State of the World’s Fisheries
▪ Abstract The total world catch from marine and freshwater wild stocks has peaked and may be slightly declining. There appear to be few significant resources to be developed, and the majority of the
Precaution in the harvest of Methuselah's clams the difficulty of getting timely feedback from slow-paced dynamics
TLDR
Geoduck (Panopea abrupta) stocks are perceived as stable and their fisheries as sustainable, but this may reflect a mismatch between slow-paced dynamics and short-term perception, which could accelerate population declines and drive an apparently sustainable fishery to collapse.

Patterns and Processes of Chasmagnathus granulata and Cyrtograpsus angulatus (Brachyura: Grapsidae) Recruitment in Mar Chiquita Coastal Lagoon, Argentina
TLDR
This work compares the recruitment pattern of Cyrtograpsus angulatus and Chasmagnathus granulata on the basis of a 3-year sampling programme, and proposes a qualitative model of recruitment of each species.
Zygochlamys patagonica beds on the Argentinian shelf. Part I: Energy flow through the scallop bed community
TLDR
The scallop bank, “Reclutas”, on the Argentinian shelf was sampled on two occasions, first, somemonths after initial settlement of the scallip Zygochlamys patagonica (1995) and again, 4 years later (1998), when the proportion of Z. patagonicas rose to > 60 % for both.

Length at maturity of the greeneye spurdog shark, Squalus mitsukurii (Elasmobranchii : Squalidae), from the SW Atlantic, with comparisons with other regions
TLDR
Evidence is added of the plasticity of S. mitsukurii in size at maturity among the SW Atlantic squalid sharks as well as the length–weight relationship, which did not differ between sexes in the SWAtlantic population, whereas it differed in one population from the NW Pacific.
Feeding habits and prey selection by the skate Dipturus chilensis (Elasmobranchii: Rajidae) from the south-western Atlantic
The diet of Dipturus chilensis was composed mainly of the nototheniid fish Patagonotothen ramsayi, squid Illex argentinus, hake Merluccius hubbsi, serolid isopods, and crustaceans. Our results
