“…It was noticed that there was no significant variation in costs of the shrimp farm which can be observed from the standard deviation of all the costs. Studies reported that the feed cost contributes more than two‐third of the total cost in shrimp production (Engle et al, 2017; Sivaraman et al, 2019) which is also found in the present study. An ideal feeding pattern is imperative for better growth and survival that remarkably influences the economic profit of shrimp culture (Nisar et al, 2021).…”

“…Other than seed quality, disease‐free environmental management program improve the survival rate (Liao & Liao, 2006). Implementation of better management practices also could enhance the production of shrimp for a prolonged period with higher survival (Sivaraman et al, 2019). The feed conversion ratio was also significant in explaining shrimp production.…”

“…The cost and return of the commercially farmed shrimp in Tamil Nadu were estimated by enterprise budget which is a simple and readily understandable measure of profitability (Engle, 2010). The enterprise budget has been employed in various fields of fisheries and aquaculture including shrimp farming (Sivaraman et al, 2019)). The net profit was calculated by subtracting the total cost from the gross revenue.…”

Shrimp aquaculture has gained significant attention to meet the animal protein need of the growing world population and is widely cultured in semi-intensive methods around the world including India. Here, we examined the growth performance and enterprise budget of shrimp farming using field-level survey data from 194 farms in Tamil Nadu for successive two crops of a year. An estimated shrimp production was 5880 kg/ha/crop from an average pond size of 2.93 ha and stocking density of 39 numbers m −2 for a culture period of 92 days. Similarly, in terms of feed, a total of 9117 kg/ha/crop was found to be used with an average food conversion ratio of 1.55 kg. An initial capital investment requirement of USD $ 22062.11 was observed.The fixed cost of USD $ 2984.21 and variable cost of USD $ 40685.13 were recorded in the production process of shrimp. The harvested shrimp quantity (5880 kg/ha/crop) generated gross revenue of USD $ 50405.56 ha/yr. The calculated net revenue for the shrimp farms of Tamil Nadu was USD $ 6736.22. The Cobb-Douglas production function results showed that water salinity, culture days, stocking density, quantity of feed used, shrimp harvest size, harvest count, daily weight gain, specific growth rate and survival rate was positively influencing the economic performance of the shrimp but not statistically significant. Whereas, the food conversion ratio statistically negatively influenced the economic performance of shrimp production in Tamil Nadu.

“…Eke, around 50% of respondents operated the farm at highest technical efficiency of >0.95. The overall performance and highest technical efficiency were achieved in the Nellore region due to similar kind of farm management practices such as pond preparation, seed quality and stocking practices, feed management, water quality management, health management, and harvest and post‐harvest management (Sivaraman et al., 2019).…”

Chitosan is a cationic polymer obtained by deacetylation of chitin, found abundantly in crustacean, insect, arthropod exoskeletons, and molluscs. The process of obtaining chitin by the chemical extraction method comprises the steps of deproteinization, demineralization, and discoloration. To obtain chitosan, the deacetylation of chitin is necessary. These polymers can also be extracted through the biological extraction method involving the use of microorganisms. Chitosan has biodegradable and biocompatible properties, being applied in the pharmaceutical, cosmetic, food, biomedical, chemical, and textile industries. Chitosan and its derivatives may be used in the form of gels, beads, membranes, films, and sponges, depending on their application. Polymer blending can also be performed to improve the mechanical properties of the bioproduct. This review aims to provide the latest information on existing methods for chitin and chitosan recovery from marine waste as well as their applications.
