What do creek fish eat

Life History: Creek chubs spawn in the spring as water temperatures approach C. Male creek chubs excavate small nests in the sand or gravel above or below riffles. After spawning, pebbles are piled onto the nest to make a small mound. Creek chubs consume a varied diet of terrestrial and aquatic invertebrates and small fish. Like brook trout, they take advantage of shelter provided by deeper pools, undercut banks, and fallen trees in small streams. However, they are more tolerant of high water temperatures than brook trout and are therefore found in a wider variety of stream types across their range in New Hampshire.

Things You'll Need. The Types of Arowana. Little creek chubs even have to watch out for bigger creek chubs. Not too many humans eat creek chubs, although they reportedly are tasty. Some anglers and bait dealers harvest them for bait. How Do They Reproduce? In streams, creek chubs excavate dig out a pit in gravel beds where there is a moderate current. Using his mouth, the male piles the pebbles upstream of the pit, which forms a ridge as he works downstream.

The final product is a ridge up to 30 cm 12 in long with a shallow pit at its downstream end. Once the "ridge-pit" is built, the male defends it from other male creek chubs and sometimes other species. When a female enters the nest, the male encircles her front with his body and they spawn. The female leaves immediately. She may return or swim to another nest. Feeding minnows in captivity is quite different. Some minnow breeders and people who keep minnows in ponds allow their fish to feast on the algae and phytoplankton that grow in the tanks or ponds.

Adding a small amount of high-phosphorous plant fertilizer 1 to 2 tablespoons per gallons of water stimulates algal growth and phytoplankton blooms. Captive minnows also eat commercial food, preferably high-protein 36 percent or more minnow food or catfish food. It is important to select food that comes in grains or flakes small enough for the minnows to eat. In a pinch, you can crush pellets so minnows can consume them more easily.

The most readily available fish food is tropical fish food or goldfish food from the pet store, which is a good substitute when supplemented with freeze-dried bloodworms or crushed brine shrimp. The most important consideration when it comes to feeding minnows is quantity because overfeeding is one of the most common causes of death in captive minnows.
