Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …

Fisheries Report No I (1) - The Shark Bay Fishery On Snapper Chrysophrys Unicolor (Quoy And Gaimard), B. K. Bowen

Fisheries Research Reports

As regards both catch and value, the Shark Bay snapper fishery is the second most important scale fishery in Western Australia. Until 195%, the fishing was done solely by means of hard-lines operated from beats drifting over the snapper patches. In 1959 traps were first used with great success and in 196) this method of fishing was again the principal technique.

Prior to the 1960 season there were several suggestions that the use of traps would have a deleterious effect on the fishery. On October 19, 1959, the Western Australian League of the Professional Fishermen's Association wrote to the Fisheries …
