One of the top producing countries worldwide is the Philippines with fisheries total volume production of 4.65 million metric tonnes of a total value of US$7.26 billion in 2015. The total fish production is comprised with 1.01 million metric tonnes or 21.7% in municipal fisheries, 1.03 million metric tonnes or 23.3% in commercial fisheries, 204,733.99 metric tonnes or 4.4% in inland capture fisheries and 2.35 million metric tonnes in aquaculture. It's country's one of the top export commodities is tuna with a volume of 97, 815 metric tonnes in fresh/chilled/ frozen/ dried/canned and smoked products with an equivalent value of US$231 million. The three major export commodities are tuna, seaweeds and shrimp/prawn accounted for 63% of the total export volume and 58% of the total export value of US$909 million while it's fishery imports came from China, Vietnam, Papua New Guinea, Taiwan, Korea, Japan, USA, Norway, Indonesia, Denmark and other countries on fish, prawn feeds as well as flour, meals and pellets of fish, crustaceans and mollusks that have the value of US$275 million (BAS, 2015).
The present challenges that the Philippines fisheries facing right now are overfishing, illegal fishing, imminent threats from climate change, habitat destruction, increased demand of fish and population growth and pollution. To resolve these issues, the Philippine government must take in action on the fisheries and coastal resource management to prioritize and ensure food security measures for continued economic benefits from the rich coastal habitats and develop ecosystem-based fisheries management program to treat on coastal resources and fisheries.
The contribution of Fisheries is often more in the area of employment for individuals who are less employable than the average worker. See p.225 of:

I have a related article: Wright, C.S. 1990. Is Poverty in Fishing Communities a Tragic Process or a Matter of Choice? The 5th Conference of IIFET. 3-6 Dec/90. Santiago, Chile.
The key point is that fisheries allow communities to exist and if fisheries fail, entire communities become desolate.
P. Copes did studies on fishing communities in Newfoundland Canada -- When the fishery dies people move themselves and often their houses to larger communities -- thus fisheries provide food and the dignity of remunerative work.
My study showed that the pecuniary poverty of fishing communities was offset by a high quality of life. Good luck in your studies.
Fishing communities inhabitants are prone to migration when resources cannit sustain them anymore. This will continue if issues such as best fishing practices for sustainability are not addressed.
People often believe that fish species can never finish, because it is a renewable resource. This is true but if not properly managed, resources can be depleted.
My experience since completing my PhD in Fisheries Management and Accounting Systems under Prof Parzival Copes, is that fisheries management often does more harm than good and can diminish or even destroy fishing communities. Africa currently has a serious issue with distant water fleets -- particularly those of China.
