This Study Guide has been set up for students and apprentices who want
an introduction to the knowledge and understanding needed
by the Level 3 occupational unit -
Principles of Shellfish, Non-Marine Finfish and other Marine Food
Products Product Knowledge.
is also suitable for anyone interested in shellfish, non-marine
finfish and the various other edible food products that
come from the sea, their harvesting, preparation, trading,
sales and consumption. We hope that this study guide (developed
for Lee Cooper of Seafish by Adam Whittle) will be of
interest to retailers, managers, students and others.

learner worksheets have been developed for apprenticeship
providers and assessors to use as model answers. They
can be made available upon request.

Principles unit supported by this Study Guide is a substantial
unit worth 5 credits in a vocational qualification or apprenticeship.
It is a level 3 unit and to complete it would take a minimum
of 25 hours of guided learning.

1.4 Explain the current general state of stocks for shellfish,
non-marine finfish and marine food product and species-specific
issues including quotas, sustainability and the environmental
impact of harvesting/aquaculture methods.
Describe the current state of European stocks, including
how much are harvested each year. Explain the sustainability
and the impact on the environment of different harvest methods.
Controls of wild and farmed harvest for shellfish and non-marine
finfish are typically controlled by licensed entry and a
minimum landing size allowing wild stocks to reach a breeding
age before harvest. As farmed stocks are produced in controlled
conditions and driven by market demands farm sites and sizes
are licenced and monitored rather than be controlled by
a quota system.
2.2 Describe the impact of seasonal variations and adverse
weather conditions on a specific product availability, condition,
quality and typical price
How do seasonal variations and bad weather impact availability,
condition, quality and price of shellfish, non-marine finfish
and marine food products?
Weather and holiday periods such as Christmas, Chinese New
Year and Easter cause significant variations in price and
availability. If boats can’t harvest and land products due
to bad weather, this will limit availability and lead to
high market prices. Larger companies will try and limit
these price variations by agreeing supply contracts which
is often the case for large retailers and large farming
companies supplying salmon. This is not as easy for smaller
companies or other wild harvest products available in smaller
quanities. Marine Conservation Society – buying seasonal fish
2.3 Clarify the range of shellfish, non-marine finfish
and marine food products available including different packaging
systems and processing methods such as MAP, Vac-Pack, smoking,
Describe a typical range of shellfish, non-marine finfish
and marine food products sold in UK retailers, including
different processing and packaging methods such as Modified
Atmosphere Packaging (MAP), vacuum packaging, smoked, marinated,
and dried products. Waitrose Fish Range
2.4 Describe where to find up to date information on shellfish,
non-marine finfish and marine food products for use by seafood
retailers, wholesalers and consumers.
Where would you find up to date information on marine fish
for use by wholesale, retail and consumers?
