Life Cycle Analysis ( Lca )
Introduction to Life Cycle Analysis Life cycle analysis (LCA) provides a systematic
evaluation of a system/industry to improve through implementing more efficient and
ecological design and developmental techniques, ecological and social positive
development, eliminating wastes, decreasing deleterious inputs and outputs, and
pollution prevention as well as reevaluating ethical and social impacts afflicted
through practices.
Taking a less harm approach is often the first step in evaluating the impact of a
product s life cycle on the environment beginning from the abstraction of raw
materials, manufacturing, production, consumption, and ending with
dematerialization. Although, no one tool is adequate to the task of measuring ... Show

Through the farming process, natural occurrences such as competition for food
resources, predation, diseases, climate change, and reproduction are manipulated. The
farming environment is controlled and regulated using various techniques dependent
on the species, either fish, crustaceans, aquatic plants, and mollusks. Aquaculture
involves the propagation, cultivation, and marketing of these aquatic stocks (Swann
1992) and can also include ownership, individual or corporate, of production stocks
(Goldburg et al. 2001). Within the aquaculture industry there are several categories of
aquaculture facilities including but not limited to concrete ponds, trays and longlines
(Goldburg et al. 2001), tank systems, Earthen ponds, net pens, cages, raceways, and
recirculating systems (RamГ rez GodГ nez et al. 2013). The production systems of
these facilities range from traditional, low intensity sustenance to highly intensive
production in man made earthen pools, freshwater, brackish, and marine
environments (Pelletier and Tyedmers 2008).
The North American Industry Classification System (NAICS) categorizes fauna
aquaculture establishments as follows:
Finfish farming and fish hatcheries (NAICS code 112511), which finfish production

auratus auratus), tropical
