Essays on the management of fisheries in the presence of strategic interactionsRuseski, Gorazd 05 1900 (has links)
The following three essays present an analysis that combines well-known models of fisheries
management with contemporary theories of international trade and industrial organization.
The general theme of the thesis is that countries' fisheries management policies
can affect the strategic interaction between their fishing industries. The first essay examines
the problem of noncooperative management of international fisheries by analyzing
the strategic rent-shifting roles for such well-known national management policies as fleet
licensing and effort subsidies. It is shown that the noncooperative equilibrium in each
policy takes the form of a prisoner's dilemma with dissipated rents in the fishery. It is
also shown that strategic effort subsidies can only lead to incomplete rent dissipation but
strategic fleet licensing can lead to complete rent dissipation.
The second essay develops a theory of cooperative management of international fisheries
by considering negotiation between countries over the same fleet licensing and effort
subsidy policies considered in the first essay. The outcomes of negotiation over these policies
are compared to the corresponding noncooperative outcomes, on the one hand, and
to the efficient outcome on the other. It is shown that negotiation over effort subsidies in
the absence of side payments is efficient, but negotiation over fleet sizes in the absence of
side payments is inefficient.
The third essay develops a two-stage two-period model of a 'domestic' country and
a 'foreign' country whose respective fishing industries harvest from separate fisheries for
the same international market. The domestic country uses a harvest policy to regulate
the harvest by its fishing industry, but the harvest by the foreign fishing industry is
unregulated. Two types of fisheries are considered. In the case of schooling fisheries,
the domestic country may choose a conservative harvest policy in the first period if it
can induce the biological collapse of the foreign fishery in the second period. In the case
of search fisheries, the domestic country always chooses a conservative harvest policy in
the first period in order to induce the economic degradation of the foreign fishery in the
second period. The results suggest that international fisheries trade in the presence of
divergent national fisheries management regimes could have unexpected consequences for
world fisheries. / Arts, Faculty of / Vancouver School of Economics / Graduate

The impacts of extended fisheries jurisdiction on seafood trade among selected countries : market share and product substitutionSiaway, Arthur 25 August 1986 (has links)
By 1976 extended fisheries jurisdiction had been
declared by most coastal states and territories of the
world. The new regime of property rights was expected to
affect seafood production costs which, in turn, could impact
on seafood trade and the competitive positions of
producing countries. In theory this policy should bestow
upon coastal nations and territories a comparative advantage
in seafoods. Thus, in studying price and nonprice
competition as factors that influence seafood trade, a
third factor (the effects of extended fisheries jurisdiction
EFJ) is added.
The best available data are aggregative. These data
are used to analyze the influences of the three factors
listed above on seafood trade.
In the first part of the investigation, Canada and
the U.S. are considered. The annual growth of each
country's exports of fresh, frozen, and chilled fish to
selected countries is computed using the constant market
share approach. The calculated annual growth is partitioned
into three effects (or components); namely; (1)
competitiveness effect, which measures the portion of
growth due to (price) competitiveness; (2) market distribution
effect, which measures growth due to the
(re)direction of exports to more rapidly growing markets;
and (3) market size effect, which accounts for growth
caused by overall growth in world demand.
Both countries have gained substantial shares of the
Japanese and European markets, but Canada's share of the
U.S. market has declined due to increased competition from
U.S. domestic producers. The U.S. share of every considered
market has increased, in most cases, substantially.
The second part of the study considers eight exporters
of fish to the U.S. Various econometric models
are used to analyze cause and effect relationships between
changes in relative prices and changes in the market
shares of pairs of countries/regions. Results indicate
significant nonprice influence and symmetrical EFJ effects
on product substitution. / Graduation date: 1987

Post-mortem quality changes in iced Pacific shrimp (Pandalus jordani)Cavazos, Sergio Flores 25 October 1972 (has links)
The biochemical and organoleptic changes that took place in
raw whole Pacific shrimp and in the cooked meat during eight days
of iced storage were investigated.
A steady increase of both microbial numbers on the raw shrimp
and pH in the raw shrimp and cooked meat was observed.
The levels of total and non-protein nitrogen and total carotenoid
pigment decreased during the storage period. Tyrosine levels showed
a. decrease in the raw shrimp, but a progressive increase in the
cooked meat was observed. Although proteolytic and polyphenolase
activity in the raw shrimp decreased during storage, the losses in
nitrogenous components was probably related to a combination of
the autolytic degradation of the shrimp coupled with the washing action
of melting ice.
Trimethylamine oxide levels were shown to decrease in raw
shrimp daring storage due to the washing action of melting ice and
its reduction to dimethylamine and formaldehyde and in lower
amounts, to trimethylamine. The latter, probably is the result of
bacterial activity, while the former is due to the action of enzyme
systems in the shrimp. Levels of dimethylamine and formaldehyde
increased in a parallel manner during the storage period. Trimethylamine
levels also increased, but at a much slower rate.
Organoleptic quality as shown by taste panel evaluations progressively
declined during the storage period. Dimethylamine and
formaldehyde levels appeared to be more sensitive indices of cooked
shrimp quality than microbial numbers, pH and trimethylamine
levels. / Graduation date: 1973

Development of a product which simulates abalone texture from Alaska Pollock (Theragra chalcogramma) SurimiChang, Seong Ook 26 August 1988 (has links)
The objective of these studies was to develop an
analog from surimi that would resemble abalone.
Preliminary studies involved the standardization of batter
preparation conditions, such as pH adjustment, optimum
moisture content and batter mixing time. The texture of a
gelled analog prepared with different protein adjuncts
egg white, gluten and bovine serum albumin) was compared
with cooked abalone for hardness, elasticity, and
cohesiveness by a trained sensory evaluation panel and by
instrumental methods.
Serial levels of sodium carbonate were used to adjust
the pH of the sol from pH 6.75 to 7.73. As the pH value
rose, the textural strength of kamaboko correspondingly
increased. The 0.1% level of sodium carbonate was
determined suitable for further use.
The moisture level in kamaboko caused significant
variations in hardness (P<0.001) and cohesiveness (P<0.001). At the lowest level of moisture tested,
73.24%, gel hardness was greatest (l27N/g); with a 5%
increase in moisture, the gel hardness was lower (52N/g).
Sol mixing time (solubilization of myofibrillar
proteins) was a very important factor to significantly
affect gel texture for properties of hardness (P<0.00l),
elasticity (P=0.002) and cohesiveness (P<0.001). To
produce a strong, elastic and cohesive gel, 30 minutes
mixing was required.
In serial concentrations (O to 4%), egg white,
gluten, and bovine serum albumin, were evaluated for
enhancement of textural parameters in order to produce an
imitation abalone product. The addition of either egg
white or gluten at the two percent level resulted in the
greatest hardness and most cohesive gels (P<0.001). Two
percent added bovine serum albumin significantly improved
gel hardness and elasticity (P=0.003 and P=0.0149,
respectively).
A shredded gel containing one of three protein
adjuncts was effective in varying the final gel texture
when incorporated with a surimi-based carrier. In overall
parameters, the trained sensory evaluation panel judged
the analog gel containing bovine serum albumin texturized
chunks (at a 70:30 ratio to carrier) closest to cooked
abalone. The instrumental measurements of textural
parameters were slightly less discriminating than the
trained sensory panel. / Graduation date: 1989
