Distribution and biomass of two squid species off southern New Zealand: Nototodarus sloanii and Moroteuthis ingens
The distribution and biomass of two species of squid, the ommastrephid arrow squid Nototodarus sloanii and the onychoteuthid squid Moroteuthis ingens, were analysed off southern New Zealand. These two species are the most important and abundant species in this region of the South Pacific Ocean. Data...

description |
The distribution and biomass of two species of squid, the ommastrephid arrow squid Nototodarus sloanii and the onychoteuthid squid Moroteuthis ingens, were analysed off southern New Zealand. These two species are the most important and abundant species in this region of the South Pacific Ocean. Data were obtained from extensive NIWA research cruises over 10 years. There was a sharp demarcation between the distribution of the two species, with N. sloanii occurring predominantly shallower than 600 m, with the greatest biomass less than 300 m. In contrast, M. ingens had the highest biomass between 650 and 700 m and occurred down to 1400 m. The biomass of N. sloanii reached more than 3500 kg km-2, with an average catch rate of over 186 kg km-2. In contrast, the biomass of M. ingens was more than an order of magnitude less, with all catch weights less than 200 kg km-2 and an average catch rate less than 17 kg km-2. The separation of these two species appeared to be related to depth, temperature and, possibly, salinity. N. sloanii occurred predominantly in warmer, shallower subtropical waters while M. ingens occurred in deeper, cooler subantarctic and antarctic intermediate water masses. The Subtropical Front formed a major barrier between the distribution of these two squid species. |
