New study reinforces link between gill size and oxygen uptake in fish
Data from 33 fish species further supports the argument that small differences between fish’s oxygen consumption increase and gill surface area growth do not invalidate the principles of the Gill Oxygen Limitation Theory (GOLT).
Taking seriously the explanations on shrinking fish in a warming world
Given that the temperature increase and fish shrinking trends are not slowing down, the debate around the mechanistic models that explain their causes has become nothing but heated.

Want to read Dr. Daniel Pauly’s PhD thesis? This FCRR contains the 1979 dissertation, but with minor typographical errors corrected and tables and figures reorganized for clarity.
Keep growing – Fish’s growth is not reduced by spawning
Contrary to what is stated in biology textbooks, the growth of fish doesn’t slow down when and because they start spawning. In fact, their growth accelerates after they reproduce, according to a new article published in Science.
Unrelated theories coincide on link between respiratory stress and fish reproduction
A physiological explanation and an evolutionary explanation related to the moment fish become sexually active – and spawn for the first time – have turned out to be two sides of the same coin
Sea sponges need oxygen, as fish and people do
New research indicates that sea sponges’ growth depends on their oxygen supply, in a manner similar to more complex animals such as fishes.
