Effect of line sink rate on albatross mortality in the Patagonian toothfish longline fishery
, weight spacings of 40 m, or thereabouts, would seem appropriate. This would result in 28 weights ... 1.2 m intervals along the mother line. Snood lines were 3 mm in diameter and 50 cm in length. Line ... hook line running parallel to the mother line. Hook lines bore 3 mm diameter, 0.7 m long snood lines ... presented as a family of polynomial and logarithmic regressions expressing line sink rate (Figure 3), sink ...
