Induction of ovarian maturation and spawning by combined treatment of serotonin and a dopamine antagonist, spiperone in Litopenaeus stylirostris and Litopenaeus vannamei
(Universidad Nacional, Costa Rica, 2004)
The study was designed to develop a reliable technique for inducing ovarian maturation and
spawning in Litopenaeus stylirostris and Litopenaeus vannamei, as an alternative to the traditional
and destructive eyestalk ...

(Universidad Nacional, Costa Rica, 1991-01-01)
En una población natural de güísaro (Psidium guineense), en Barva de Heredia, se estudió el desarrollo de las agallas de las ramas y la fenología de cuatro especies de micro himenópteros emergidos de ellas, desde abril de ...
Identification of the variant Ala335Val of MED25 as responsible for CMT2B2: molecular data, functional studies of the SH3 recognition motif and correlation between wild-type MED25 and PMP22 RNA levels in CMT1A animal models
(Springer, 2009)
Charcot-Marie-Tooth (CMT) disease is a clinically and genetically heterogeneous disorder. All mendelian patterns of inheritance have been described. We identified a homozygous p.A335V mutation in the MED25 gene in an ...
Horizontal transport and seasonal distribution of nutrients, dissolved oxygen and chlorophyll-a in the Gulf of Nicoya, Costa Rica: a tropical estuary
(Elsevier, 2002)
The distributions of salinity, temperature, nutrients, dissolved oxygen and chlorophyll-a (chl-a) concentrations in the
Gulf of Nicoya, Costa Rica, during the rainy and dry seasons are presented. In the rainy season, the ...
Induced spawning and larval rearing of spotted rose snapper, Lutjanus guttatus, at the Marine Biology Station, Puntarenas, Costa Rica
(Universidad Autónoma de Baja California, 2008)
Wild spotted rose snapper, Lutjanus guttatus (n = 400, 60–100 g), were captured and grown out in cages during one year
(February 2001 to February 2002). When the mature stage was detected by cannula samples, females (n = ...
In vitro manipulation of egg activation in the open thelycum shrimp Litopenaeus
(Elsevier, 2007)
This research was designed to develop a basis for the in vitro manipulation of egg activation in Litopenaeus. The timing and
sequence of events associated with egg activation of three species of Litopenaeus: L. occidentalis, ...
Hábitos alimentarios del pargo mancha Lutjanus guttatus (Pisces: Lutjanidae) en el Golfo de Nicoya, Costa Rica
(Universidad de Costa Rica, 1996)
A total of 504 "Spotted Snapper" Lutjanus guttatus were collected monthly in the Gulf of Nicoya, Costa Rica, from January 1993 to January 1994 to determine its feeding habits. The fishes studied ranged 12-620 cm in total ...
Growth, feed utilization and nutrient digestibility in tilapia fingerlings (Oreochromis aureus Steindachner) fed diets containing bacteria-treated coffee pulp
(Universidad Nacional, Costa Rica, 2002)
The effectiveness of bacteria treated-coffee pulp (BT-CoP) in fish diets was evaluated in a feeding trial with Oreochromis aureus (Steindachner) fingerlings. Five diets were formulated to contain 0%, 6%, 12%, 18% and 24% ...
Growth performance of Colossoma macropomum (Cuvier) juveniles at different feed rations
(Wiley & Sons, 1992)
Growth performance, feed utilization and changes in body composition of Colossoma
macropomum (Cuvier) juveniles — in the weight range 2 to 200 g — fed an artificial high protein
diet, have been analysed against feed ...
Growth and photosynthetic performance of five tree seedlings species in response to natural light regimes from the Central Pacific of Costa Rica
(Universidad de Costa Rica, 2013)
Growth and photosynthetic performance of five seedlings of tree species in response to natural light regimes in the Central Pacific of Costa Rica. Environmental heterogeneity mostly dominated by differing light regimes ...
