Final answer:
Over 1/4 of all seafood is indeed produced through aquaculture, which is essential to meet the rising seafood demand as wild fisheries face overexploitation and declining yields.
Step-by-step explanation:
The statement that over 1/4 of all seafood is produced through aquaculture is true. Aquaculture, also known as fish farming, is increasingly being utilized to meet global seafood demands. This is in response to the overexploitation of marine fisheries, which has led to declining yields and concerns about the sustainability of wild fish populations. Aquaculture is identified as a significant contributor to the introduction of non-native species into various ecosystems, and while it helps to maintain the supply of seafood, it also poses environmental challenges such as water pollution and loss of wetlands.
