Genome assembly at chromosome scale with telomere ends for Pearlspot, Etroplus suratensis.

The pearlspot, Etroplus suratensis is a climate resilient cichlid fish that exhibits unusual adaptation to salinity. The fish is able to complete full life cycle in diverse salinity habitats ranging from fresh water to marine environments. High-quality primary and phased genome assemblies were generated for pearlspot fish using PacBio HiFi and Arima HiC sequencing technologies, for the first time.

Bio-augmentation of heterotrophic bacteria in biofloc system improves growth, survival, and immunity of Indian white shrimp Penaeus indicus.

Effect of bio-augmentation of Bacillus spp in biofloc on growth, survival and immunity in Indian white shrimp Penaeus indicus was evaluated. Nine Bacillus strains were isolated and screened individually as well as in the form of a consortia. To maintain a C:N ratio of 12:1 a blend of carbohydrate sources was used.

First record of Cymothoa indica (Crustacea, Isopoda, Cymothoidae) infecting the cultured catfish Mystus gulio in India.

Cymothoa indica (Isopoda, Cymothoidae) is reported parasitizing the long-whiskered catfish Mystus gulio, cultured in an experimental cage in India. The specimens observed were adult males and females, which had mainly settled in the buccal cavity of juvenile catfish. The species was previously known from wild populations of Siganidae and Belonidae, but this is the first record of C.
