The life of people from Klenovica has always been connected to the sea. In the past, they mainly made their living from fishing and seafaring, along with masonry and animal husbandry, until the 1960s. This was due to the configuration of the terrain and the occasional springs of fresh water in the sea (the most famous are in Žrnovnica Cove), which favour the development of flora and fauna, making the zone rich in fish. Tuna fishing was the most important fishing activity in this area until 1963, when tuna gill nets were put out of use. Tuna was salted in the hinterland – in Ledenice, Breze, Bribir and Zabukovac – and was an important source of food in the diet of people in this area. The first fishermen from Klenovica went fishing at night using wood-fired lights. In 1910, after returning from America, the stonemason Franjo Cvitković and his brother Ivo bought a large fishing boat, two small fishing light boats, a drag net and other tools, and in 1920 founded the Udarnik fishing cooperative, which marked the beginning of modern fishing in Klenovica. Following innovations and new technologies in fishing, in 1936 a purse seine net was procured, the best net for catching sprats and mackerel, made in 1909 by the well-known Crikvenica entrepreneur and fisherman Ivan Skomerža. It is remembered that in the autumn of 1943, as many as 4,000 tuna weighing 3-5 kg were caught, or a total of 15,000 kg, which was considered a record catch. The first motorboat, the Lidija, was purchased when the Udarnik cooperative was founded. This was followed by the Jablanac (later the Zlatac) in 1947, the Lastovo (later the Oliga), the Iglun in 1956, the Iverak in 1966, and the Bentos. Over time, ships were equipped with echosounders and new nets and devices. In 1970, the ship Osoršćica was purchased, followed by the Nautica in 1977. This was a time when open sea fishing was increasing, and the catch per ship amounted to around 50 wagonfuls! The fishermen of Klenovica were awarded the Vjesnik Blue Ribbon for rescuing 17 people in the Velebit Channel in the night between 4 and 5 July 1982, and for many other acts of rescuing people and property at sea in bad weather. The monument to the fisherman in the centre of Klenovica, modelled on the figure of the fisherman Nikica Cvitković, who became a local legend in his lifetime, also reminds us of the brave deeds of fishermen from this area.
Jugoistočna punta uvale Žrnovnice upola je niža i zelenija od gole suprotne. Po njenoj sredini već počinju vikendaške gradnje mjesta Klenovice. U slabo zaštićenoj valici Klenovice, i danas najribarskijeg mjesta na ovom dijelu obale, uvijek je vezano nekoliko plivarica. One zauzimaju neveliki pristan pod sjevernom obalom luke.
