White Bass

Other Species

Characteristics - slab-sided, blue gray to silvery spiny-rayed fish; dorsal, caudal and anal fins slate
gray, pectoral fins and belly white; dorsal fin separated into two lobes; few attain weights greater
than 2-3 pounds. 
Distribution - Red & Winnipeg Rivers, Lake Winnipeg (and rivers flowing into it on the eastern side of the lake)
Foods - fish, insects and crustaceans. 
Expert's Tip - try fishing white and/or yellow jigs (1/8 ounce) in tandem where you see the
schools of white bass chasing minnows to the surface. 

Other names -- white bass, striped bass, silver bass. 

The white bass is common to abundant throughout the Red and Winnipeg rivers. Sizable populations presently inhabit these rivers and are generally under-utilized as a sport fish in the province.  Some fishing T.V. programs have come up to Manitoba in the spring to demonstrate how healthy the populations are..... 200 fish days are not out of the question

Typical white bass habitat is the deep, quiet pools of medium to large rivers and the mid-water
environment of lakes and reservoirs. They are most frequently found utilizing locations with sand
and gravel bottoms in clear to slightly turbid water. 

The white bass is a slab-sided, blue-gray to silvery, spiny-rayed fish with slate gray dorsal, caudal
and anal fins, white belly and pectoral fins. It has 5 to 7 longitudinal dark colored body stripes.
Stripes on the body are usually interrupted but not as sharply broken or offset above the anal fin as
other fishes in this family. The dorsal fin is separated into two complete lobes; the first contains 9
spines and the second has a single spine with 13 to 15 soft rays. The anal fin is comprised of 3
spines graduating in length followed by 11 to 13 soft rays. The mouth is slightly oblique with the
lower jaw projecting slightly beyond the upper jaw. 

Spawning is a spring ritual that occurs in Manitoba from mid may through late-June at water temperatures
ranging from 58 to 70 degrees F. Sexually mature fish form schools, often unisexual groups, that
move onto shoals or estuaries prior to spawning. Actual spawning commences when several males
surround a female and the group swims about scattering eggs and milt near the surface. The eggs
are small, averaging about .031 inch in diameter. Fecundity varies from about 241,000 to 933,00 per
mature adult female, with the number of eggs produced proportional to body size. Once released,
the eggs are fertilized and gradually sink to the bottom where they adhere to rocks and bottom
debris and hatch in several days. No parental care is given eggs or newly hatched fry. 

Growth of white bass is rapid, averaging 4 to 6 inches in the first year, 9 to 10 inches in the second
year, and 12 to 14 inches by the end of the third year. Most males mature at age II, while females
mature at age III. White bass seldom live beyond 4 years and few attain a size larger than 2 or 3
pounds. 

White bass habitually forage in early morning and late afternoon, while adults are sometimes
observed feeding during darkness. Their food consists of insects, crustaceans and fish, with the
latter making up the bulk of the adults diet. This species is highly mobile, moving about in large
schools, voraciously feeding on other schooling fish, such as Lake Winnipeg shiners, goldeye and mooneye, and small whitefish and tulibee.
