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 ...
Importance of reservoir tributaries to spawning of migratory fish in the upper parana river
(Wiley-Blackwell, 2015)
Female Growth and Offspring Quality over Successive Spawnings in a Caridean Shrimp Neocaridina davidi (Decapoda, Atyidae) with Direct Development
(Marine Biological Laboratory, 2015-12)
This study analyzed the quality of recently spawned eggs and of juveniles over five and six consecutive spawns, respectively, in a caridean shrimp Neocaridina davidi with direct development. The potential energetic antagonism ...

Gonadal maturation in captivity and hormone-induced spawning of the Pacific red snapper Lutjanus peru
(Aquaculture, 2004)
Wild broodstock of the Pacific red snapper Lutjanus peru, a high value commercial species in Mexico, were brought to the laboratory to achieve experimentally induced gonadal maturation. Mature individuals were successfully ...
Moments of induced spawning and embryonic development of Brycon amazonicus (Teleostei, Characidae)
(Cambridge Univ Press, 2014-11-01)
Based on the economic and ecological relevance of Brycon amazonicus, the goal of this work was to describe the diameter of oocytes and eggs of this species, as well as the chronological embryonic development. The material ...
Colossoma macropomum females can reproduce more than once in the same reproductive period
(2018-09-01)
The aim of the present study was to evaluate induced reproduction in Colossoma macropomum females at the beginning of the reproductive period and 75 days after the first spawning in which reproduction was induced. The ...
Utilities of larval densities of Pacific mackerel (Scomber japonicus) off California, USA and west coast of Mexico from 1951 to 2008, as spawning biomass indices
(Ciencia Pesquera, 2010)
Fish larval densities are frequently used as an index of spawning biomass. Three time series of larval densities of Pacific mackerel (Scomber japonicus) per 10 m2 were estimated from 1951 to 2008 based on data collected ...
Aloe vera bathing improved physical and humoral protection in breeding stock after induced spawning in matrinxa (Brycon amazonicus)
(Elsevier B.V., 2015-07-01)
In this study, we show that induced spawning causes stress, an intense loss of epithelia and immunosuppression, decreasing physical and humoral protection in fish, effects that were prevented or improved in fish bathed ...
