most unfortunate mix-up seems to have occurred over the name of this fish.

scientific name of

unfortunate common name of Meagre.
as the fish known as Capros aper, Boar Fish or Zulu
Fish, seems to have acquired the name of another
fish by accident. Meagre for the meagre meal it makes seems to be most
likely name for this fish. Or Maigre from the French for thin. It has shown
no signs of grunting.
to do now as all the books have inappropriate names.
Meagre, I call the Drumfish, leaving a name needed for Capros aper.
Zulu Fish is OK when they are stripy and when washed up in a net or on
the shore. Cuckoo Fish would get confused with the Cuckoo Wrasse. The first
thing Peter Weight who caught the Sussex fish said when I told him the
common names was that it was an unimpressive name.

(fatter than when caught when it looked slightly malnourished). (The fish
was transferred to another tank, which probably had insufficent oxygen
during the emergency flooding (which threatened the electrical supply).
The tank had Corkwing Wrasse, Symphodus melops,

time I had gone out of the room to set up an additional air pump it had
keeled over and could not be revived. (This is unusual.)

are common in deep water of the western English Channel but rarely strays
east up the Channel. The fish's large eye and the orange/ red colour is
well suited to deep water as the longer wave length of red light is absorbed
by water before the blue and greens (which are reflected) and therefore
red coloured marine species appear dark or black at depth. The
Boarfish, like the John
Dory, has a protrusible (telescopic) mouth,
which is used for catching small species.

caught, it is abundant in deepish water (on the edge of the continental

that normal fishing methods do not capture this small fish. All records

records are newsworthy.

the Boar Fish
commenced to feed on frozen brine shrimp after being initially encouraged
with live daphnia. It ignored other alternative foods like boiled mussel
flesh, very small live prawns (mysid-size), micro trout pellets (formed
into a ball). It seemed initially to feed better when the circulatory water
pump (powerhead) was turned off, but within an hour it recognised the food
and fed when the pump was on. Feeding was observed when the aquarium fluorescent
light was on and was continuous swallowing of very small particles of shrimp
collected in mid-water, and the water was kept in motion by the use of
an airstone attached to a powerful diaphragm air pump. If the particle
was disliked it would be examined and ignored, very occasionally it would
be swallowed and spat out again.

to Mevagissey, Cornwall, in a Pilchard net and it is one of two of these
attractive fish on display in the aquarium.
Capros aper, was brought
up in a net set for Red Mullet,
surmulatus, at 12 metres off the island of Guernsey in the Channel
Islands. The Boar Fish
is rarely caught because it is small (59 grams and a total length of 153
mm) and escapes the nets and because it usually lives at greater depths
than most nets are set.

I'm not too surprised
by the presence of the Boar
Fish (Capros aper), off
Sussex. A few years ago I was carrying out
some research work off the
Irish coast aboard a super crabber, they
loaded boxes of Boar Fish
(Capros aper) for use as bait!! which puzzled
me at the time as the size
would hardly put out a significant scent to
However, once the pots had begun to be hauled
and nearly every other pot
had a conger eel in, the reasoning became
clear. The conger eel were
cut up into steaks/chunks and used for bait
with the Boar fish (Capros
aper) merely used to bulk out the bait. I
questioned the skipper as
to the source of the Boar fish (Capros aper),
and he replied that they
bought them off local trawlers who landed
specifically for pot bait
and they were a significant component of the
bycatch in local waters.
At the end of the trip most of the bait went
over the wall as the fresh
conger eel provided the main bait source.

Boar Fish, Capros
A small family, Caproidae,
of marine fishes comprising two genera and 12 species. They were formerly
placed in the order Zeiformes with the dories, but are now placed with
the Perciformes since they have many perciform characteristics, for instance
in the caudal skeleton.
