Fishing in lake Titicaca is from totora reed boats, using barrage nets (some knitted from llama wool), underwater nets and hand-knitted straw nets. Today fishing continues to be important to lakeshore families and on market days they sell their fish in the cities of Puno, Juliaca and smaller towns' weekly markets. Agriculture is mostly self-sufficiency farming; sometimes some inhabitants take their produce to Sunday markets (K'atos) to barter (trueque) for other products that they have not produced in the current agricultural season.
