Embryonic, early larval development time, hatching mechanism and interbrood period of the sac-spawning euphausiid Nyctiphanes simplex Hansen
(Journal of Plankton Reseach, 2005)
Females of the sac-spawning euphausiid Nyctiphanes simplex Hansen were incubated under shipboard laboratory conditions to observe the embryonic and larval development time and hatching mechanism. Females ready to spawn ...

(Sociedade Brasileira de Zoologia, 1999-01-01)
This study analyses some reproductive aspects of Portunus spinimanus Latreille, 1819, a crab usually commercialized in Ubatuba region. Monthly otter-trawl collections were taken for two years along the northern coast of ...
Dynamics of the Confluence of Malvinas and Brazil currents, and a southern Patagonian spawning ground, explain recruitment fluctuations of the main stock of Illex argentinus
(Wiley Blackwell Publishing, Inc, 2020-09)
The Argentine shortfin squid (Illex argentinus) sustains one of the world's largest squid fisheries. This squid presents strong interannual fluctuations in abundance, attributed to its semelparous life strategy coupled ...
Spatial patterns of copepod biodiversity in relation to a tidal front system in the main spawning and nursery area of the Argentine hake Merluccius hubbsi
(Elsevier Science, 2014-08)
Copepods play an important role in marine ecosystems as a direct link of energy transfer between primary producers and higher trophic level consumers, such as fish. In the Argentine Sea, the Patagonian stock of Argentine ...
Tracking larvae with molecular markers reveals high relatedness and early seasonal recruitment success in a partially spawning marine bivalve
(Berlin, 2015)
The partial synchronized spawning strategy
adopted by some marine invertebrate broadcast-spawners
can lead to the production of many distinct pools of larvae
within a single reproductive cycle. Following the fate of
these ...
Biology of the subtropical sac-spawning euphausiid Nyctiphanes simplex in the northwestern seas of Mexico: Interbrood period, gonad development and lipid content
(Deep-Sea Research Part II: Topical Studies in Oceanography, 2010)
Interbrood period, gonad development, and total lipid content throughout the oogenesis and spermatogenesis processes of the subtropical euphausiid Nyctiphanes simplex were studied. Specimens were collected during six ...
