| The effects of water temperature on pollack (Pollachius pollachius) spawning features were individually assessed. During the spawning period, nine fish sets, each composed of one female and two males (mean body weight: 2.5+/-1.0 kg), were placed in small-volume tanks (2 m(3)). Fish sets were held at 8, 10, or 12 degreesC (n=3 for each temperature). Three females released eggs at 8 and 10 degreesC, while only two spawned at 12 degreesC. One hundred thirty-one individual spawns were collected from the eight spawning fish sets. The number of spawns collected per female was significantly lower at 12 degreesC (3.0+/-3.6), compared to 10 degreesC (17.3+/-10.1) and 8 degreesC (23.3+/-2.5). Egg number (eggs kg(-1) BW) was significantly lowered at 12 degreesC... |
