1. Proposal for an experimental crab fishery in Subarea 48.3

   Abstract:  An experimental management strategy is proposed for the Paralomis spinosissima fishery around South Georgia. The strategy is designed to answer specific, a priori questions about the population dynamics of P. spinosissima, and consists of three phases to be conducted over a period of two

2. Using production models to assess the stock of Paralomis spinosissima around South Georgia Island

   Abstract:  Four production models were fit to a time series of daily catch per unit effort (CPUE) data from the 1991/92 fishery for Paralomis spinosissima around South Georgia Island. The four models considered recruitment in different ways. Model 1 contained a linear recruitment function; Model 2

3. Variations in the diet composition and feeding intensity of mackerel icefish (Champsocephalus gunnari) at South Georgia (Antarctic)

   Abstract:  The diet composition and feeding intensity of mackerel icefish (Champsocephalus gunnari) around Shag Rocks and the mainland of South Georgia was analyzed from c. 8,700 stomachs collected in January/February 1985, January/February 1991 and January 1992. Main prey items were krill

4. On the taxonomy of the Lepidonotothen squamifrons group (Pisces, Perciformes, Notothenioidei)

   Abstract:  The Lepidonotothen squamifrons group has been described to be comprised of 3 species: L squamifrons (Günther, 1880). L kempi (Norman, 1937) and L macrophthalma (Norman, 1937). All 3 species closely resemble each other and morphological and meristic characters utilized to distinguish

5. Timescale of ovarian maturation in Notothenia coriiceps (Richardson); evidence for a prolonged adolescent phase

   Abstract:  Ovarian maturation in Notothenia coriiceps is known to include a period during which yolk deposition begins to take place. This 'adolescent' phase was thought originally to last for about one year. The results from a two year study at Signy Island indicate that this adolescent

8. Revision of the commercial catch at age of the Antarctic icefish Champsocephalus gunnari over the period 1976/77 to 1990/91

   Abstract:  A revision of the calculation of total international catch at age of Champsocephalus gunnari over the period 1976/77 to 1990/91 is presented. This uses iterative application of two age length keys to obtain age distributions, according to a method described by Kimura and Chikuni (1987).
