Challenges in the project (both former and in the future):

Failure on getting scientific equipment on ocean acidification changed the original plan, moving the wet lab made a delay on PhD student’s research.

 

Progression plan for finishing the project:

Comments on the supervision:

Demonstrating flexible capacity, awareness on adjusting research plan adapting with new situation. Encourage, support student to complete research and publication plans. High responsibility.

Comments on administrative support: sufficient

 

Any other  issues affecting the project

Lack of realities on possibility of establishing ocean acidification facilities in NTU, insufficient connection between UiB and NTU on project proposal preparation.

     

 

 
II. Economic component 

Project title: Macro and Micro-level impacts of climate change on Vietnamese aquaculture: A case study in central and southern parts of Vietnam

Project objective:

My Phd project concentrates on

  • Economic efficiency of shrimp farming under climate change

•       Income source and household livelihood strategies of aquaculture household under the impact of natural disasters

•       Shrimp farming households’ perceptions and risk attitudes regarding climate change

Specific objective:

  • First paper aims to estimate shrimp farming inefficiency under the influence of variables related to climatic events, farming characteristics and socio economic factors, which shrimp production system are appropriate to cope to climatic events (drought, saltwater intrusion, irregular season)
  • Second paper tries to assess the income source, expenditure change, poverty status and household livelihood strategies for resilience capacity of aquaculture household under the impact of natural disasters in Vietnam.
  • Third paper highlights shrimp farming households’ perceptions and risk attitudes regarding climate change in the Mekong Delta, Vietnam by identifying determinants that affect shrimp farmer’s choice of adaptation measures to climate events. The adaptation methods applied to restrict the impact of climatic events focus on 5 types, namely changes in farming practices, changes in farm infrastructure, shifts to other occupations, and received support and others adaptive measures

Contents:

III. Aquaculture Component

Project title: Effect of elevated temperature and feeding frequency on clownfish Amphiprion ocellaris

Project objective: To get an insight to the effect of global thermal rise on feed intake, appetite, growth, survival rate and welfare of the fish to determine their thermal tolerance

Specific objective: In this study, fish are cultured in different temperature and feeding frequency. Then, feed intake, oxygen consumption, growth and survival rate will be determined to understand how the metabolic rate, energy demand, growth, survivorship and the energy trade-off of the fish at early stages correspond to the thermal stress under limited availability of  food.

In addition, the relation between feed intake and the changes of appetite controled hormone (located in fish brain) levels when fish are acclimated to different temperatures will be studied. Results from this observation will be useful for understanding the consequences  of global warming effect on coral reef fish welfare.

Contents:

-          Effect of elevated temperature and feeding frequency on growth, feed intake and appetite of Amphiprion ocellaris juvenile.

-          The metabolic rate and appetite of Amphiprion ocellaris in response to different temperature expossured profiles at larval stage.

-          Effect of different thermal regimes on growth performance, metabolic rate and appetite of Amphiprion ocellaris juveniles.

Methods: Details for methods have already presented in the approved research proposal.

Time schedule: 2015-2018

Output:

-          01 Research proposal (done)

-          03 Annual report and final report (in progress)

-          At least 01 paper will participate in the international conference (done)

-          At least 01 paper will be published in national journal (in progress)

-          At least 02 paper will be published in ISI journal (in progress)
