Blue Pike Recovery Plan (5425 words) |
 | Scott and Crossman (1973) described the blue pike from the Niagara River as slate-blue or steel-blue on the dorsal surface, ice-blue to silvery on the sides, and silvery to white on the ventral surface. |
| Blue pike inhabited primarily the eastern and central basins, whereas walleyes were concentrated in the western basin; they spawned in deeper and cooler water than the walleye; they, like walleyes, spawned almost entirely in open lake areas where they were most abundant; and they usually spawned in May, whereas walleyes usually spawned in April. |
| Blue pike were reported to be vulnerable to introgressive hybridization at that time because their stocks were severely depleted by exploitation and were subjected to stumper oxygen depletion and competition with rainbow smelt, Osmerus mordax, for food and space. |
