High density aquaculture of white shrimp (Litopenaeus vannamei) in controlled tank

Abstract

The study was aimed to evaluate the growth, survival rate and production of white shrimp (L. vannamei) culture under different stocking density in controlled tank. This research was conducted at Experimental Pond Installation. Research Institute for Coastal Aquaculture and Fisheries Extension in Maros Regency, South Sulawesi. Indonesia. Juveniles of white shrimp size in weight 0.14 g/ind were cultured for 70 days in three different stocking densities: 100, 200 and 300 ind/m3 in a total of nine fibre tanks sized of 2 m3. The study used Completely Randomized Design (CRD). with three replications for each treatment. The parameters observed were growth rate, survival rate, production, feed conversion ratio of white shrimp and water quality condition. The results showed that the different stocking density had a significant effect (P <0.05) on growth, survival rate and production of white shrimp. The final weight and absolute weight of vaname shrimp decreased as density increased to 300 ind/ m3. The final weight of vaname shrimp in treatments A. B and C were 13.70 g/ind, 12.27 g/ind and 10.90 g/ind respectively. Survival rate and production of white shrimp in this study ranged from 80-95% and 1.24-2.42 kg/m3 respectively. Water quality measured during the experiment was suitable for the growth of white shrimp.

Growth and population modelling based on density of the Pacific white shrimp intensively cultured in freshwater

“…Nonetheless, our data of simulated individual numbers demonstrate the relevance of time in high densities conditions and how population is reduced. This observation confirms that increased shrimp densities in an intense aquaculture system lead to a reduction in biomass due to low survival and growth associated to the overcrowding stress (Suwoyo & Hendrajat, 2021;Yu et al, 2009) (Figure 2).…”

Arambul‐Muñoz et al (2019) suggest a production with lower density can be more profitable, given that production time would increase in higher population densities, along with operational costs; yet economic analysis was not included in our analysis.…”

“…Therefore, farmers seeking to improve management strategies can benefit from using the Potential model applied to stocking density, as our results indicate that its use can provide profitably production and reduce operational costs (Daudpota et al, 2014;Heaps, 1995;Suwoyo & Hendrajat, 2021).…”

“…Survival and growth depend on density; its pattern is usually representative in intense shrimp cultures due to the combination of factors particularly feed and space competition, increased cannibalism, decreased water quality and accumulated organic waste (Arnold et al, 2006; Pérez‐Castañeda & Defeo, 2005; Suwoyo & Hendrajat, 2021; Yu et al, 2009). From the validation analysis, G 3 was the function that best represented the decrease in population dynamics.…”

A recombinase polymerase amplification and Pyrococcus furiosus Argonaute combined method for ultra‐sensitive detection of white spot syndrome virus in shrimp

“…Penaeus vannamei is an important economic shrimp species and one of the three most productive farmed shrimp species (Albalat et al, 2022; Figueredo et al, 2022; Lightner, 2011). Nowadays, with the growing of highly integrated high‐density shrimp farming, outbreaks of infectious aquatic diseases become much more frequent, seriously threatening the security of shrimp farming globally (Bardera et al, 2021; Escobedo‐Bonilla et al, 2008; Petesch et al, 2021; Suwoyo & Hendrajat, 2021). White spot disease (WSD) in shrimp is a serious infectious disease caused by white spot syndrome virus (WSSV).…”
