The movements of adult Atlantic salmon Salmo salar were determined as they migrated to spawning habitats in a large lacustrine catchment, Lough Neagh, in Northern Ireland. The minimum average ground speed of S. salar through the lake was 2·1 km day(

The upstream migratory behaviour of wild and ranched Atlantic salmon Salmo salar in a small Irish coastal spate river was investigated using acoustic telemetry. Prespawning migratory behaviour was investigated including movement patterns at a large n

An enhancement programme based on stocking 0+ year age-class Atlantic salmon Salmo salar, conducted in the River Bush, Northern Ireland, U.K. over the period 1996-2005, was reviewed with reference to the performance and biological characteristics of

The effect of ration size on the growth of the carcase, liver and ovary in female three-spined sticklebacks, Gasterosteus aculeatus L., was studied experimentally at monthly intervals throughout the annual reproductive cycle. Temperature and photoper

The relationships between the maximum, daily food consumption, body weight and water temperature for the stickleback, Gasterosteus aculeatus L., and the minnow, Phoxinus phoxinus (L.), were studied. The two species occupy the same lakes in mid-Wales,

The effect of ration on the growth of the three-spined stickleback, Gasterosteus aculeatus, was studied over the temperature range 3·19°C, which corresponded to the range in their natural habitat. With an ad lib ration, the specific growth rate inc

In a population of Gasterosteus aculeatus living in an infertile, upland lake, the fish bred at the age of one year and few survived to breed again. The highest growth rates were achieved in the first month of life, but in comparison with other popul

Laboratory studies on the thrce-spined stickleback provided predictive equations for the relationships between food consumption, faecal production and growth, and between respiration rate and body weight. These equations were used to estimate the ene
