In the endemic area, with movement restriction, the PD-affected sites have been allowed to keep their fish until slaughtering time.
Up in the Lofoten Islands, he went line fishing and slaughtering Arctic Cod.
The mortality rate between 52 dpf and 7 months of age was < 0.2% throughout, and we found no differences (F = 0.65, p > 0.63, n = 12) in fish weight between treatments for either sex at the end of the experiment when fish were slaughtered (9 months; mean = 232 349 mg).
They were grown to an objective of 200 g mean weight, where 737 to 775 fish were slaughtered in each site, and their parentage was recovered using 6 to 7 microsatellite loci, resulting in 98.9% unique assignments.
The fish were slaughtered at 2 years of age, with an average weight of 1.1 kg.
The surviving fish were slaughtered or selected as breeders during three different periods between March 21 and August 24 , 2005
In that case, it is still unknown whether genetic variation in uniformity of BW changes since fish are slaughtered at a younger age.
All pens (n = 33) except one at site D (where fish were slaughtered) were sampled before and between 3 and 16 days after treatment; only two sites and around half of the pens were sampled after day 23.
For BE, sex and sexual maturity status were recorded based on external sex characters, whereas for PE, since fish were slaughtered, sex and maturity were identified based on the morphology of the gonads.> In total, 22 175 and 20 865 individual records were available for BWBE and BWPE, respectively (Table 1).
There's also the bigger picture to get anxious about: the head-spinning equations explaining how much energy is expended on the recycling process itself, and the articles claiming that our carefully separated plastics are all shipped off to China in fish-slaughtering supertankers, where they're picked over by small children wearing rags.
Many present commercial methods of slaughtering fish for food cause stress and aversive behaviour, which could be considered inhumane.
