“…Esto le proporciona plasticidad morfológica y cromática apropiada para permanecer con éxito en cada uno de estos ambientes (Guzmán-Arroyo, 1987). Asimismo, se he demostrado que para los estadios larvarios del género Macrobrachium la intensidad y calidad de la luz es de vital importancia para un crecimiento adecuado (Araujo & Valenti, 2011;Maciel & Valenti, 2012). La intensidad de luz puede también inducir un cambio de coloración como consecuencia de la activación de pigmentos que se encuentran en células especializadas llamadas cromatóforos, base de cualquier arreglo cromático (Noél & Chassard-Bouchaud, 2004;Boyle & McNamara, 2005).…”

“…En estos estadios intermedios se alimentan de presas que responden a la luz, como nauplios de Artemia (Maciel & Valenti, 2012). Al respecto, Araujo & Valenti (2011), mencionan que la intensidad de 390 lux acelera el desarrollo de las larvas de M. amazonicum, aumenta la productividad y ganancia en peso en comparación a intensidades menores, pero no mencionan nada en relación al efecto de la luz en la intensidad de color de las larvas.…”

Sin embargo, Maciel & Valenti (2012) señalan que una alta intensidad de luz puede ser un factor de estrés que puede contribuir a reducir la supervivencia, ya que durante su desarrollo las larvas agudizan su visión en relación con diferentes longitudes de onda de luz y el aumento del brillo. El contraste y reflectancia de luz, afecta la discriminación visual, el comportamiento de caza y el estrés.…”

RESUMEN.Macrobrachium tenellum es un langostino dulceacuícola que destaca por su capacidad de cambio en función de diferentes estímulos. Para determinar el efecto de diferentes intensidades de luz sobre la expresión de cromatóforos, crecimiento y supervivencia, se sometieron langostinos juveniles (28.60-28.97 mm) a cuatro tratamientos 30, 600, 1500 y 3500 lux, durante 45 días. Al final de experimento se determinó el crecimiento en talla y peso, cantidad de alimento consumido, factor de conversión alimenticia y supervivencia. El análisis de la expresión de cromatóforos se efectuó mediante su conteo a partir de fotos del tercer somita y exopoditos de los urópodos. El crecimiento en peso y talla de los organismos sometidos a las diferentes intensidades de luz no mostró diferencias significativas entre tratamientos (P > 0,05). El consumo total de alimento, factor de conversión alimenticia y supervivencia tampoco resultaron con diferencias significativas. Respecto de la cantidad de cromatóforos hubo diferencias entre tratamientos, las dos intensidades menores de luz y las dos mayores intensidades de luz fueron diferentes, a mayor intensidad de luz mayor número de cromatóforos expresados.

Effect of different light intensities on expression of chromatophores, growth and survival in juvenile Macrobrachium tenellumABSTRACT. Freshwater prawn Macrobrachium tenellum is noted for its ability to change color depending on different stimuli. In order to determine different light intensities on the chromatophore expression, growth and survival, juvenile shrimps (28.60-28.97 mm) were subjected to four treatments 30, 600, 1500 and 3500 lux for 45 days. At the end of the experiment the growth in size and weight, amount of food consumed, feed conversion and survival were determined. The expression analysis of chromatophores was performed by its count from photos of the third somite and the uropod exopodite. Growth in height and weight of prawns subject to the different light intensities showed no differences between treatments (P > 0.05). The total consumption of food, feed conversion and survival showed no significant differences. In relation with the number of chromatophores, differences between treatments were evident; lower light intensities were different to higher ones. The higher light intensity increased the number of expressing chromatophores. Keyword: Macrobrachium tenellum, river prawn, pigmentation, light effect, aquaculture.La concentración y distribución de pigmentos que otorga la coloración en los crustáceos está determinada por muchos factores tanto intrínsecos (especie, sexo y talla), como extrínsecos (color del fondo del ambiente, temperatura, alimentación y luz) (Hung-Pan et al., 2001). ___________________ Corresponding editor: Erich RudolphEntre los factores extrínsecos, la luz es uno de los más determinantes pues además incide en su crecimiento y conducta debido a que tanto su metabolismo, hábitos diarios, ciclos...

-Effects of four feeding regimes on the development and feed intake, survival, productivity, and growth of Macrobrachium amazonicum larvae were investigated. Larvae were fed from stage II to IX, as follows: Artemia nauplii + inert diet during the entire larval cycle (AIn); Artemia nauplii for the entire larval cycle + inert diet from stage V onward (A/AIn); Artemia nauplii until stage IV + inert diet from stage IV onward (A/In); and only inert diet for the entire larval cycle (In). Each feeding regime (treatment) was carried out in three 50-L rectangular black tanks, set up in a recirculating system, filled with 10 salinity brackish water, and stocked at 81.8±0.8 larvae/L. The larval stage index, occurrence of Artemia nauplii and/or inert feed into the digestive tract, survival (number of larvae and postlarvae), productivity (number of postlarvae/L), and weight gain (mg) were evaluated. Larval development was similar in treatments AIn, A/Ain, and A/In, but was delayed in treatment In. Artemia nauplii were ingested by larvae irrespective of developmental stages, while inert feed was ingested only from stage III onward. Survival and productivity were higher in treatment AIn and decreased according to the number of days larvae were fed Artemia nauplii. Macrobrachium amazonicum larvae are omnivorous and polytrophic, but live feed is essential in the first stages and act as a complementary diet in the last half of larval cycle. There is a potential for inert diet to replace Artemia in the last phase of development if the nutrient composition matches larvae requirements. The combination of Artemia nauplii and inert diet during all larval cycles is the best management to maximize productivity.

Recebido em 30/06/2016Resumo -Macrobrachium acanthurus é um camarão de água doce nativo do Brasil que apresenta grande potencial de cultivo. No entanto, ainda não se dispõe de um protocolo para larvicultura desta espécie. Neste trabalho, investigou-se a oferta da dieta inerte para a espécie em questão. Larvas de M. acanthurus foram obtidas a partir de fêmeas ovígeras coletadas no Delta do Rio Parnaíba-PI. A larvicultura de M. acanthurus foi realizada em sistema aberto em baldes com densidade de estocagem de 50 larvas/L e salinidade 16. As larvas foram monitoradas diariamente para identificação dos estágios e avaliação das condições gerais de saúde. O desenvolvimento completo foi obtido a partir do 35º dia de cultivo e para descrição dos estágios larvais os exemplares foram fixados em glicerina. As larvas de M. acanthurus foram alimentadas com náuplios recém-eclodidos de Artemia, até alcançarem o estágio VI. A partir de então foi introduzida a dieta inerte seguindo protocolos já descritos na literatura para outras espécies como Macrobrachium amazonicum e Macrobrachium rosenbergii. O delineamento foi inteiramente casualizado com três tratamentos e quatro repetições. Resultados apontam para uma possível viabilidade da utilização da dieta úmida em sistemas com menor nível de manejo.Palavras-Chave: Alimentação, Dieta inerte, Estágio larval, Manejo, Stress DIET ON THE HATCHERY OF MACROBRACHIUM ACANTHURUS (WIEGMANN,1836) IN OPEN SYSTEMAbstract -Macrobrachium acanthurus is a native freshwater prawn from Brazil that has great potential for cultivation. However, does not have a protocol for hatchery this specie. In this study, we investigated the supply of inert diet for the species in question. The larvae of M. acanthurus were obtained from ovigerous females collected in Delta do Rio Parnaiba -PI. M. acanthurus hatchery operating in open system in buckets at 50 larvae/L stocking density and salinity 16. The larvae were monitored daily for identification of the stages and evaluation of the general health conditions. Complete development was obtained by the 35 th day of cultivation and for the description of the larval stages the samples were fixed in glycerine. M. acanthurus larvae were fed with newly hatched Artemia nauplii until they reached the stage VI. Since then was introduced to inert diet following protocols described in the literature for other species like Macrobrachium amazonicum and Macrobrachium rosenbergii. The experiment were set up as a completely randomized design with three treatments and four replications. Results point to a possible feasibility of using the wet diet in systems with low management level.
