THE CARNIVOROUS FISHES 
The Pike, Bass, Perch and other predaceous fishes are not suited to 
the household aquarium, although small ones are sometimes kept. If fed 
upon meat it is important that no uneaten particles be allowed to remain. 
COLLECTING IN STREAMS AND PONDS 
There are pleasures connected with the stocking of a wild-fish 
aquarium which are unknown to those interested only in goldfishes. The 
actual contact with Nature, the study of the fishes in their native habitat, 
the ever-present possibility of finding something new, the companionship 
and health afforded on outings are some of the more important assets of 
the collector. For this work two kinds of nets should be provided. 
These consist of a minnow seine and a large landing net of small 
mesh, fitted with a sectional rod. The seine should be operated by two 
persons. Poles are attached to the lower lines containing the sinkers, 
while the float line is pulled forward by the hand, slightly behind the 
lower line. They can be operated with great success in any shallow 
stream where the fish can be manceuvered into a corner for the final 
sweep. Care should be exercised to put back all fish not actually wanted, 
and also not to try to carry so many home that they all suffocate before 
arrival. The landing net is used mainly in streamlets. It is operated by 
a quick overhead swoop and the net pulled rapidly over the bottom 
towards the fisherman. The net should be of a depth of about 25 inches 
and had best be secured to the frame by brass rings of about 5% inch 
diameter, procurable in upholstery stores. These prevent the cutting of 
the net when dragging over stones. Very little success can be had by 
scooping upwards.
