Three finfish species frequently caught in the waters of the Gulf of
Manfredonia (Apulia, Italy) were studied in order to know how the flesh
composition (proximate, fatty acid, macro- and micro- element contents)
could be affected by the season effect.
The species we examined were European hake (Merluccius
merluccius), chub mackerel (Scomber japonicus) and horse mackerel
(Trachurus trachurus), which were analysed at the raw state in three catch
season and after cooking in two catch season. More precisely, European
hake and chub mackerel caught during winter, summer and fall were
analysed at the raw state. The composition of the flesh of grilled European
hake and chub mackerel was study on fish caught in winter and fall. Horse
mackerel of summer and winter catches were analysed both at the raw
and grilled state. Furthermore, an overall sensory profile was outlined for
each species in two catch season and the relevant spider web diagrams
compared.
On the whole, two hundred and eighty fish were analysed during
this research project in order to obtain a nutritional profile of the three
species. One hundred and fifty was the overall number of specimens used
to create complete sensory profiles and compare them among the
species.
The three finfish species proved to be quite interesting for their
proximate, fatty acids, macro- and micro-element contents. Nutritional and
sensory changes occurred as seasons elapsed for chub and horse
mackerel only. A high variability of flesh composition seemed to
characterise these two species. European hake confirmed its mild sensory
profile and good nutritional characteristics, which were not affected by any
season effect.
