Lopez has deep professional and academic roots in the PD/A CRSP. He has been
actively involved in the CRSP for the past ten years and has played numerous
roles. He initially worked on the Fish Pond Fertilization Trials Project in
the Philippines as a host country Principal Investigator from 1991 to 1996
with Kevin Hopkins of the University of Hawaii and Jim Szyper of the Hawaii
Institute of Marine Biology. Lopez also served as a member of the PD/A CRSP
Technical Committee during his tenure as a principal investigator. One can
quickly pick up, through his increasing amount of responsibilities, that Lopez
is a motivated individual and has been a key participant in CRSP activities
in the Philippines. As a result of Lopez’s hard work with the PD/A CRSP,
he has received funding that has supported his advancement through graduate
school.

Recently, Lopez has been building on his strong academic
foundation while working with the PD/A CRSP. He obtained a B.S. in Agriculture
with a major in inland fisheries at Central Luzon State University (CLSU),
a Masters of Aquaculture at Auburn University, and an M.S. in aquaculture
also at CLSU. Currently, Lopez is an Associate Professor and researcher at
the Freshwater Aquaculture Center at Central Luzon State University and is
pursuing his Ph.D. in Fisheries at the University of the Philippines in the
Visayas (UPV).
After five years of hard work, Lopez is concluding his
Ph.D. He has completed all of the required coursework, data collection, and
data analysis and is now in the process of writing the manuscript in consultation
with his dissertation adviser Crispino Saclauso, Professor at UPV. He plans
to present his dissertation by December 2001. The Philippine Council for Aquatic
Marine Resources Development (PCAMRD) has provided funding for Lopez’s
Ph.D. work, and additional financial dissertation support has come from the
PD/A CRSP through the initiative of Chris Brown at Florida International University
(FIU). FIU is the lead US university for the CRSP Philippines Project and
holds a memorandum of understanding with CLSU.
Lopez’s multifaceted dissertation is titled, “Interaction
of growth, survival and social behavior of Genetically Manipulated Tilapia
(GMT) (Nile tilapia–Oreochromis niloticus).” The project
contains both descriptive and experimental components. The descriptive component
includes analyzing motor and color patterns in GMT tilapia fingerlings and
adults; observing feeding behavior of GMT tilapia with respect to food abundance
and distribution; and evaluating fertilized egg size distribution. The experimental
component comprises rearing GMT larvae to fingerlings at three stocking densities;
analyzing social hierarchy and its effects on the growth and survival of dominant
and subordinate conspecifics of GMT tilapia population; observing social hierarchy
and compensatory growth in different size classes of GMT tilapia population;
and exploring growth, survival, and social behavior of GMT fish as affected
by space heterogeneity.
Lopez’s motivation is demonstrated through his current,
active involvement in research, teaching, and extension. The PD/A CRSP has
been fortunate to have Lopez active in the CRSP for the past ten years and
hopes that this relationship will continue as he earns his Ph.D. and continues
to work in the aquaculture field.
