Mesopelagic Zone
    Also called the 'twilight zone' of the ocean, this area from 200m to 1000m in depth, is bordered by the photic zone above and darkness below. It's in this zone where you start to see bioluminescence on all sorts of animals. Visit the Mesopelagic Zone on OceanLink to learn about the animals unique to these depths.
MFMT
    Maximum Fishing Mortality Threshold - the level or rate of fishing mortality, that if exceeded, will result in overfishing and jeopardize the capacity of a stock or stock complex to produce maximum sustainable yield on a continuing basis.
Microsatellite loci
    Variable numbers of short tandem DNA repeats.
Microstomus pacificus
    Dover Sole
Milt
    The milky sperm the male salmon releases to fertilize the eggs

MLLW
    Mean Low Low Water
Morphology
    The form and structure of an organism, in particular its outside features.
MSP
    Maximum Spawning Potential - see SPR.
MSST
    Minimum Stock Size Threshold - the minimum size of the stock or stock complex that is required to produce maximum sustainable yield (MSY), below which the stock would be considered overfished. The threshold should equal whichever of the following is greater: half the MSY stock size, or the minimum stock size at which rebuilding to the MSY level would be expected to occur within 10 years if the stock or stock were exploited at the maximum fishing mortality threshold.
MSY
    Maximum Sustainable Yield - the largest long-term average catch or yield that can be taken from a stock or stock complex under prevailing ecological and environmental conditions.
mtDNA
