M.Sc. Graduate Research Assistantships (6 positions) Aquaculture/Fisheries Center University of Arkansas at Pine Bluff
—–
1. Economics of Year-Round Production of Hybrid Striped Bass
Fingerlings

Hybrid striped bass growers would benefit from year-round availability
of the appropriate size of hybrid striped bass fingerlings. Indoor tank
systems have been used to raise hybrid striped bass fingerlings, but the
costs and risks have not been evaluated nor compared to pond production
costs and risks. The graduate student would work with hybrid striped
bass growers and researchers at the Stuttgart National Aquaculture
Research Station to assemble a database from which costs and returns
would be estimated related to production of hybrid striped bass in ponds
and tanks. Mixed integer mathematical programming models of hybrid
striped bass fingerling production will be developed to assess the
farm-level trade-offs associated with alternative technologies to
produce hybrid striped bass fingerlings year-round.

Admission requires a B.S. degree in aquaculture, fisheries,
agricultural economics, or a related field, a minimum GPA (last 2 years)
of 3.0 and GRE score of 1,000 (verbal + quantitative). Applications
will be considered until a candidate is selected (proposed starting date
August 1, 2008).

2. Optimal Feeding Strategies of Channel Catfish for Cool Weather
Feeding

Description: While a number of winter feeding studies have been
conducted on channel catfish over the years, there is a clear lack of
understanding of the optimal feeding strategies for cool weather
feeding. The successful applicant for this position will prepare a
specific research proposal upon arriving on campus describing thesis
research in the area of catfish physiology. Specifically, the student
will examine winter feeding practices in channel catfish and gather data
that evaluate endocrine & metabolic responses to experimental
winter-feeding protocols and link these indices to production parameters
collected from catfish ponds. A mixture of laboratory and field
responsibilities will serve students with an interest to apply basic
biology principles in an applied aquaculture setting.

Qualifications: B.S. in aquaculture, fisheries, biology, or related
field, minimum GPA of 3.0, and GRE score of 1,000+ (verbal +
quantitative) are required for regular admission. Minimum TOEFL score of
550 for international students. Strong writing skills and computer
proficiency are required. Demonstrated experiences with maintenance of
animals/livestock, familiarity with aquaculture, analytical laboratory
experience, and basic plumbing and construction skills are all desirable
qualifications.

Stipend: (Year 1 $17,800; Year 2 $18,800).

Closing Date: Applications will be considered until a candidate is
selected.

3. Controlling Copepod Populations for Water Reuse

Freshwater supplies in the US have seen tremendous declines over the
last several decades. Consequently, water used for aquaculture purposes
will need to be reused in the near future. However, water reused in
ponds needs to be free of larval fish predators, intermediate disease
hosts, as well as disease organisms. Investigating methods to control
cyclopoid copepods, known larval fish predators, in water destined for
reuse is essential. Several aquaculture ponds throughout Arkansas will
be monitored over a production cycle to determine copepod population
cycles. Toxicity tests to several compounds will be tested to determine
methods of control.

Responsibilities: The successful applicant will conduct her/his M.S.
degree research on cyclopoid copepod population dynamics and the
toxicity of various chemicals to them.

Qualifications: B.S. in aquaculture, fisheries, or related field,
minimum GPA of 3.0, and GRE score of 1,000+ (verbal + quantitative).
Minimum TOEFL score of 500 for international students. The student needs
to enjoy the combination of field and laboratory work.

Salary: Year 1 $17,800; Year 2 $18,800.

Closing Date: Applications will be considered until a candidate is
selected.

4. Development of Mathematical Models of Catfish Production
Characteristics

Channel catfish, Ictalurus punctatus, composes the major portion of
aquaculture in the United States. Pond production research studies have
evaluated the effects of stocking density, size at stocking, and various
feeding and cropping systems on growth, yield, and costs. The students
selected for this assistantship will combine data from these studies in
a meta-analysis to develop comprehensive mathematical models of catfish
production.

Qualifications: B.S. degree in aquaculture, fisheries or a related
field, a minimum GPA (last 2 years) of 3.0 and GRE score of 1,000
(verbal + quantitative). The student needs to enjoy the combination of
field and laboratory work

Stipend: $17,800 first year, $18,800 second year

Deadline: Open until candidate is found.

application forms ( www.uaex.edu/aqfi/ ) and send to:

5. Characterization of Fish Holding Shed Water Quantity and Quality

Aquaculture pond effluents have been characterized, but only
preliminary data are available on the characteristics of effluents from
holding sheds. Shed effluent characterization is particularly
challenging in that effluent quality and volume vary greatly over time.
For example, minnows typically are harvested during the week, hardened
and graded, and held prior to transport to retail outlets targeting
weekend sales. Vats are flushed after newly harvested fish are unloaded
and then daily, typically in the morning. Fish loading rates will vary
with sales and will change seasonally, as will on-farm hauling tank
water quality, the water that is discharged together with harvested
fish, into the holding vats. Holding shed effluent characteristics will
be monitored quarterly over a year (winter (Jan-Feb); siring
(April-May); summer (July-Aug); and fall (Oct- Nov)).

Responsibilities: The successful applicant will conduct his/her M.S.
degree research on fish holding shed discharge water quality and
quantity.

Closing Date: Applications will be considered until a candidate is
selected.

6. Using National Retail Databases to Determine Market Trends for
Aquaculture Products from the Southern Region of USA

Description: Retailers are becoming dominant players in the seafood
chain in the US and are providing their customers with an array of
seafood products-fresh fish, frozen processed products and canned food.
National scanner data provide a key opportunity and resource to
understand current trends in the retail markets, and to analyze consumer
preferences and diversified demand structures. Use of these data has the
potential to lead to the design of production and marketing strategies
that match market trends and consumer preferences. The student selected
for this assistantship will use store scanner data to analyze market
trends and retail pricing issues (e.g., retailers pricing behavior,
market competition) for catfish, crawfish, clam, and shrimp, and will
use household-based scanner data to analyze consumer behavior.

Qualifications: Admission requires a B.S. degree in aquaculture,
fisheries, agricultural economics, or a related field, a minimum GPA
(last 2 years) of 3.0 and GRE score of 1,000 (verbal + quantitative).
Minimum TOEFL score of 550 (paper based) or equivalent for international
students. Strong quantitative (statistics, mathematics) skills and
computer proficiency are required. Demonstrated experience with
maintenance of large data set is a desirable qualification.

Stipend: (Year 1 $17,800; Year 2 $18,800).

Closing Date: Applications will be considered until a candidate is
selected (proposed starting date August 1, 2009).

To apply, complete graduate application materials and assistantship
application forms (www.uaex.edu/aqfi) and send to:
