“…Growth appears to be fastest during autumn at both localities, but the magnitude of the seasonal difference is greater at Peraki Bay. Seasonal differences in growth rate have been recorded for other haliotids (Cox 1962;Sakai 1962;Leighton & Boolootian 1963;Forster 1967;Newman 1968) and for 2 species the magnitude of the seasonal difference appears similar to that found for H. iris at Peraki Bay. Forster (1967) found that H. tuberculata grew about 70% of their annual increment in a single autumn month and Cox (1962) reported that almost the entire annual increment of H. rufescens was attained during the winter.…”

The biology of an unfished population of the paua, Haliotis iris Martyn, in Peraki Bay, Banks Peninsula, was studied from 1973 to 1976. In February 1976 the population consisted of about 179 000 animals on 4.5 km of coastline. The length/frequency distribution was strongly skewed to the left, indicating an accumulation of old individuals and a recent history of low recruitment. Growth of animals <70 mm long was determined from changes in length frequency, and of larger animals by the analysis of tag returns. The mean parameters of the von Bertalanffy growth equation for the study population are K = 0.163 and L = 131.9 mm. Both are lower than those reported for paua in a more typical habitat near Kaikoura. The annual instantaneous natural mortality rate, as estimated by several methods from population size structure and individual growth rate data, is about 0.1. Spawning was monitored during the breeding seasons of 4 years. Spawning on Banks Peninsula failed to occur during 2 years, and the failure during 1 year was geographically widespread. No explanation for these spawning failures can be offered. The length at first maturity was the same at Peraki Bay and Kaikoura, despite a much lower growth rate and fecundity at Peraki Bay. Recruitment was 2000-5000 2-year-olds per year and either recruitment is largely independent of local spawning success or significant spawning occurs outside the currently accepted breeding season.

“…Variability of growth parameters between localities has been demonstrated for many other haliotids (Leighton & Boolootian 1963;Forster 1967;Poore 1972a;Shepherd & Laws 1974). Shepherd & Laws (1974) reported that both H. ruber and H. laevigata grew faster in exposed areas than sheltered areas.…”

“…The abundance of black abalone at each site was estimated as the total number of individuals found in all 3 plots. To determine whether the decline of black abalone was dependent on their size, individuals were placed into 4 categories based on their maximal shell lengths: (1) < 50 mm or juveniles (see Leighton & Boolootian 1963); (2) 50 to 90 mm or small adults; (3) 91 to 126 mm or large adults; and (4) >126 mm or harvestable adults, although recreational (individuals >126 mm) and commercial (individuals >145 mm) harvesting of black abalone was banned throughout California in 1993. Linear regression analyses of abalone number (trans- formed to their natural logarithms) versus time for juveniles, small adults, large plus harvestable adults, and all size categories together were used to assess increases or decreases in the population abundance at each site.…”

Production of Calcium Carbonate on the Mainland Shelf of Southern California1

Although calcareous organisms are abundant on hard‐bottom portions of the southern California mainland shelf, negligible amounts of CaCO3 are accumulating there. Data collected at three localities and 22 stations along the southern California coastline give subtidal rates of CaCO3 production by calcareous organisms, from turnover rates calculated from growth rate data, from mortality calculations based on size distribution and growth data, and from miscellaneous information, near 400 g CaCO3 m‒2 yr‒1. Although this temperate climate production rate is lower than rates of coral reef production, it is similar to tropical nonreef production rates and much higher than pelagic production rates of CaCO3. The CaCO3 produced is lost from the mainland shelf, probably by transportation to adjacent basins, and then is apparently in large part dissolved. About 4 × 1010 g CaCO3 yr‒1 are produced across 103 km2 of the shallow hard‐bottom shelf areas of southern California and subsequently removed from those areas.
