“…Higher survival rates and greater progress in the larval development of shrimp are directly related to appropriate maintenance conditions (7,13); nevertheless, some researchers who studied the combined effect of salinity and temperature in L. vannamei concluded that biomass respiration, excretion and growth were the best survival indicators (19)(20)(21). As in this study, other authors have reported that salinity and temperature have an influence on the larval development index of Penaeus merguiensis and on the survival of Litopenaeus stylirostris (5,22).…”

“…Nevertheless, it is known that L. vannamei larval stages (nauplius, zoea, mysis) and PL1 can tolerate salinities between 20 and 45ups (6), due to the fact that it is a euryhaline species under natural conditions (24). Nevertheless, there is evidence to show that penaeidae larvae are less resistant to abrupt salinity and temperature variations (22), mainly due to the fact that its gills and other structures specialized in osmoregulation have not developed completely.…”

Objetive. The combined effect of salinity (25, 30, 35, and 40psu) and temperature (25, 30, and 35 o C) was evaluated on survival and development from nauplii V (NV) larvae until postlarvae (PL1) of Litopenaeus vannamei. Materials and methods. Four replicates were applied to each combination of salinity and temperature. The larvae were placed in 12 L beakers a density of 100larvae/L. Salinity was increased dissolving commercial salt without iodine, into marine water, whereas fresh filtered tap water was used to decrease the salinity from seawater. The NV were adapted at 35psu and 30°C during 30 minutes. Thereafter, were transferred at each experimental combination of salinity and temperature. Every 24 h, samples of larvae were obtained to determine in vivo their stage of development and survival. All data were analyzed using a two-way ANOVA. Results. Survival and larval development were significantly (p<0.05) affected by salinity, temperature and interaction of both factors. Maximum ultimate survival to PL1 was obtained at 30°C and 30psu (82.2%) followed by 30 and 35°C at 25psu (71.5 y 71.6%). The highest development at PL1 was found at 30°C and 30psu (6.76). Larval development during experiment was lower at 25°C as compared to 30 and 35°C, regardless of the salinity levels. Conclusions. The most adequate conditions for survival and larval development were obtained between 30-35°C and 25-30psu.Keywords: Aquatic environment, crustacea, larvae, saline waters (Source: DeCS).

Materiales y métodos. Los experimentos se realizaron por cuadriplicado por cada combinación de salinidad y temperatura. Las larvas se mantuvieron en acuarios de 12 L a una densidad de 100larvas/L. La salinidad se incrementó disolviendo sal granulada libre de yodo, a partir de agua de mar, mientras que para alcanzar las salinidades menores se utilizó agua dulce filtrada. Los NV aclimatados a 35ups y 30°C durante 30 minutos fueron transferidos a cada combinación experimental de salinidad y temperatura. Cada 24 h, se obtuvieron muestras de larvas para determinar in vivo su etapa de desarrollo y supervivencia. Los datos fueron analizados por un ANOVA de dos vías. Resultados.

Juveniles of wild Pacific blue shrimp Litopenaeus stylirostris (mean initial weight ± standard deviation = 1.5 ± 0.1 g) were acclimated from a natural seawater salinity of 35‰ to salinities of 0, 2.5, 5.0, 7.5, 10, 15, and 25‰. After reaching the desired salinities, L. stylirostris were cultured for 32 d and growth, feed conversion ratio, and survival, as well as hemolymph and culture water osmolality, were determined. The L. stylirostris exposed to 0‰ died before or shortly after reaching the salinity end point. Final mean body weight of L. stylirostris held at 2.5‰ (3.1 ± 0.8 g) was significantly reduced compared with all other treatments. In contrast, those held at salinities from 5‰ to 35‰ had similar performance, with mean body final weight ranging from 3.8 to 4.5 g, showing that L. stylirostris can be cultured across this range of salinities without adversely affecting growth, survival, or feed conversion ratio. Litopenaeus stylirostris is a euryhaline organism, able to maintain its hemolymph osmolality relatively constant despite changes in salinity. The isosmotic salinity of L. stylirostris, estimated from the point of intersection between the regression lines of water salinity versus water osmolality and water salinity versus hemolymph osmolality, was 26.7‰. Litopenaeus stylirostris is an efficient osmoregulator with potential for low-salinity culture.

Branchial chambers constitute the main osmoregulatory site in almost all decapod crustaceans. However, few studies have been devoted to elucidate the cellular function of specific cells in every osmoregulatory structure of the branchial chambers. In decapod crustaceans, it is well-known that the osmoregulatory function is localized in specific structures that progressively specialize from early developmental stages while specific molecular mechanisms occur. In this study, we found that although the structures developed progressively during the larval and postlarval stages, before reaching juvenile or adult morphology, the osmoregulatory capabilities of Litopenaeus vannamei were gradually established only during the development of branchiostegites and epipodites, but not gills. The cellular structures of the branchial chambers observed during the larval phase do not present the typical ultrastructure of ionocytes, neither N a + /K + -ATPase expression, likely indicating that pleura, branchiostegites, or bud gills do not participate in osmoregulation. During early postlarval stages, the lack of N a + / K + -ATPase immunoreactivity of the ionocytes from the branchiostegites and epipodites suggests that they are immature ionocytes (ionocytes type I). It could be inferred from IIF and TEM results that epipodites and branchiostegites are involved in iono-osmoregulation from PL15, while gills and pleura do not participate in this function.
