Abstract:

Background: Shrimp farming is evolving from semi-intensive to hyper-intensive systems with biofloc technology and water recirculation systems. Objective: To evaluate the transcriptional response promoted by biofloc on shrimp (Litopenaeus vannamei) under a recirculating aquaculture system (RAS). Methods: Quantitative real-time RT-PCR was used to monitor seven key genes related to the immune system in shrimp post-larvae, reared in a RAS with and without biofloc (BF and noBF). In addition, we present for the first time nucleotide sequences of ADP-ribosylation factor 4 (LvArf4) from Litopenaeus va

AbstrakPengembangan kewirausahaan pesantren menjadi sesuatu yang perlu untuk dikembangkan dengan tujuan untuk menumbuhkan semangat kemandirian pada para pengelola pondok pesantren. Hanya saja, sejauh ini masih banyak faktor kendala mengenai minimnya pengetahuan dan wawasan dari pihak pengelola pesantren mengenai pengelolaan wirausaha yang tepat, khususnya dalam hal pembudidayaan lele. Budidaya lele ini dipilih, mengingat peluang pasarnya sebenarnya cukup besar, dan pembudidayaannya cenderung relatif mudah dan praktis. Hanya saja sangat disayangkan, pola pembudidayaan lele yang pernah dicoba se

Ammonia is the main pollution factor of the aquatic environment in marine shrimp culture systems. In order to demonstrate the feasibility of the combination of biofloc technology and nitrifying biofilter for the ammonia removal, a 70-day production trial was conducted in a simplified pilot-scale hybrid biofloc-based recirculating aquaculture system (biofloc-RAS) with the intensive culture of Litopenaeus vannamei. Nitrogen dynamics and nitrifying microbial communities were investigated in three replicated systems simultaneously under the conditions of high feed loading and zero water exchange.
