Резюме:
This study was based on the data from the ichthyoplankton survey made in March-April 1989 by R/V "Vozrozhdenie" in the subtropical frontal zone over the South Atlantic ridge crest between 38°30’ - 45°S. and 15° - 20°W. Larvae were collected with BONGO and JUDAY nets in oblique arid vertical hauls at 500 - 0m. The method of delta-distribution of random values (Aitchison, Brown, 1957; Pennington Read More

Резюме:
Exporatory fishing with bottom trawl conducted by the French trawler « Austral» off the Crozet archipelago (sub-area 58-6) does not allow to detect any other marine living resources than the only one Nototheniid fish Dissostichus eleginoides. The other species have no future for a commercial exploitation due to their sizes. Deep-sea fishing only (slope of the shelf :300 - 750 m) show some Read More

Резюме:
Ichthyoplankton samples were obtained during the Italian Antarctic Oceanographic Cruise carried out in the western Ross Sea in November-December 1994. The present study focused on improvement of the knowledge of the larval fish community in relation to its distribution and relative abundance. A midwater trawl (Hamburg Plankton Net) was used to collect samples at 26 stations. Larval and Read More

Резюме:
In order to avoid several problems associated with assessing the D. eleginoides stock in Subarea 48.3, it has been proposed to use the FAO programme ANACO (Mesnil, 1989) which allows one to make coefficients of fishing mortality F more precise by using catch data on age groups without resorting to additional information on effort. VPBAS files for running the programme were created using our Read More

Rossii revisited: new information on the early history of the fishery for Notothenia rossii in Subarea 48.3

New catch data reported to CCAMLR indicate that Notothenia rossii was heavily exploited in Subarea 48.3 from 1966- 197 1, rather than just 1970 and 197 1 as previously reported. Previous assessments, based on the incomplete data set, had indicated a 1970 biomass of 600 000 tonnes and an unrealistic stock history considering that this stock was the first to be exploited in the Antarctic.

The effects of an experimental hake Merluccius capensis/paradoxus longline fishery on Procellariiform seabirds in South Africa - a preliminary investigation

Due to the detrimental effect longline fisheries have had on seabirds in other parts of the world, concern was raised as to the effect an experimental Hake longline fishery would have on Procellariiform seabirds in South Africa. Carcases of Procellariiform seabirds caught on Hake longlines during setting were retrieved to determine species, sex and stomach contents. Whitechinned petrels Read More

Haul by haul Chilean and Argentinian data show that fishing forDissostichus eleginoides in 1994/95 took place in two major fishing grounds, West of Shag Rocks (Wshag) and North-West of South Georgia (NWSG). In March there was a high proportion of large females at Wshag (72%) but a nearly equal proportion of males and females at NWSG. It is suggested that a strong influx of small fish at Wshag Read More

Mean densities and length structure of Champsocephalus gunnari obttained in the 1994 and 1995 surveys conducted in subarea 48.3 by BIP Dr: E L HOLMBERG are compared. Haul locations were determined by a search procedure yielding randomly selected clusters of stations located within the 50–150; 151–250 and 251–500 m depth strata. The cluster structure is considered as a nested factor in an ANOVA Read More

The survey comprised 48 bottom trawl hauls taken in subarea 48.3. About 80% of the hauls were intended as replicates of the position of hauls in the 1994 survey, allowing site by site comparison between both cruises. Of these, 20 hauls were located at less than 0.5 miles and 11 between 0.5 and 1.0 miles from those in the previous survey. Mean densities were obtained considering the spatial Read More

About 1300 stomach contents of the icefish Champsocepha1us gunnari caught in the Subarea 48.3 in February 1995, were analyzed using the frequency of occurrence (%) method. Krill (Euphausia superba) (58%) and the amphipod hyperiid Themisto gaudichaudii (55%) occurred similarly at South Georgia and constituted the main food. At Shag Rocks, T. gaudichaudii was the main prey item (52%), followed Read More

An age-length key was prepared for Champsocephalus gunnari from the Subarea 48.3, based on the readings of otoliths collected during the R/V Holmberg survey in February 1995. Small and medium sized fish (total length 12-34 cm) predominated in the samples at South Georgia, while larger specimens (>34 cm) were scarce. Age groups 1-5 and 2-4 were well represented at South Georgia and Shag Read More

This paper presents a flexible structure for a general yield model, which provides flexibility for assessing the influence of different patterns of growth, natural mortality, spawning and fishing on the estimates of yield per recruit. Also, it can be used to evaluate the performance of a stock under a specified catch regime. The model uses an adaptive Runge-Kutta procedure to evaluate stock Read More
