Autores: Fraga, I.; Galindo, J.; de Arazoza, M.; Sanchez, A.; Jaime Ceballos, B.; Alvarez, S.
Para evaluar el efecto de diferentes niveles de proteína y densidades de siembra sobre el crecimiento de juveniles de camarón Litopaneus schmitti, se desarrolló un diseño experimental totalmente aleatorizado en estanque de tierra durante 72 días, con 16 tratamientos y 3 repeticiones, combinando tres niveles de proteína alimentar para definir la contribución del alimento natural al crecimiento de los camarones. La contribución del alimento natural al crecimiento fue entre 58.2 - 87.9% y los copépodos constituyeron el 65% del total de organismos del zoobentos. Una alta correlación negativa se encontró entre la cantidad de organismos epibentónicos y las densidades de siembra ensayadas.

Autores: Ehrlich, M.D.; Macchi, G.J.
Hake Merluccius hubbsi fecundity was estimated with the gravimetric method using ovaries with hydrated oocytes without post-ovulatory follicles. Samples were obtained in three research cruises in the Argentine Sea, off Chubut Province, SW of Peninsula Valdes between 42°S and 45°S, near Isla Escondida, during December 1993, 1994 and 1996, time which coincides with the most important reproductive activity. Relative fecundity values were 722 plus or minus 107, 606 plus or minus 60 and 533 plus or minus 26 oocytes per gram of female without ovaries, respectively. Partial fecundity was adjusted to a potential model for total length and weight without ovaries, corresponding: F=0.9988 Lt3.294 and F=197.91 P1.1585 for 1994 and F=6.9785 Lt2.816 and F=552.22 P0.9889...

Autores: Dato, C.V.; Villarino, M.F.; Cañete, G.R.
To improve the quality of the resource assessment it is necessary to estimate discards and quantify them applying an adequate methodology. The purpose of this work is to detect areas where the activity of the commercial fleet coincides with zones of high concentration of juveniles because they are potential discard areas. To establish possible seasonal and/or interannual variations, length distribution data derived from hake research surveys carried out on board of INIDEP vessels during the 1986-1993 period were analyzed. Samples were grouped per statistical rectangle on the basis of catch weighted average and mean, variance, skewness and kurtosis were calculated. The resulting parameters were subjected to a cluster analysis using the Euclidean distance...

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Jaime Ceballos, B. J.; Fraga Castro, I.; Galindo López, J.; Alvarez Capote, J.S.
This study determined the effect of different shrimp head meal (SHM) levels (0, 5, 15, 25 and 30%) in practical diets for Caribbean white shrimp juveniles Litopenaeus schmitti (0.29 ± 0.0025 g). A totally randomized experimental design was carried out under laboratory conditions during 54 days. There were no significant differences (p &gt; 0.05) in survival of shrimps in all treatments evaluated. This result indicated that SHM included at 5, 15 and 25% in diet promoted growth. The relation of SHM inclusion level in diet with final weight (FW), food conversion rate (FCR) and protein efficiency ratio (PER) were described by the following quadratic equation: FW = 0.8023 + 0.0604 S - 0.0018 S2, 2 =0.81; FCR = 8.0019 - 0.6081 S + 0.0164 S2, R2 =0.82 and PER =...

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: López, A.C.; García, C.B.
Postlarvae and juveniles of Farfantepenaeus spp. and Xiphopenaeus kroyeri were collected at Boca de la Barra (Ciénaga Grande de Santa Marta), by means of a channel net that orientates with the tide. Sampling was carried out every two weeks for ayear (February 1998 – February 1999), so that each sampling date corresponded to full and new moon alternatively. Farfantepenaeus spp. postlarvae tended to appear in the dry season and with significantly greater abundance during full moon (Mann-Whitney test, P&lt;0.05). Juveniles showed a different pattern: there were significant differences between seasons (Mann-Whitney test, P&lt; 0.05) with higher concentrations in the rainy season, but not so between moon phases (Mann-Whitney test, P&gt;0.05). In the case of X....

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Santos, B.A.; Renzi, M.A.
Growth of hake (Merluccius hubbsi) in the 0-group from the Argentine-Uruguayan Common Fishing Zone was studied and spawning data were back-calculated by identifying daily growth rings in otoliths of specimens caught during research cruises performed in May 1997, May 1998 and June 1999. Total length (TL) range was 14-69 mm. Increments were read under microscope using an otolith daily ring measurement system (RATOC). Changes in the increment width data present a pattern that seemed to be similar, and independent from birth date of individuals. Data observed and back-calculated showed good accordance with the Laird-Gompertz model. Significant differences between coefficients were found in all comparisons of growth curves for observed and retrocalculated data....
