Changes in Volume, Biomass, and Fatty Acids of Developing Eggs in Nauticaris Magellanica (Decapoda: Caridea): A Latitudinal Comparison
A latitudinal cline in egg volume in N. magellanica is confirmed, and the lipid biochemistry of developing eggs seems to be unaffected by latitude.
Lipid composition and utilization in developing eggs of two tropical marine caridean shrimps (Decapoda: Caridea: Alpheidae, Palaemonidae)
Changes in biomass and lipid biochemistry during egg development were studied in the tropical shrimps, Alpheus saxidomus and Palaemonetes schmitti, from Pacific Costa Rica to indicate an enhanced independence of the newly-hatched larvae on external energy resources.
Distribution and reproduction of ambidexter panamense and palaemonetes schmitti in pacific costa rica (crustacea, decapoda)
Este constituye el primer registro de las especies de carideos P. schmilli y A. panamense para Costa Rica y fue el camaron mas abundante en el estero de Punta Morales, Golfo de Nicoya.
Reproductive Biology of the Freshwater Shrimp Macrobrachium carcinus (L.) (Decapoda: Palaemonidae) from Costa Rica, Central America
Abstract Macrobrachium carcinus, one of the largest freshwater shrimp of the east coast of the Americas, is commercially fished in certain parts of the region. We present data concerning the
Feeding ecology of common demersal elasmobranch species in the Pacific coast of Costa Rica inferred from stable isotope and stomach content analyses
Season had little influence on elasmobranch diet, but data suggested thatotopic baseline values differ between geographical regions, suggestingerences in local bio- geochemical processes and/or prey availability, and possibly in response to seasonal nutrient fluctuations.
Species composition and distribution of decapod crustaceans in the waters off Patagonia and Tierra del Fuego, South America
SUMMARY: This paper comprises the decapod crustacean material collected during the “Victor Hensen” campaign 1994 and during the last phase of “Polarstern” cruise ANT XIII/4 in 1996. Sampling covered
Egg production in Betaeus emarginatus (H. Milne Edwards, 1837) (Decapoda: Alpheidae): fecundily, reproductive output and chemical composition of eggs
The snapping shrimp Betaeus emarginatus from central-southern Chile produced numerous and relatively large eggs, which more than double in volume during embryogenesis and corroborate the tendency of decreasing RO with increasing latitude.
Lipid and fatty acid composition of Antarctic shrimp eggs (Decapoda: Caridea)
It is assumed that eggs produced by polar decapod crustaceans do not contain substantially more lipids than related species from temperate or tropical regions, however, additional studies are necessary to substantiate any general conclusion about the relationship of egg lipid content and composition with climatic zones.
Interpopulation Comparison of Reproduction of the Atlantic Shrimp Hippolyte obliquimanus (Caridea: Hippolytidae)
The reproductive traits of both populations of H. obliquimanus show some important differences which may reflect adaptations to local environmental conditions, demonstrating a high plasticity of reproductive features of the species in Brazilian and Costa Rican waters.
