Title: Descriptions of AQUAFISH Project in China and South/Southeast Asia


1
Descriptions of AQUAFISH Project in China and
South/Southeast Asia
  • UM-SFU Team

2
  • Improving sustainability and reducing
    environmental impacts of aquaculture systems in
    China, and South and Southeast Asia

3
UM Team
  • James Diana University of Michigan, USA
  • Yang Yi, Jiang Min Liu Liping Shanghai
    Fisheries University, China
  • Wang Weimin - Huazhong Agricultural University,
    China
  • Le Thanh Hung University of Agriculture and
    Forest, Vietnam
  • Lai Qiuming Hainan University, China
  • Song Biyu Wuhan University, China
  • Madhav K. Shrestha Institute of Agriculture and
    Animal Sciences, Nepal
  • WWF

1. Impact of introduction of alien species on the
fisheries and biodiversity of indigenous species
in Zhanghe Reservoir of China and Tri An
Reservoir of Vietnam
  • Objectives
  • To investigate the changes in population
    structure of indigenous fish species after the
    introduction of alien species in the reservoirs
  • To compare reservoirs in China with and without
    presence of exotic icefish

5
1. Impact of introduction of alien species on the
fisheries and biodiversity of indigenous species
in Zhanghe Reservoir of China and Tri An
Reservoir of Vietnam
  • UAF
  • Collected secondary data
  • Started collecting primary data
  • HAU
  • Collected secondary data
  • Will start to collect primary data

2. Assessing effectiveness of current waste
management practices for intensive freshwater and
marine pond aquaculture in China
  • Objectives
  • To identify and quantify existing management
    practices to reduce effluent and solid waste
    pollution used by intensive freshwater and marine
    farmers
  • To quantify nutrient loading rates, nutrient
    budgets, sediment accumulation of nutrients, and
    release of nutrients in effluents for intensive
    ponds, utilizing different waste management
    strategies
  • To determine the best current methods for
    pollution mitigation in intensive pond
    aquaculture
  • To inform small-scale pond farmers about waste
    management in order to build a consensus on
    management and to develop more effective
    government policies.

2. Assessing effectiveness of current waste
management practices for intensive freshwater and
marine pond aquaculture in China
  • HAU
  • Completed survey of 120 carp farms
  • HNU
  • Completed survey of 100 shrimp farms
  • Completed survey of 100 tilapia farms
  • SFU
  • Selected Chinese Catfish farms

3. Determining the ecological footprint of shrimp
aquaculture through life cycle analysis of
outdoor pond systems
  • Objectives
  • Perform LCA and life cycle cost analysis (LCCA)
    for an outdoor, flushed pond shrimp aquaculture
    system.
  • Develop mass balance models of the shrimp
    aquaculture system to make it possible to
    evaluate methods to improve the economics and
    reduce the environmental impacts of the system.

3. Determining the ecological footprint of shrimp
aquaculture through life cycle analysis of
outdoor pond systems
  • An UM PhD student (Miss Cao Ling) is conducting
    the research in Hainan.

4. Monitoring and reducing microcystins in
tilapias and channel catfish cultured in a
variety of aquaculture systems
  • Objectives
  • Determine the content of microcystins in
    aquaculture ponds/tanks at different levels of
    intensification and different culture
    environments
  • Evaluate body burdens of microcystins in the
    flesh of tilapia and channel catfish cultured
    under different systems
  • Test possible depuration strategies to eliminate
    microcystins from the flesh of cultured tilapia
    and channel catfish.

11
4. Monitoring and reducing microcystins in
tilapias and channel catfish cultured in a
variety of aquaculture systems
  • Under planning.

12
5. Polyculture of sahar (Tor putitora) with
mixed-sex Nile tilapia (Oreochromis niloticus)
  • Objectives
  • To assess growth and production of Nile tilapia
    and sahar at different stocking ratios of sahar
  • To assess the appropriate stocking ratio of sahar
    to control recruitment of tilapia
  • To develop the appropriate tilapia-sahar
    polyculture system for farmers.

13
5. Polyculture of sahar (Tor putitora) with
mixed-sex Nile tilapia (Oreochromis niloticus)
  • On-station trial is conducted as schedule,
    starting on 14 Oct 2007.

6. Workshop on Aquaculture, Human Health and
Environment
  • Objectives
  • To present the research results of AquaFish CRSP
  • To share the experience in research related to
    aquaculture, human health and environment
  • To establish links between AquaqFish CRSP host
    institutions and other institutions in the
    region.

15
6. Workshop on Aquaculture, Human Health and
Environment
  • The workshop is scheduled to be held in August
    2009 at Chengdu, Sichuan province, China.
