Book (stand-alone)Improving feed conversion ratio and its impact on reducing greenhouse gas emissions in aquaculture 2017
Also available in:
No results found.The study (workshop presentations, proceedings, GHG tool and recommendations) was carried out to improve FCR and asses its impact on reducing GHG emissions in Aquaculture. Three major objectives of this study was to assess the current GHG contributions of aquaculture and ways to measure it, ii) explore the potential to continue reducing FCR in salmon farming and other species, and therefore improving their environmental performance including GHG and iii) explore potential transfer of feed and fe eding technologies and lessons learn from salmon farming to other freshwater species such as tilapia, carps and catfishes and marine shrimp. The findings of this study identified several factors that affect FCRs, particularly in species farmed in developing countries, which could be targeted with programs that ultimately would reduce GHG and other emissions. The study concluded that managing environmental aspects, simplifying farm management, and improving feed management, would improve FCRs and reduce GHG emissions. -
MeetingAsia-Pacific Fishery Commission (APFIC) Regional Overview of the Status and Trends of Aquaculture in the Asia-Pacific Region 2016 2017
Also available in:
No results found.The aquaculture production in the Asia-Pacific Region during the two year period (2012-2014) is reviewed to see how the aquaculture sector in the region performed during these 2 years. This will allow for the determination of the driving factors that are responsible of the over-all performance of the aquaculture sector. Country production data from the FAO database is the main source of the production statistics used. The over-all performance of the aquaculture sector in the region remained healthy and strong. The region remains the largest contributor to the global supply of fishery products from aquaculture farms supplying 91% of the total global supply of aquaculture products in 2014. As in the previous years, China remained the largest producing country of aquaculture products contributing 63.7 % of the total production in the region, and 58 % to the global supply. Indonesia is fast catching up with its 2014 production up by almost 50% compared to 2012. Other countries that posted modest increase in their aquaculture production between 2012 and 2104 include India (15.9%), Bangladesh (13.4%), Viet Nam (10.2%), New Zealand (9.7%) and Myanmar (8.5%). Although the volume of the production is not much and the production data are all FAO estimates, it is noteworthy to mention that the aquaculture production of Cambodia increased by 62.2% during the 2-year period. Thailand posted the largest decline (26.5%) in its production during 2012 and 2014 largely due to more than 50% decrease in the production of the white leg shrimp as it is affected by a major disease specifically the Acute Hepatopancreatic Necrosis Disease (AHPND or popularly called Early Mortality Syndrome or EMS). The aquaculture production in Malaysia, Philippines and Australia decreased as well by 17.9, 8.7 and 8.4%, respectively. The herbivorous and omnivorous freshwater (FW) fishes like the carps remained the top commodity for culture with production volume in 2014 equivalent to 41.6% of the total fish production in the region. This has increased by 10.7 % over the 2 year period. Aside from the carps, other FW fishes like the tilapias, catfishes and the FW fishes nei also posted significant increase in production. In addition, the seaweeds particularly Eucheuma in Indonesia and Japanese kelp and Gracilaria in the China sub-region showed more than 30% increase in production between 2012 and 2014. On the other hand, the production of white leg shrimp in Thailand and giant tiger prawn in Indonesia suffered significant decline of more than 30% during the 2-year period. It must be noted, however, that white leg shrimp production in other countries like in India and Indonesia remained strong with increase in annual production of more than 50%. Some important issues like the need to prevent outbreaks of diseases in aquaculture farms, the awareness and the commitment among the players to ensure the good health of the surrounding environment where the aquaculture activities are happening, the need to ensure the sustainability of the use of pelleted feeds, and the necessary preparations that have to be put in place for the future warmer climate have to be consistently in the radar screen to ensure the sustainability and the continued growth of the sector, and thereby for humanity to continue reaping the benefits that can be derived from the industry. -
Book (stand-alone)Greenhouse gas emissions from pig and chicken supply chains – A global life cycle assessment
A global life cycle assessment
2013Also available in:
No results found.The livestock sector is one of the fastest growing subsectors of the agricultural economy, and faces several unprecedented and concomitant challenges. The sector needs to respond to the increasing demands for livestock products that are arising from population growth and changing consumer preferences. It also has to adapt to changes in the economic and policy contexts, and in the natural environment upon which production depends. At the same time, it has to improve its environmental performanc e and mitigate its impact on climate. The pig sector is the biggest contributor to global meat production, with 37 percent in 2010. Chicken meat accounts for about 24 percent. Global demand for pig meat, chicken meat and chicken eggs are forecast to grow by 32 percent, 61 percent and 39 percent respectively during the period 2005-2030. If the greenhouse gases (GHG) emissions intensities (emission intensity; or the kg of GHG per kg of product) of these commodities are not reduced, the increa ses in production required to meet demand will lead to proportionate increases in GHG emissions. Improving our understanding of where and why emissions arise in livestock supply chains is an important step towards identifying ways to improve efficiency and reduce emissions intensity. This report presents a life cycle assessment (LCA) of the GHG emissions arising from pig and chicken supply chains. It provides a detailed analysis of emissions according to region, sector and systems of product ion. In addition to informing efforts to reduce GHG emissions, it is hoped that the assessment will also help inform public debate on this important subject.
