To be fair, deep water specimens aren't seen near the surface for a reason. Any animal that strays that far from its range is likely to have health issues and while the death may well be due to the capture, it was likely a foregone conclusion. The asian ethic towards the see appears to be one of utilization. While I disagree with a great deal of their policy, making use of stray abyssal fish seems to be an intelligent decision from a scientific perspective. We know little about these fish and the information garnered may be of use in future conservaion efforts. If you agree with Wordsworth that we "Murder to disect" than this strategy is not a favorable one. Either way, Specimen collection has always been a staple of zoological research.
