Trachinotus blochii is a promising mariculture fish species. Scientific data on biosafety and fillet residues of florfenicol exposure, one recommended amphenicol antimicrobial for aquaculture use, remains unknown in T. blochii, despite its criticality for prudent application. Accordingly, the paper evaluated the safety (regarding mortality, symptoms, weight gain, and histopathology) of dietary florfenicol after therapeutic (10 mg Kg-1 for ten days) and excessive (three, five, and ten times the therapeutic dose for 10, 20, and 30 days) exposures. There was no mortality in any group. The clinical abnormalities were noted only in 10X group from the 25th exposure day, which disappeared on the fourth day after withdrawal. Reduced growth was recorded at 5X and 10X groups from 20 and 30 exposure days, respectively. Histological lesion`s severity was in the liver > kidney > gill > spleen > muscle > intestine. The lesion severity relied on the quantity and duration of exposures, with maximum severity in 5X and 10X groups on the 30th day. After recommended therapeutic exposure, fillet residues were below the maximum residual limit accepted by the European Union (1000 μg Kg-1) from day three of the withdrawal, showing a minimum three-day is necessary to reach a safe, acceptable level.

It is of note that the capture fisheries are under stress for many targeted species. To reduce the pressure on the wild, research on mariculture had been practicing for decades. Even though technologies for captive breeding are standardized, the growth and survival of the larvae of candidate marine fish species are still not up to the mark. It is necessary to focus and encourage new approaches to standardize the hatchery protocol for enhanced production and sustainable management towards future demands. The major concern facing the marine fish hatchery is the delivery of nutritionally enriched feeds to the larvae. Inadequate nutrition is one of the major reasons for early mortality, weaning mortality, cannibalism, inadequate growth, lowered immunity etc. In India, nutrigenomics research is an up-and-coming field, especially the transcriptomics approach that can be applied to understand the gene expression profile of the larvae and juveniles with respect to nutritional interventions. By means of RNA sequencing (RNA-seq) technology, a clear understanding of the growth, development, metabolism, immune function, stress, adaptation and differential gene expression is possible. In addition, the specific effects of selected nutrients on targeted genes can be studied to alter the diet composition accordingly for improving the growth, condition and survival of candidate species of marine fish larvae. This novel approach has the potential to unravel valuable information required to address the issues in marine fish larval nutrition and for the development of species and life-stage specific micro-feeds for sustainable larviculture., {"references":["Callet, T., Dupont-nivet, M., Cluzeaud, M., Jaffrezic, F., Quillet, E., Geurden, I., Kerneis, T., Labbe, L., Mazurais, D., and Skiba-cassy, S., 2022.

All the bank marketing campaigns mostly deals with large amount of data. when they need to deal with huge electronic data of customers, then it is very difficult to analyze the data manually or by human analyst. Here comes the picture of data mining techniques to deal with the large amount of data and to come up with useful data which helps in decision making process. All the data mining techniques helps in analyzing the data. some of the techniques that can be used for this bank marketing campaigns are naive bayes, logistics regression technique and Decision tree model technique etc. among all these techniques decision Tree model gives the best solution in analyzing the human decisions. Artificial neural networks is a learning algorithm which learns from multiple individual decisions and their judgements, thus aggregates and generalizes the customers decision making knowledge.
