“…However, during the t ime of hormonal treat ment it was possible to observe in general a lower condition factor in the fish of the EE 2 -treated groups compared to the fish of the control group. Hoque et al (1998) mention that this decrease could be interpreted as depletion of energy reserves stored as liver g lycogen or body fat. A reduction in food intake could provoke such effect, especially at early stages of development.…”

Production of YY-males is one of the most important alternatives to the commercial use of hormones for producing monosex populations in the culture of Nile tilapia. One of the final stages of YY-technology is the feminization of the progeny of XY-females in order to obtain YY-females, which when crossed with YY-males makes possible to obtain populations composed of 100% YY-males. The aim of the study was to evaluate the effects of four concentrations (100, 200, 300, 400 mg kg -1 ) of estrogen 17α-ethinylestradiol (EE 2 ) on the sex ratio, growth, condition factor (CV) and gonadosomatic index (GSI) of the progeny of XY-females. Significant differences were observed in wet weight, total length and CV during the experiment; however, final values in EE 2 -treated groups showed not significant differences with control group. The observed proportion of females deviated significantly from the proportion of females expected in the progeny of XY-females in all groups fed EE 2 ; however, only 90% feminization was attained. The group fed 200 mg kg -1 of EE 2 showed a significantly higher value of GSI in comparison to that observed in the control group. By increasing the concentration of EE 2 it is possible to increase the proportion of females without affecting growth or GSI.

“…The condition factor also can be used to assess physiological status under a potential stressor (Hoque, Yusoff, Law, & Syed, 1998) such as a feeding fry with a synthetic estrogen. In our work, condition factor was highly variable during the fry period and init ial stages of the juvenile period (41 d of age).…”

“…Hepatosomatic index (HSI) of the liver is a considerable potential tool used by fish biologists to assess the toxicity situation of the exposure of fish to any toxicant as well as a management tool for evaluating growth or health status of various fish species in different environments (Hoque et al, 1998). The increase in HSI value in an ideal environment is related to normal liver growth but, in cases of pollution, liver enlargement is associated with hyperplasia (Hoque et al, 1998 Histopathological observations on C. gariepinus fed graded levels of BSSM diets Examination of the liver, kidney and intestine was done because of their physiological importance during absorption and metabolism of chemicals (Roberts, 1989). Evaluation of histological structure of digestive organs in fish fed new dietary ingredients generates valuable information about their digestive capacity and the potential health effects of such diets (Diaz et al, 2006).…”

This study investigated the effects of substituting boiled sunflower seed meal (BSSM) for soybean meal (SBM) on the organosomatic indices and histopathological changes in the liver, kidney and intestine of Clarias gariepinus juveniles for fifteen weeks. BSSM was substituted for SBM at 0, 20, 40, 60, 80 and 100% in formulating six isonitrogenous (40% crude protein) and isocaloric (4651.5 Kcal/kg) diets. Diets were fed twice daily to triplicate groups of 360 C. gariepinus juveniles inside eighteen rectangular tanks (20 fish per tank). The result showed that hepatosomatic index (HSI) was significantly highest (3.11%) in the fish fed 0% BSSM diet and lowest (0.87%) in those fed 100% BSSM inclusion. HSI values progressively decreased with increasing inclusion level of BSSM. Kidney-somatic index (KSI) was highest (0.74%) in fish fed 20% BSSM inclusion and least (0.32%) in those fed 100% inclusion. Intestino-somatic index (ISI) was superior (3.82%) in fish fed 100% BSSM inclusion and least (3.16%) in those fed 40%. The liver, kidney and intestine of fish fed 0 and 20% BSSM inclusions showed no visible signs of damage. However, fish fed higher BSSM inclusions (>20%) revealed extensive hepatic degeneration, periportal congestions and severe diffuse cytoplasmic vacuolations of hepatocytes. Kidney tubules of fish fed higher BSSM inclusions exhibited diffuse interstitial congestions, diffuse swelling, epithelial vacuolations and degeneration as well as necrosis. Intestinal changes in fish fed higher BSSM inclusions included reduced sub-mucosal width, markedly stunted villi, moderate erosion of villi's epithelia, hyperplastic villi, necrosis of enterocytes and inflammatory cells in villi's lamina propria. Inclusion of boiled sunflower seed meal beyond 20% in C. gariepinus' diet could cause adverse histological alterations.

“…La composición química de diferentes tejidos puede variar considerablemente, especialmente en el contenido de lípidos y agua (Haug 1990). Durante períodos de alta ingesta los lípidos pueden ser almacenados en el tejido somático y el hígado, así como en torno a las vísceras (Hoque et al 1998, Collins & Anderson 1995, por lo que los lípidos pueden ser usados como marcadores de condición, ya que pueden mostrar períodos de ciclos anuales asociados con cambios en las condiciones de los peces (Shulman & Love 1999). Existirían cambios estacionales en la composición de lípidos, agua y proteínas en músculos, hígado y vísceras, asociados a procesos de crecimiento gonadal y otros procesos asociados al desove, ya que la acumulación de lípidos depende directamente de la disponibilidad de alimento, y es muy importante en la recuperación en períodos de postdesove (Eliassen & Vahl 1982;Shulman & Love 1999).…”

RESUMENPinguipes chilensis presenta un comportamiento alimentario y reproductivo que comprende todo el año, en donde índices de condición como Indice Hepatosomático y Factor de Condición no se relacionan con la madurez de las gónadas, indicando una posible independencia de la energía almacenada como lípidos en la musculatura y en el hígado con el proceso reproductivo. El presente trabajo determina el contenido de lípidos totales (%) en la musculatura de P. chilensis, y su variación entre zonas del cuerpo, así como diferencias entre sexos y ontogenéticas. En hembras (n=12) y machos (n=11) capturados en el litoral de Talcahuano, Chile, se determinó el contenido de lípidos totales mediante la Técnica Gravimétrica de extracción por Soxhlet, de tejido muscular desde tres zonas del cuerpo, anterior, medio (con y sin tegumento) y posterior. La musculatura de hembras y machos no muestra diferencias significativas en el contenido de lípidos totales por zona del cuerpo del pez analizado (p=0,12 y p=0,24, respectivamente). En muestras agrupadas, el contenido de lípidos de la zona posterior es menor (p=0,01) al de la zona media del pez. El porcentaje de lípidos totales no se relacionó con la talla (p>0,20) y el peso (p>0,20) de los individuos, reflejando una importancia menor de la musculatura como sitio de almacenaje de lípidos o una movilización continua de lípidos totales para procesos de maduración gonadal.PALABRAS CLAVES: Lípidos, Pinguipes chilensis, Chile. ABSTRACTPinguipes chilensis presents an alimentary and reproductive pattern similar around the year. The Hepatosomatic Index and the Condition Factor are not correlated with gonad maturation as an expression of independence between store energy as lipids in muscles and liver associated with reproductive processes. In this work the percentage of total lipids in muscles of P. chilensis and body variation were determined. Also the differences between sex and ontogeny were evaluated. In fishes caught off Talcahuano, Chile (12 females and 11 males) the total lipids percentages were quantified using the Soxhlet method. Samples of muscles were taken from three parts of the body (anterior, center and posterior). The muscles present no statistical differences in lipid content between the body parts for males or females (p= 0.24 and 0.12 respectively). In pooled samples the lipid content in the posterior part is minor (p= 0.01) to the central part. The total lipid contents are not related with length (p>0.2) or weight (p>0.2) showing the muscles with less importance as lipids store or that the lipids are moved continuously for the gonad maturation.
