This table provides metadata for the actual indicator available from Ghana statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from Ghana statistics, this table should be consulted for information on national methodology and other Ghana-specific metadata information.

| Target |
Target 14.4: By 2020, effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics |

| Definition and concepts |
Definition: Maximum Sustainable Yield (MSY) is commonly defined as the greatest average amount of catch that can be harvested in the long-term from a stock under constant and current environmental conditions (e.g., habitat, water conditions, species composition and interactions, and anything that could affect birth, growth, or death rates of the stock), without affecting the long-term productivity of the stock. MSY-based reference points are the most common type of reference points used in fisheries management today. A population is: “A group of individuals of the same species living in the same area at the same time and sharing a common gene pool, with little or no immigration or emigration.” A biological stock is: “A subpopulation of a species inhabiting a particular geographic area, having similar biological characteristics (e.g. growth, reproduction, mortality) and negligible genetic mixing with other adjacent subpopulations of the same species." |

| Rationale |
The indicator has a peculiar nature compared to more conventional SDG indicators. The indicator estimates the sustainability of fish stocks that often move across national boundaries. As a result, national data alone cannot be meaningfully aggregated at global/regional levels, but it can be used to inform country progress on fish stock sustainability within the Exclusive Economic Zone (EEZ). |
