Abstract

The main point of this presentation is
primarily meant to explore the issues
that GM fish have upon the
environment and society. More
specifically, the related topics seek to
explore the methods of such
processes, its potential benefits and
detriments and the reason why such
measures of having GM fish might be
needed.


Reason

The main reason as to why there is a
growing interest in the idea of
farming and harvesting GM fish, is
because of certain issues like keeping
up with the global demand for food.
As the yields for traditionally caught
fish gradually fall short in meeting
global demands that could double by
the middle of the century, it is
important that there should be an
increased focus of GM fish
aquaculture (Walsh).


Basic Process

Genetically modifying certain
organisms is a step away from the
traditional methods of breeding
certain organisms together to produce
a certain product with desirable traits.
Basically, it includes inserting desired
genes from one organism to another
and/or changing the target organism’s
gene (“What is genetic modification”).
One trick for example is to “nurture
genetically modified cells into live fry”
through the use of “primordial germ
cells”, which in turn would allow a
certain percentage to develop and
pass on that desired gene (“New
method of making GM fish”).


Benefits

There are a multitude of benefits from
the production of GM fish. One main
example is an increased growth and
maturation rate which improves
production yields (Muir). Others
includes resistance to certain diseases,
toleration of harsher environments,
better nutrition use, etc (Muir).


Graph indicates multiple scenarios in which regular fish
catch either shrinks or plateaus (Roper).

production

Summary”).

Consequences

There is also a variety of
consequences from GM fish. An
example would be an escaped GM fish
breeding in the wild, causing genetic
drift in the general population (Le
Curieux
-
Belfond

et al. 3). Other
issues includes allergies, toxicity, risks
in threatening the equilibrium of the
environment, etc (Le
Curieux
-
Belfond

et al. 6
-
8). Along with other issues
like the social and economic impact of
these GM fish (“Congress members
seek to block approval of GM
salmon”).
