Fishing story and rivers

fish propagation and rescue paintings

the 1870's were years of increasing alarm over the disappearance of

fishery resources in the america and the upper Mississippi river

valley. on February 9, 1871, with the aid of a joint resolution of the house and

senate, the office of the united states commissioner of fish and

fisheries became mounted ( u. s. comm. fish and fisheries, 1873, p.

xli). the location turned into with out salary and Dr. Spencer f. bared of the

Smithsonian group become appointed the first commissioner. in 1874,

Wisconsin, Missouri, Iowa, and Minnesota installation their first fish commissions and Illinois accompanied suit in 1879 (Wisc. comm. fish, 1910,

p. thirteen; Bennett and Campbell, 1950, p. 118; Iowa fish fee,

1876; Minn. nation game and fish comm., 1924, p. 7; sick.nation fish

comm., 1901, p. thirteen).

the u. s. commissioner of fish and fisheries was authorized at

first most effective to make investigations, but in 1872 his obligations had been extended

to consist of the synthetic propagation of fish, on the idea of the

american fish-culturists association, now the american fisheries

society, which met in albany, n. y., february 7, 1872 (u. s. comm.

fish and fisheries,1874, p. xvi). that yr messrs. seth green and

clift, in behalf of the u. s. government, located 30,000 american shad

(alosa sapidissima) within the allegheny river and 25,000 inside the mississippi river some miles above st. paul, minnesota. it become diagnosed

that the stocking may not be successful "however the effects to be acquired, in the occasion of its opportunity, are of such transcendent significance to the food supply of the u . s . a ., and the cost of the test

so very trifling, that it'd be inexcusable now not to try it" ( ibid. p.

xviii). "the prime item become to introduce the fish into the waters of

the mississippi valley due to the fact these waters are by means of their nature the not unusual assets of the union.. . . young fish introduced into. . . top

mississippi in minnesota . . . might of their return from the ocean,

traverse a large variety of states, and, of route, be susceptible to be captured at any factor before achieving their spawning floor." (ibid. p.

liv). dr. baird noted that china's biggest river, the yangtze, contained

abundant "shad" and that the distance the fish would have to travel

to the waters of all of the tributaries of the mississippi, besides the upper

missouri, was an awful lot less than that traversed through the "shad" of china.
