1990s. However, it was not until the publication in 1998 of John Elkington’s book “Cannibals with forks: the triple bottom
line of 21st century business” that this concept began to gain momentum.
One of the main considerations of TBL is the possibility of quantitatively measuring the impact of certain actions of
the organization, both from an economic and social and/or environmental point of view. In addition, the TBL concept
establishes the paradigm that its main lines (economic, social and environmental) are not static or stable, but are considered
to be in constant movement due to social, political and economic pressures, changes in the economic cycle and the
inuence of certain events such as conicts of a warlike nature. Therefore, each of the lines or elements of the TBL should
be considered as a continental shelf in itself, so that it often moves independently of the others, and can be located above,
below, next to and even friction can occur between them (García López, 2015), (Shaer, 2018).
In this sense, Bertalany proposes the General Systems Theory (GST) (Bertalany, 1989), which shows a systematic and
scientic way of approaching and representing reality.
The objectives of TGS are as follows Pouvreau, (2013).
1. To promote the development of a general terminology to describe systemic characteristics, functions and behaviors.
2. To develop a set of laws applicable to all these behaviors and nally,
3. To promote a (mathematical) formalization of these laws.
It is important to highlight Aragon’s position according to his publication:
...the issue was raised by Ansah and Frimpong as follows: “If the growth of organisms under cultivation is overestimated,
it may result in unexpected losses of commercial revenue, while underestimating growth could result in poor crop planning
with respect to labor allocation, optimal feeding and harvesting time” (Aragon-Noriega, 2016).
One of the rst documented polyculture systems was developed on Negros Island in the Philippines (Puricelli et al.,
2002), the system employed 95 ha of ponds on Negros Island in 2002 and was further extended in 2003 to other nearby
islands, while by 2008 more than 60% of shrimp farms in the Philippines were using polyculture between tilapia and
shrimp (Fitzsimmons and Shahkar, 2017). Another use in the Philippines, apart from the production of two species, was to
maintain water quality and conditions by means of cages located inside the shrimp fattening ponds, with tilapia consuming
most of the waste generated by shrimp (Fitzsimmons and Shahkar, 2017).
Currently, in Ecuador there are several farms that have adopted polyculture systems, most use systems where they store
red tilapia to maintain the conditions of the pond where the shrimp are fattened, the city that has built an important
international trade with tilapia produced in polyculture ponds with giant shrimp is Guayaquil (Fitzsimmons and Shahkar,
2017).
One of the species to be cultivated in polyculture is the red tilapia (Oreochromis mossambicus), which was introduced in
Mexico in 1964 and is of great importance in the production of animal protein in tropical and subtropical waters around the
world, particularly in developing countries, where it is also known as mojarra. Tilapia farming is one of the most protable
in aquaculture, as it is highly productive due to the species’ attributes, such as rapid growth, disease resistance, high
productivity, tolerance to high density conditions, ability to survive low oxygen concentrations and dierent salinities,
as well as acceptance of a wide range of natural and articial feeds. Aquaculture accounts for 91% of tilapia production
in Mexico and is grown in 31 Mexican states, with the largest producers being Chiapas, Tabasco, Guerrero, Estado
de México, and Veracruz. In Baja California Sur, cultivation is reported for self-consumption, and Baja California’s
production in 2010 was less than one ton (Aquacultura| Tilapia | Instituto Nacional de Pesca | Gobierno | Gob.Mx, n.d.).
The other species that will produce in polyculture is the white shrimp, Litopenaeus vannamei. It began in Mexico at the
Monterrey Technological Institute, Campus Guaymas, where research was carried out by the University of Sonora in
the early 1970s until the second half of the 1980s, when commercial cultivation began. Since then, production volume
has increased signicantly, as has installed capacity, mainly in Sinaloa, Sonora, and Nayarit. However, shrimp farming
is aected by various infectious agents, which is why the industry adopts “Good Management Practices” (GMP), and
in some cases uses semi-intensive farming systems (Santos et al., 2021). These practices are carried out mainly in the
northwestern states of Mexico, where the activity has the highest production; in 2008 alone it exceeded 60% of total
national shrimp production (shery and aquaculture), white shrimp production is normally carried out in semi-intensive
ponds (Santos et al., 2021)
