Description The global food demand is rising, and the expanding land-based food
production is beset with environmental and health concerns. Because seafood
is nutritionally diverse and avoids or lessens many of the environmental
burdens of terrestrial food production, it is uniquely positioned to
contribute to both food provision and future global food and nutrition
security (Costello et al., 2020). Food from the sea represents only 17% of
the current production of edible meat. It is estimated that edible food from
the sea could increase by 21-44 million tonnes by 2050, a 36-74% increase
compared to current yields (Costello et al., 2020). This represents 12-25%
of the estimated increase in all meat needed to feed 9.8 billion people by
2050. Marine fisheries are very important to the economy and wellbeing of coastal communities, providing food security, job opportunities,
income and livelihoods as well as a traditional cultural identity. The
increasing exploitation of finfish resources, and the depletion of a
number of major fish stocks that formerly supported the industrial-scale fisheries, forces continued attention to the once called ‘unconventional
marine resources’, which include numerous species of cephalopods.
Cephalopod catches have increased steadily in the last 40 years, from
about 1 million metric tonnes in 1970 to more than 4 million metric tones
in 2007 (FAO, 2009), (Jereb and Roper, 2010). The number of cephalopod
species that enter commercial fisheries has continued to grow significantly
since 1984, as a result of a still-growing market demand and the expansion
of fisheries operations to new fishing areas and to deeper waters (FAO,
2010).
