perspective. A comprehensive understanding of why antimicrobials are used on shrimp farms requires an evaluation of the physical, epidemiological, and socioeconomic factors.

“…Even when aquaculture activities do not return the same economic benefit per unit effort as fishing, aquaculture job demands differ fundamentally from fishing and seasonal (self‐)employment, thereby creating distinct advantages (Irz et al ). Aquaculture jobs offer a certainty of location, which allows fish farmers to make choices about family position and housing that improve household stability.…”
