Also, the decline due to overfishing is by far the major problem in fish stocks today.
However, as coral reefs begin to decline,
and water warms, holding less oxygen,
then the affect attributable to global warming will increase.
Climate change is likely to alter patterns of wind and water circulation in the ocean environment. Such changes may influence the vertical movement of ocean waters (i.e., upwelling and down welling), increasing or decreasing the availability of essential nutrients and oxygen to marine organisms. Changes in ocean circulation patterns can also cause substantial changes in regional ocean and land temperatures and the geographic distributions of marine species. Coastal and offshore systems are currently under heavy harvest pressure, which may threaten not only the fisheries, but also the very existence of some harvested species. Because those species are part of a larger web of feeding and other biological relationships, their depletion or loss may have important negative consequences for the ecosystems they inhabit and the reptiles, birds, and mammals that feed on them.

Not just CC but over fishing is already causing a big problem as well
Yes, some fish need a set of conditions to reproduce. If water temp is to low or to high then they just do not reproduce. if the streams and lakes dry up, they die. If water gets to salty or not enough it can change their reproduction process. Aquarium fish are the same way. Read up on breeding aquarium fish for insight.
