Work Plan for a Study of the Feasibility of an Offshore Port Terminal in the Texas Gulf Coast Region. Dan M. Bragg and James R. Bradley. June 1971. 30 pages. TAMU-SG-71-212. NTIS-COM-71-00876.
Recent trends in ship sizes threaten to
make existing Texas ports obsolete, and there has developed a
growing need for a port with water depth adequate to handle larger
ships. A necessary prerequisite to constructing such a port is
the study of its physical and economic feasibility. The work plan
described here identifies individual studies required. Estimated
cost of these studies is $460,000, and total time required should
not exceed 18 months.
Port and Harbor Development System. Russell L. Stogsdill. November 1971. $4. TAMU-SG-71-216. NTIS-COM-72-10238.
Containerization, supersized vessels, ocean-going
barges and new cargo handling techniques are but a few of the
most recent developments to which ports must respond. Another,
spawned by necessity and massive social pressure, is the need
for preserving environmental balance. Clearly, ports and harbors
of the future must be planned and designed to accommodate change.
The purpose of this report is to aid those who are involved in
and responsible for port and harbor planning and design. It is
hoped that through the use of the guidelines presented herein,
marine facilities may be developed which are more rational, flexible
and thus more functional.
The Economic Impact of Deepwater Terminal in Texas. Daniel M. Bragg and James R. Bradley. November 1982. 55 pages. $3. TAMU-SG-72-213. NTIS-COM-73-10514.
This report is the first known effort to
assess the economic multiplier effect of an offshore, bulk-unloading
ship terminal in the United States. The primary impact of a Texas
deep-water liquid-bulk terminal will be reflected in growth of
the oil refining and related industries in the state. Discussion
considers not only what effects are expected to result from construction
and operation of the facility, but also what may happen to the
state's economy if the terminal is not built. A study area is
defined, a methodology for economic impact determination is established,
and the nature of the inputs into the Texas Input-Output Model
Economic Analysis of the Petrochemical Industry in Texas. Norman C. Whitehorn. May 1973. 78 pages. $3. TAMU-SG-73-203. NTIS-COM-73-11409.
Based on data collected from 74 Texas petrochemical
firms for the year 1971, this study attempts to determine the
petrochemical industry's total economic impact upon the economy
of Texas by analyzing employment and payrolls, sales, value added
to manufacture, capital expenditures and investments according
to the multiplier concept. Major factors concerning raw materials,
markets, transportation and the economic outlook for the petrochemical
industry in the future are discussed.

Indirect Economic Effect From Intracoastal Waterway Commerce in Texas. Christian Phillips. July 1974. 115 pages. $3. TAMU-SG-74-218. NTIS-COM-75-10065/AS.
This report evaluates effects of marine-related
activities on non-basic sectors of the economy. Emphasis was placed
on industrial development relating to numerous, inexpensive services
provided by water transportation. Determination of indirect economic
effects was based on an initial calculation of the Gulf Intracoastal
Waterway's contribution to the five coastal standard metropolitan
statistical areas. Included are discussions of historical trends,
population, employment, income, industrial growth, effects of
World War II, indirect economic stimuli and transportation.
Impact of Commercial Shrimp Landings on the Economy of Texas and Coastal Regions. Lonnie L. Jones, John W. Adams, Wade L. Griffin and Jeffrey Allen. December 1974. 18 pages. TAMU-SG-75-204.
Amount of economic activity generated by
the shrimp industry for the state of Texas and for three coastal
regions in Texas is estimated in this report. In 1971, the value
of commercial shrimp landings in the state of Texas was $63.9
million. In the coastal regions of Brownsville-Aransas Pass, Port
Lavaca-Galveston and Beaumont-Port Arthur, this value was $37.6,
$23.6 and $2.7 million, respectively. Direct, indirect and induced
impacts of commercial shrimp landings are estimated.
Cost-Efficient Cargo Distribution Among Transportation Modes. Christian Phillips. March 1976. 78 pages. $3. TAMU-SG-76-206. NTIS-PB-253-969/AS.
Operational efficiency of transportation
network connecting five selected locations that are accessible
by rail, truck and barge modes is evaluated. Costs of moving the
existing and anticipated flow of commodities on the Texas Intracoastal
Waterway are determined. It is hypothesized that the present method
of distributing chemicals, fuel, primary iron and steel products
among specified locations is inefficient. A linear programming
model is formulated to minimize total cost of distributing a given
volume of commodities among specified locations.
Economic and Production Aspects of the Gulf of Mexico Shrimp Fishery. John P. Nichols, Wade L. Griffin and Vito Blomo. June 1978. pp. 301-315. TAMU-SG-78-801. NTIS-PB-286-071/AS.

Economic Impacts of Recreational Boat Fishing in the Houston-Galveston Area of the Texas Coast. R.B. Ditton, A.R. Graefe and G. Lapotka. September 1980. 46 pages,16 tables. $2. TAMU-SG-80-206. NTIS-PB-81-140-980.
The saltwater fishing patterns and economic
impacts generated by recreational boat fisherman in the Houston-Galveston
area of the Texas coast were investigated. Data were obtained
through a mail survey of registered boat owners residing in an
8-county area surrounding Galveston Bay. Saltwater boat fishermen
spent more than $31 million for their fishing trips in 1978, with
bay fishermen spending $26,460,000 and offshore fishermen spending
$5,046,000. Non-local bay fishermen spent $7,439,000 in bayshore
communities and non-local offshore fisherman spent $1,970,000
in coastal communities. The economic impact of saltwater boat
fishing trips in the region was $79,751,000. Also discussed are
other factors to be considered when assessing the values and benefits
of saltwater boat fishing.
Costs and Returns Trends in the Gulf of Mexico Shrimp Industry, 1971-78. John P. Warren and Wade L. Griffin. In Marine Fisheries Review, February 1980. pp. 1-7. 4 figures, 5 tables. TAMU-SG-80-817.
The profitability for Gulf shrimp vessels
in recent years has been highly variable, due largely to changes
in input costs, shrimp prices, landings, and the cost, financing
terms, and configuration of vessels. It has also been shown that
based both on the results of very good years and on the results
of a number of highly varied years, ownership of a Gulf shrimp
vessel can be a satisfactory investment over an extended ownership
A Generalized Budget Simulation - Installation Manual for Budget Simulation System. Wade L. Griffin, Charles M. Adams, Linda A. Jensen. October 1983. 92 pages. $3. TAMU-SG-83-201
This manual describes the installation
and testing of either the Aquaculture Budget Simulation System
or the Vessel Budget Simulation System. The basic designs of each
system is similar enough that installation procedures are the
same except for reference-to-file names specific to one system
or the other. This manual is written in general terms; specific
references to the individual systems are in the tables. It is
designed to be used in conjunction with the specific operating
manuals for aquaculture (TAMU-SG-83-202) or vessels (TAMU-SG-83-203).
A Generalized Budget Simulation Model for Aquaculture. Wade L. Griffin, Charles M. Adams, Linda A. Jensen. October 1983. 113 pages. $5. TAMU-SG-83-202. NTIS-PB-83-144-626.
The Aquaculture Budget Simulator System
enables a user to build and operate a model of an aquaculture
or mariculture facility. The primary use of this system will be
to create budgetary information to aid potential investors in
decision making and to provide a tool for economic research efforts
concerning aquaculture. This system consists of two programs,
a data management program in COBOL and a budget simulation program
in FORTRAN. This manual describes the use of each. It is intended
to be used in conjunction with the separate installation manual
A Generalized Budget Simulation Model for Fishing Vessels. Wade L. Griffin, Linda A. Jensen, Charles M. Adams. January 1983. 120 pages. $5. TAMU-SG-83-203. NTIS-PB-83-171-771.
The Vessel Budget Simulator System enables
a user to select and equip a vessel to be operated in any fishing
ground normally frequented by U.S. owned vessels. The physical
flow of inputs into the production process aboard a vessel is
simulated to produce the information required for financial reports.
The system consists of two programs, a data management program
in COBOL and a budget simulation system in FORTRAN. This manual
describes the use of each. It is intended to be used in conjunction
with the separate installation manual (TAMU-SG-83-201).
User Guide for General Bioeconomic Fishery Simulation Model (GBFSM). Wade Griffin and William E. Grant. April 1983. 117 pages, 14 figures. $5. TAMU-SG-83-204. NTIS-PB-83-205-088.
This manual describes a General Bioeconomic
Fisheries Simulation Model (GBFSM) designed for use in management
programs of marine fish species that do not exhibit a significant
relationship between the size of the parental population and the
number of young recruited into the fishery. The purpose of GBFSM
is to predict how alternate management policies will affect a
fishery. GBFSM's design is versatile enough to be applicable to
a wide range of fisheries.
Implications of Investing Under Different Economic Conditions on the Profitability of Gulf of Mexico Shrimp Vessels Operating Out of Texas. Ernest Tettey, Christopher Pardy, Wade Griffin and A. Nelson Swartz. In Fishery Bulletin 82(2): 365-373 (1984). TAMU-SG-86-809.
Due to the inflationary trend in recent
years coupled with fluctuating shrimp prices, the shrimp business
has become a highly uncertain undertaking. The financial performance
of a sample of the Gulf of Mexico shrimping fleet, operating out
of the Texas coast, was examined over a 10-year period (1971-80).
The results indicate that investments made in the early part of
the 1970s performed better than those made in the latter part.
Periods of low inflationary levels appeared to be more favorable
to investments in the shrimp fishery than periods of high inflationary
levels. In terms of economic profits, steel vessels generally
did better than wooden ones. Medium-sized vessels were the most
efficient vessels to operate in the Gulf of Mexico.
Implications of Tax Policy on Investment in a Common-Property Resource. Tettey, Griffin, Penson, Stoll. North American Journal of Fisheries Management 6:100-104, 1986. TAMU-SG-86-834.
This study employs a financial model to
examine the aggregate investment expenditures for Gulf of Mexico
shrimp vessels. Specifically, the impacts of tax policies-investment
tax credits and income taxes-on investment decisions in the Gulf
shrimp fishery are evaluated. Contractionary tax policy is an
effective tool in limiting entry to the shrimp fishery and, thereby,
controlling the problem of overcapitalization. Decreases in the
investment tax credit rate, increases in the income tax rate,
or a combination of both policies will curtail investment activities
in the fishing industry. Implementation of such tax schemes should
raise total revenues of vessel owners, in the long run, from what
they otherwise would have been.

Investment and production costs are examined
for a semi-intensive farm that purchases postlarvae and operates
in the southern United States. Total investment decreases as pond
size increases for a given size facility. Investment per kilogram
of annual average production ranges from just under US $20.00
for a 20-surface ha farm using 2-ha ponds to $80.00 for a 400-ha
system using 20-ha ponds. Operation costs per kilogram decline
as the size of the system and the size of the ponds increase.
It costs $10.10 to produce one kilogram of shrimp on a 20-surface
ha farm using 2-ha ponds compared to $5.50 on a 400-surface ha
farm using 20-ha ponds. In comparing the operation of a semi-intensive
200-ha farm in Ecuador with a similar farm in the United States,
costs of production were $3.12 and $5.83 per kilogram, respectively.
The after-tax internal rate of return (IRR) was 59 percent in
Ecuador and 21 percent in the United States. These IRRs were calculated
under the assumption that production, costs and prices received
are constant over the investment period (10 years) considered.
When risk and timing of investment are considered, these IRRs
The Gulf Coast Intracoastal Waterway. W. Younger. 1989. 7 pages. Single copies free. TAMU-SG-89-103.
The GIWW is an integral part of the total
inland transportation system of the United States. Stretching
for more than 1,300 coastal miles of the Gulf of Mexico, this
manmade, shallow-draft canal moves a large variety and great number
of vessels and cargos, supplying both domestic and foreign markets
with essential goods. The canal provides access to sport and commercial
fishing by physically connecting the bay systems of the coast.
It also has been used as a recreational outlet for boating, birding,
water skiing and other leisure pursuits. Although direct users
are well acquainted with the GIWW, many others are unaware of
the impact it has on their lives. This brochure describes the
The Importance of Seafood-linked Employment and Payroll in Texas. Michael G. Haby, Richard A. Edwards, E. Anthony Reisinger, Richard E. Tillman and William R. Younger. June 1993. 10 pp. TAMU-SG-93-503.
The economic importance of the Texas seafood
industry cannot be measured solely by statistics from the commercial
fishing industry. The seafood industry harvests a renewable resource,
processes the catch into a wide mix of food products, and distributes
them nationwide. Obviously, the scope of such business activity
extends far beyond the harvest sector. This report quantifies
the employment and payroll created by the seafood industry, beginning
with those firms supplying commercial fishing enterprises and
ending with retail interests. For every 1,000 Texas jobs, five
are seafood-linked, and for each $1,000 paid to working Texans,
$3 are seafood-linked. Among coastal counties, the seafood industry
is often the largest taxpayer as well as the largest employer.
