Fig. 95.—Littoral mud-inhabiting copepods: a, Iliocryptus sordidus; b, Rhyn- chotalona jalcata, digging in the mud with its rostrum. X 25. a, after Fric and Vavra, b, after Herr. A large number of fishes find rich nourishment in the region of plant growth, and especially a favorable spawning place; for this reason young fishes are plentifully represented in this region. Thus it happens that the degree of development of littoral plant growth may have a marked effect on the fish fauna of a lake. The Konigssee (in Bavaria) without a littoral region, produces annually 1 kg. of fish per hectare; Lake Constance, the fertility of whose littoral region suffers from rather large variations in water level, produces 8 kg.; the Chiemsee (in Bavaria), whose shallow and wide littoral region is well covered with plants, produces about 20-25 kg. of fish17 per hectare. It is unsafe, however, to generalize too confidently at this point. The animal life of wave-beaten shores, where no plants are found, has a faunal composition much like that of swift water in A close observer always finds teeming life. Fresh-water sponges grow on the stones in flat, slab-like crusts, while in quiet bays they develop.
