Application of lipidomics in bivalve aquaculture, a review

Bivalve production is a relevant aquaculture activity in Europe; however, it is not
developing with same extents of other aquaculture sectors due to causes connected
with regulation stringency, labour cost, space availability, habitat loss as
well as variability in recruitment events, climate change and diseases. Understanding
the physiology and nutritional requirements of bivalves during aquaculture
activities might result beneficial to fuel up the development of the sector. Lipids
are important molecules as they are relevant components of cellular membranes
acting in several physiological processes like reproduction, growth, immunological
responses and energy reserve. Nevertheless, lipid diversity is still poorly understood
despite the research efforts of the last decades. Technological advancements
provide tools to unveil such diversity. Lipidomics, a branch of metabolomics, is
the science targeting the lipidome (e.g. the totality of biological lipids in an organism).
In this review, lipidomics, and its related concepts, are discussed providing
an overview of recent lipidomics studies on bivalves. Lipidomics could result in
several advantages if compared with traditional lipid profiling techniques; however,
aims and scopes of future lipidomics studies should be expanded. Here, possible
future applications of lipidomics in the context of bivalve production are
presented and discussed. Unveiling the lipidome of marine bivalves could aid disclosing
important information regarding nutrition, biology, physiology and epidemiology
on bivalves. This knowledge, once applied, has the potential to
improve bivalve production and the resilience of the sector to environmental
changes.
