Figure 2. – Principles of CMSY assessments. A: Sche- matic representation of a biomass trajectory, showing at first the limited effect of modest catches on a large biomass, then a large decline due to high, unsustain- able catches (see dotted red vertical lines in insert), not compensated any more by biomass growth, and which declines further after the catch is reduced to a lower level than previously, because the low biomass is now insufficient to sustain even such low catch levels. B: Catch of cod (Gadus morhua) from the Southern Grand Banks – Southern Newfoundland Marine Ecoregion from 1950 to 2019 used from a CMSY assessment (see # 12 in Tab. I). C: Showing the values (dark grey) of r and k, which lead to viable biomass trajectories. The blue cross (upper left) identifies the 'best' r & k pair without considering ancillary data, while the red cross (lower right) identifies the best pair when such data (CPUE data in this case) were also considered (see Table I and text). ... : Published as part of Palomares, Maria-Lourdes D. & Pauly, Daniel, 2022, The fisheries of the sea around Saint-Pierre and Miquelon: from cod to sea cucumber, pp. 337-347 in Cybium 46 (4) on page 342, DOI: 10.26028/cybium/2022-464-002, http://zenodo.org/record/12713109 ...
