Physiological response and growth performance of spiny lobster (Panulirus homarus) juvenile rearing in recirculating aquaculture system with various shelter type

Abstract

Spiny lobster nursery is done to produce more adaptive and uniform juvenile lobsters quality. Shelters used in spiny lobster nursery served to reduce physical contact among lobsters in the rearing tank. The purpose of this study was to analyze the effect of different shelter types on physiological response and growth of spiny lobster (Panulirus homarus) juvenile rearing in recirculating aquaculture systems. Lobsters with an average weight of 50.07 ± 2.89 g were reared for 60 days. They were fed once a day with trash fish. The daily feeding rate was 3-4% of total weight. This study used four types of shelter as treatments with two replications. PVC pipe shelter as control (K), individual shelter square shaped (IS ■), individual shelter triangle shaped (IS ▲), and individual shelter tube shaped (IS ●). The weight and length of the lobster carapace improved with the duration of the research in all treatments. Throughout the trial, glucose levels in controls were generally greater than those in specific shelf treatments. The reaction of lobster hemolymph total protein to different shelters is highly variable. Overall, the usage of individual shelters had a considerable positive influence on grown lobsters in this study. This is because individual shelter eliminates contact between lobsters, eliminating the possibility of cannibalism in the cultivation container. This study concludes that IS ■ used in rearing Panulirus homarus showed a lower stress response than the other treatments in terms of glucose and total protein lobster hemolymph during the study. IS ■ is the best because it reduced stress levels and yielded better total biomass among the other treatments.

Barriers in European spiny lobster (Palinurus elephas) aquaculture: What we know so far?

“…It may be of benefit to incorporate natural substrate to mimic a wild environment. For P. homarus juveniles, there was a preference for triangular‐shaped shelter over PVC piping, square and tube‐shaped shelters 136 . Other studies have shown that shelters suspended in the water column at open‐water sea sites significantly increased survival rates in spiny lobsters 17,137,138 .…”

Availability of puerulus from natural catch for lobster panulirus spp. nursery culture

“…Mortality risk during transportation can be reduced using a wet packing with oxygen in addition to preserving the physiological and metabolism activities that remain in optimum condition for puerulus (Arumugam et al 2020). The habitat difference in the rearing tank and transportation box due to shelter absence can trigger puerulus stress (Supriyono et al, 2017;Adiyana et al, 2020;Slamet et al, 2021). Administration of an anesthetic substance can also be used to reduce the stress level in transporting the living lobsters (Pozhoth and Jeffs, 2022).…”

Health Status of Spiny Lobster Panulirus homarus with Sub-Mersible Net Cage System in the Different Depths at Kepulauan Seribu, DKI Jakarta

“…Lobster culture was firstly conducted in a floating-net cage that produced financial profit to the culturists (Solanki et al, 2012;Daniels et al, 2015;Rao et al, 2020, Dinesh et al, 2022. This commodity has also been maintained indoor in the land, namely in the plastic tank with recirculation system (Adiyana et al, 2020). The lobster culture effort in a sub-mersive cage is being applied currently to provide more appropriate environment for this species physiologically (Fitzgibbon et al, 2017).…”

“…Vietnam is the world's main cultured lobster, although has currently been suffering from high mortality level, disease outbreak, and Chinese market dependence . Several studies have been performed to increase the lobster culture productivity, such as artificial feed improvement (Slamet et al, 2020), culture system (Mustafa, 2013), and maintenance technology (Adiyana et al, 2014;Adiyana et al, 2015;Adiyana et al, 2020).…”
