The distribution, relative abundance, and population structure of Haliporoides diomedeae was determined off northern Perú (3º30’S-10º00’S) by analyzing data from two cruises carried out in 2007 and 2008 on board the B/O Miguel Oliver to assess the bentho-demersal fauna between 200 and 1,500 m depth, using a stratified random bottom trawl design. The total catch from the 122 hauls (covering four sectors and three strata) was 48,056 kg, with ~347 fish and invertebrate species. H. diomedeae was the most important shrimp in the catches (411 kg), with the highest abundance levels between 600 and 1,600 m depth north of 7º00’S. The mean catch per unit area (CPUA) was between 83.4 and 211 kg km-2. The total biomass was estimated to be 1,139.74 ton (± 245.6 ton). The mean carapace length of the females was 40.6 mm, with a range of 14.5 to 74.5 mm and a main modal group of 30 mm; the mean carapace length of the males was 30.6 mm, with a range of 16 to 63 mm and a main modal group of 27 mm. Males and females showed six modal groups, sexual dimorphism, and a bathymetric gradient. The length-weight relationship was allometric. Given the distribution, abundance, and size structure of H. diomedeae off the northern Peruvian coast, it can be considered a potentially exploitable species in the sea off northern Perú.
