As part of preliminary work aimed at the development of a formulated diet for the mud crab, Scylla serrata, an experiment was conducted with juvenile mud crabs (95.65±2.17 g) to determine apparent digestibility coefficients (ADC) for cellulose, fish meal, shrimp meal, blood meal, soybean meal, wheat flour and cod liver oil. Apparent digestibility coefficients for dry matter (ADCdm), energy (ADCenergy) and protein (ADC protein) were in the ranges 70.0-95.7%, 77.4-97.1% and 57.7-97.9% respectively. Soybean meal had the highest ADCdm and wheat flour had the lowest value (P<0.05), while the ADCdm for fish meal, blood meal and shrimp meal were not different (P?0.05). Similarly, soybean meal had the same ADCenergy as that of fish meal, but higher than those of cod liver oil, blood meal and shrimp meal (P<0.05). Moreover, the ADC protein for blood meal or shrimp meal were not significantly different from fish meal (P?0.05); nevertheless, they were lower than that of soybean meal and higher than that of wheat flour (P<0.05). Of significant interest was the ADCdm (78.0%) and ADCenergy (77.4%) for cellulose, which indicates that plant-based nutrient sources may well be a useful component of formulated diets for mud crabs.

Intensive nursery systems are designed to culture mud crab postlarvae through a critical phase in preparation for stocking into growout systems. This study investigated the influence of stocking density and provision of artificial habitat on the yield of a cage culture system. For each of three batches of postlarvae, survival, growth and claw loss were assessed after each of three nursery phases ending at crab instars C1/C2, C4/C5 and C7/C8. Survival through the first phase was highly variable among batches with a maximum survival of 80% from megalops to a mean crab instar of 1.5. Stocking density between 625 and 2300 m-2 did not influence survival or growth in this first phase. Stocking densities tested in phases 2 and 3 were 62.5, 125 and 250 m -2. At the end of phases 2 and 3, there were five instar stages present, representing a more than 20-fold size disparity within the populations. Survival became increasingly density-sensitive following the first phase, with higher densities resulting in significantly lower survival (phase 2: 63% vs. 79%; phase 3: 57% vs. 64%). The addition of artificial habitat in the form of pleated netting significantly improved survival at all densities. The mean instar attained by the end of phase 2 was significantly larger at a lower stocking density and without artificial habitat. No significant effect of density or habitat on harvest size was detected in phase 3. The highest incidence of claw loss was 36% but was reduced by lowering stocking densities and addition of habitat. For intensive commercial production, yield can be significantly increased by addition of a simple net structure but rapidly decreases the longer crablets remain in the nursery.

[ES] Terencio fue uno de los autores que mayor interés suscitaron en Petrarca desde un punto de vista filológico, y sabemos que glosó al menos alguno de los varios mss. terencianos que estaban en su biblioteca. No conservamos ningún Terencio anotado de su puño y letra, pero tenemos dos mss. que (gracias a las subscriptiones que contienen) sabemos descienden de un ejemplar petrarquesco: sin embargo, y debido sobre todo a la extraordinaria complejidad de la historia del texto terenciano, la relación entre ambos mss. no había podido aclararse ni, por tanto, se había progresado en la reconstrucción del Terencio de Petrarca. Las principales aportaciones del presente artículo podrían resumirse así: 1, se identifican nuevos mss. que descienden del Terencio de Petrarca y se demuestra (en contra de lo que habían sostenido expresamente Sabbadini y Billanovich) que la importante edición terenciana de Pietro da Moglio (muy difundida sobre todo en Italia) contiene el mismo texto que los mss. de Petrarca; 2, se sitúa el conjunto que conforman todos estos mss. en la tradición de Terencio, y esto permite mostrar que la labor filológica realizada por Petrarca sobre el texto de las comedias no consistió en intentar restablecer la colometría correcta (como venía defendiéndose hasta ahora a partir de las subscriptiones antes citadas), sino en saber apreciar un Terencio particularmente noble y, a través del cotejo con otros mss., proponer puntualmente una colometría alternativa (pues, en efecto, se han descubierto marcas métricas que parece deben asignarse a Petrarca); 3, gracias en buena parte a los mss. nuevamente identificados (muy en particular al ms. de Estocolmo), se han podido atribuir a Petrarca glosas que se encuentran en algunos de ellos, aunque distinguiendo entre apostillas del propio Petrarca y glosas que con seguridad se encontraban en su ejemplar pero que provienen de otros mss.
