Abstract: The potential benefits of ripe cultivated banana CV. Kluai Namwa (Musa sapientum Linn.) as a natural feed supplementation in practical diet on growth performance, feed utilization, innate immunity and disease resistance against Streptococcus agalactiae infection in hybrid tilapia (Oreochromis niloticus x O. mossambicus) were evaluated. Fish were fed with the test diet containing different levels of ripe cultivated banana (RCB) supplements (10, 30 and 50 g/kg diet) compared with the negative control and positive control diet for 60 days. Results showed that growth parameters, feed efficiency and lysozyme activity values in the positive control group (vitamins and minerals premix added) were significantly higher than the negative control group (without any premix supplements) but differences among the RCB supplementary diet group and the positive control group were not statistically significant. After challenged with Streptococcus agalactiae, the cumulative mortality of fish in the positive control group was lowest (0%), the percent survivals were 62.22%, 66.67%, 83.33% and 88.89% in the negative control, 10RCB, 30RCB, and 50RCB treatments, respectively. These results showed that the RCB supplementary diets had unaffected on growth performances and could be potential as an immunostimulant to improve fish health for red tilapia aquaculture.

Abstract: The black tiger shrimp (Penaeus monodon) is an aquatic animal with considerable economic importance. Poor reproductive maturation in captivity impedes sustainable aquaculture production of this species. This study aims to provide transcriptomic information on reproductive organs using 454 pyrosequencing technology. The transcriptome analysis of ovaries and testes revealed 41,136 transcripts with 20,192 contigs. We found novel sets of transcripts completing several important reproductive pathways such as gonadotropin-releasing hormone (GnRH) signaling and progesterone-mediated oocyte maturation. In addition, we found transcripts encoding for receptors crucial for initiation of the maturation process, such as GnRH receptor (GnRHR), voltage-dependent calcium channel L type alpha-1C (CACNA1C) and epidermal growth factor receptor (EGFR). Moreover, we found a putative novel vigillin encoding for an estrogen-induced polysome-associated protein, which has not been reported in penaeid shrimp. These results suggest that the regulatory mechanism of the pathways important to reproductive maturation might be similar to those in the vertebrate. The obtained data will consequently accelerate the study of reproductive biology of this important species to ensure a sustainable shrimp farming industry.
