Here you can find some of the activities we did during the Swansea Science Festival. You can use them to make your own activities. The cards on pages 16 to 23 can be used to play the game on page 15 - who is who? These activities were created and delivered by Sara Barrento (lecturer at Swansea University); the Swansea University PhD candidates: Jessica Knoop, Ben Whittaker, Suzana Leles and master student Katie Weston. Pietro Francinetti kindly helped out packing up. A great team work and some lessons learnt – we need more volunteers for the weekend days!

Microalgae
Chlorella vulgaris is a eukaryotic, unicellular green algae.
C. vulgaris is a freshwater microalgae estimated to have
been on Earth for more than 2.5 billion years.
Chlorella is a potential
food source because it is
high in protein and other
essential nutrients; when
dried, it is about
45% protein, 20% fat,
20% carbohydrate, 5%
fiber, and 10% minerals
and vitamins.
Chlorella contains the
green photosynthetic
pigments chlorophyll-
a and -b in
its chloroplast.
The name Chlorella. is taken from
the Greek χλώρος, chloros, meaning
green, and the Latin diminutive
suffix ella, meaning small.
Through photosynthesis,
it multiplies rapidly,
requiring only carbon
dioxide, water, sunlight,
and a small amount
of minerals to reproduce.
Mass-production
methods are now
being used to cultivate
it in large artificial
circular ponds.

Lumpfish
Cyclopeterus lumpus, belong to a large group of fish that scientists call the teleosts, which
includes many familiar species such as salmon, tuna, goldfish and clownfish. However, lumpfish
differ from most teleost in some interesting ways:
No scales, instead the
body is covered in tough
skin, spikes and a lot of
mucus.
The pelvic fins form a
specialised suction cup,
allowing the lumpfish to
sit or cling to surfaces.
Eyes move
independently,
allowing the fish to see
in different directions
at the once - similar to
a chameleon.
Female lumpfish are prized for
their roe (fish eggs), which are
often used as a caviar substitute
in supermarkets.
Lumpfish have no swim bladder, a
special organ that helps with
buoyancy in the water. They are
also very fat, so are not good at
swimming.
Chromophores in the skin
and fin tissue allow lumpfish
to change colour. They use
this to camouflage and hide
against different
backgrounds. Males will turn
a bright scarlet red when
breeding.

Mussels
Mussels, like the Mytilus edulis are invertebrate
molluscs including familiar forms such as clams,
oysters and squids. Mussels dominate the intertidal
region the area that is above water at low tide and
under water at high tide, in other words, the area
between tide marks.
Mussels are filter feeders, they
feed by straining suspended matter
and food particles from water,
typically by passing the water over
a specialized filtering structure.

Rotifer
A characteristic organ for
the rotifers is the mastax
(i.e. a calcified apparatus
in the mouth region), that
is very effective in
grinding ingested
particles.
Brachionus plicatilis,
rotatoria (=rotifera)
belong to the smallest
multicellular animas
90% of the species
inhabit freshwater
habitats.
They seldom reach 2 mm in body
length. Males have reduced sizes
and are less developed than females;
some measuring only 60 mm.
The head carries the
rotatory organ or
corona which is at the
origin of the name of
the Rotatoria
(bearing wheels).
The retractable corona
assures locomotion and
a whirling water
movement which
facilitates the uptake of
small food particles
(mainly algae and
detritus).

Artemia or brine shrimp
The ability of the
Artemia to produce
dormant eggs, known
as cysts, has led to
extensive use of
Artemia in
aquaculture.
The cysts may be
stored for long
periods and hatched
on demand to provide
a convenient form of
live feed for larval fish
and crustaceans.
Artemia salina, are small crustaceans found worldwide in inland saltwater lakes,
but not in oceans. Artemia are able to avoid cohabiting with most types of predators,
such as fish, by their ability to live in waters of very high salinity (up to 240 g/L).
Artemia is a filter feeder of organic detritus, microscopic algae as well as bacteria.

Lumpfish
Lumpfish display cleaning behaviour. This a very
difficult task, which involves lumpfish inspecting the
skin of a client fish (such as salmon) for parasites
(such as lice) to eat. As a result, the salmon is healthy
and the lumpfish eats a nutritious meal. This
partnership is an example of mutualism, and is very
useful to keep salmon healthy on farms.
Not all lumpfish are good at cleaning. Scientists at
Swansea University, in collaboration with Marine
Harvest Scotland, are trying to discover what
makes certain lumpfish so successful at cleaning.
Would you be a good cleaner-fish?
Can you find the lice hiding on this salmon?

Who is who?
Primary Producers Filter feeders Predators
feed by straining suspended
matter and food particles from
water, typically by passing the
water over a specialized
filtering structure. Can you see
any filter feeders in the
aquarium?
organisms take energy from
abiotic, or non-living, sources
and turn it into usable energy,
examples include plants,
algae, cyanobacteria,…
any organism that exists by
preying upon other
organisms. Can you see any
predators in the aquarium?
