Imports make up a substantial and increasing portion of fish consumed in Europe and North America (about 70 percent) and Africa (about 40 percent) because of solid demand, including that for non-locally produced species, in the face of static or declining domestic fisher y production. In many developing countries fish consumption is mainly based on domestic production, and consumption is stimulated more by supply than by demand. However, with rising domestic income, emerging economies are increasing their imports to diversif y the t ypes of fish consumed. Despite trade expansion and technological advances in processing, preser vation and transportation over recent decades, fish is a highly perishable food, and supplying markets distant from where fish is caught or farmed involves significant logistical challenges and cost considerations. Beyond these supply-related issues, consumer demand may be lacking where people have not historically consumed fish in large quantities and do not have cultural and dietar y familiarit y with fish as a food group. In these markets, increasing fish consumption requires marketing and awareness raising campaigns in addition to the establishment of supply infrastructure. Although fish producers and marketers can maintain a degree of responsiveness to the evolution of consumer preferences, natural resource constraints and biological considerations are key in determining which species and products are made available to consumers. This characteristic of the fisher y and aquaculture sector is clearly ref lected in the rapid growth of the aquaculture industr y since the mid-1980s, coinciding with the relative stabilit y of capture fisheries production since the late 1980s. In parallel with the growth in aquaculture production, the share of farmed fish in human diets has increased quickly, with a milestone reached in 2013 when the aquaculture sector’s contribution to the amount of fish available for human consumption overtook that of wild-caught fish for the first time. The share of aquaculture products in total food fish consumption was 51 percent in 2015 and, according to preliminar y estimates, 53 percent in 2016, as compared with 6 percent in 1966, 14 percent in 1986 and 41 percent in 2006 (Figure 31). Aquaculture producers are able to exercise much greater control over fish production processes than capture fisheries, and the aquaculture sector is more conducive to vertical and horizontal integration in production and supply chains.
