Đánh giá hiện trạng bảo quản sản phẩm thủy sản trên tàu nghề lưới chụp của tỉnh Lâm Đồng

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)%.
