Assessment of the preservation status of seafood products on falling-net fishing boats in Lam Dong province
Abstract
The article presents the results of an assessment of the status of product preservation on the falling-net boats in Lam Dong province by two methods: interviewing fishermen (30 samples) and directly surveying on the boats (30 samples) by pre-designed questionnaires and the FAO’s product classification method (1995). The results showed that the average length of the boat was (21.2 ± 3.6) m, and the average capacity of the main engine was (536.4 ± 213.8) CV. The main insulation material of the storage hold was foam (77.8%), with an average volume of (17.0 ± 7.8) m³, and a capacity of (5.8 ± 3.0) tons/hold; all boats used plastic trays and PE bags to contain products, someones you morecombined plastic barrels or tin trays. All vessels 100% employed the preservation method using crushed ice, among which 55.6% additionally applied freezing and 55,6% cold storage. The proportion of type A products ranged from 10.0 ÷ 100.0%, with an average of (46.9 ± 23.0)%; the value of type B was 1.8 times higher than that of type C, type C was 1.5 times higher than that of type D, and type D had a lower value than that of type A on average (34.5 ± 17.7)%.
