“…It appears that high level cornstarch did not disrupt the digestive gland seriously. This result was not consistent with that obtained with juvenile shrimp ( P. monodon ) (Piedad‐Pascual et al 1983). Piedad‐Pascual and co‐workers suggested that the tubes of the digestive gland would be disrupted when shrimp was fed with diets containing 10% molasses and only the connective tissue capsule would be visible in some portions of the gland.…”

The ability of Litopenaeus vannamei (initial mean weight: 0.96 ± 0.02 g) to utilize different levels of cornstarch was examined in terms of growth indices, body composition, digestibility and microscopic structure of the hepatopancreas. Six isonitrogenous semipurified diets were fed to satiation to shrimp for 8 weeks in triplicate tanks (30 shrimps per tank) connected to a natural brackish water (6–8 g L−1) recirculating system. Diets contained different levels of cornstarch (100, 150, 200, 250, 300 and 350 g kg−1) as the source of carbohydrate and were balanced using cellulose. Weight gain (WG), survival rate and feed conversion rate (FCR) were considerably affected by cornstarch levels of diets. The highest WG (453.6 g kg−1) and best FCR was observed in shrimp fed the 150 g kg−1 (cornstarch level) diet and was significantly (P < 0.05) higher than those fed diets containing 250–350 g kg−1 cornstarch. However, the survival rate reached maximum in shrimp fed the 100 g kg−1 diet (96.7), some 30% higher than the lowest rate, which was found in shrimp fed the 250 g kg−1 diet. Body lipid tended to be higher in shrimp fed diets with higher cornstarch levels. The apparent digestibility of dry matter and crude fat increased with increasing levels of cornstarch and, hence, decreasing levels of cellulose. In addition, histological study on shrimp fed 10–350 g kg−1 diets exhibited histological changes. The overall conclusion was that the optimum cornstarch level may be set at 100–200 g kg−1 when the diets contain 380 g kg−1 protein.

“…Dietary types and levels of carbohydrate have been reported to cause alterations in hepatopancreas structure (Johnston et al, 2003;Piedad-Pascual et al, 1983;Simon and Jeffs, 2011). Piedad-Pascual et al (1983) suggested that the tubes of the hepatopancreas would be disrupted when shrimps were fed with diets containing 10% molasses and only the connective tissue capsule would be visible in some portions of the gland. On the contrary, Guo et al (2006) reported that the hepatopancreas exhibited no significant differences among groups fed with diets containing 100 to 350 g kg −1 cornstarch.…”

“…Histological analysis of the hepatopancreas has been used as a practical means for assessing the nutritional condition in the shrimp culture (Gimenez et al, 2004;Reddy et al, 1999).

“…It has been noted that this organ undergoes histological and histochemical modifications in response to physiological demands, such as molt (Al-Mohanna & Nott, 1989) and reproduction (Díaz et al, 2006), osmotic variations (Díaz et al, 2010) pollution (Popescu-Marinescu et al, 1997), and that there is a correlation between the midgut gland structure and the animal's physiological condition and nutrition (Piedad-Pascual et al, 1983;Fernández-Giménez et al, 2008;Fenucci et al, 2009).…”

ABSTRACT. The response of the midgut gland of Artemesia longinaris to salinity changes was evaluated by analyzing its histological changes. Animals were exposed gradually and abruptly to 33, 29, 25 and 16 psu for different time intervals and readapted to 33 psu for 30 days. Individuals maintained 10 days at 16 psu showed the lowest survival and presented histopathologies which were not present in those readapted to 33 psu. Shrimps abruptly transferred from 33 to 16 psu died in 3-5 h but did not show midgut gland alterations likely due to the brief exposure. Only shrimps abruptly transferred from 33 to 25 psu presented histopathologies after 96 h. When readapted to 33 psu for 30 days, the midgut gland recovered an unaltered structure. Except E-cells, which did not vary in height among treatments, F, R and B-cells were taller in animals gradually adapted to 29 than to 16 psu. Abrupt salinity changes had a significant effect on the mean height of F, R and B-cells of those animals transferred from 33 to 25 psu (from 24 to 96 h after transfer F and R-cells heights decreased, and from 96 to 144 h after transfer B-cells height increased). Our study shows the effect of osmotic stress at the tissue level on the midgut gland and, at least partially, explains the reason for the mortalities at low salinities. Keywords: midgut gland, hepatopancreas, osmotic stress, histopathology, salinity, A. longinaris, Argentina. Efecto de los cambios de salinidad sobre el hepatopáncreas deArtemesia longinaris (Decapoda, Penaeidae) RESUMEN. Se evaluó la respuesta del hepatopáncreas de Artemesia longinaris a los cambios de salinidad. Los animales fueron expuestos gradual y abruptamente a 33, 29, 25 y 16 psu durante distintos intervalos y readaptados a 33 psu por 30 días. Los individuos gradualmente adaptados a 16 psu tuvieron baja supervivencia y presentaron alteraciones histológicas ausentes en los readaptados a 33 psu. Aquellos transferidos repentinamente de 33 a 16 psu murieron en 3-5 h pero no mostraron alteraciones, posiblemente debido a la breve exposición. Sólo los transferidos repentinamente de 33 a 25 psu por más de 96 h presentaron daño tisular. Cuando se readaptaron a 33 psu durante 30 días, el hepatopáncreas mostró una estructura normal. Exceptuando las células E que no variaron en altura entre tratamientos, las F, R y B fueron más altas en los animales gradualmente adaptados de 33 a 29 psu. Los cambios súbitos de salinidad tuvieron un efecto significativo en la altura media de las células F, R y B solamente en animales transferidos de 33 a 25 psu (24 a 96 h después de la transferencia disminuyó la altura de las células F y R, y 96 a 144 h después hubo un aumento en la altura de las células B). El presente estudio muestra el efecto de los cambios de salinidad sobre el hepatopáncreas y explica, al menos parcialmente, la razón de la mortalidad a bajas salinidades.
