Maturity, spawning and feeding intensity of cobia Rachycentron canadum (Linnaeus, 1766) in northwest coast of India
An attempt was made to provide some vital aspects of reproductive biology of cobia Rachycentron canadum (Linnaeus, 1766). Samples for a period of two years from an exploratory vessel and from the landing centers of Mumbai were used for the study. The average sex ratio between males and females observed was 1:0.80. Dominance of the number of females above the size of 100 cm was noticed. The size...
متن کاملResponse to ocean acidification in larvae of a large tropical marine fish, Rachycentron canadum.
Currently, ocean acidification is occurring at a faster rate than at any time in the last 300 million years, posing an ecological challenge to marine organisms globally. There is a critical need to understand the effects of acidification on the vulnerable larval stages of marine fishes, as there is potential for large ecological and economic impacts on fish populations and the human economies t...
متن کاملA Case Study on the Mortality of Cobia (Rachycentron canadum) Cultured in Traditional Cages.
The mass mortality of cobia (Rachycentron canadum) within 2-3 days was reported by 3 private farms in Bukit Tambun, Pulau Pinang, in February and March 2007. Only cobia with body weights of 3-4 kg were affected. Most diseased cobia swam on the surface and displayed flashing behaviour. All samples were positive for viral nervous necrosis (VNN) with low to medium levels of infection. Infestations...
متن کاملCardio-respiratory function during exercise in the cobia, Rachycentron canadum: The impact of crude oil exposure.
Aerobic exercise capacity is dependent on the cardiorespiratory system's ability to supply oxygen at a rate that meets energetic demands. In teleost fish crude oil exposure, with the associated polycyclic aromatic hydrocarbons (PAH's), reduces exercise performance and this has been hypothesized to be due to compromised cardiovascular function. In this study, we test this hypothesis by simultane...
متن کاملThe Effect of TLR9 Agonist CpG Oligodeoxynucleotides on the Intestinal Immune Response of Cobia (Rachycentron canadum)
Cytosine-guanine oligodeoxynucleotide (CpG ODN) motifs of bacterial DNA are recognized through toll-like receptor 9 (TLR9) and are potent activators of innate immunity. However, the interaction between TLR9 and CpG ODN in aquatic species has not been well characterized. Hence, cobia TLR9 isoform B (RCTLR9B) was cloned and its expression and induction in intestine were investigated. RCTLR9B cDNA...
