“…Irrespective of diets, the survival of juveniles remained constant and was similar to that reported by Smith et.al ( 2003), but higher than the previously reported by (Haryanti et al, 2017;Smith et.al 2005). The individual rearing system used in the present study has successfully protected the lobster juvenile from cannibalism and also assisted in assessing moult rates and moult intervals of the individual lobsters.…”

An evaluation of six dietary protein to energy (P/E) ratios was conducted in the early juveniles of ornate spiny lobster (Panulirus ornatus) by investigating the effects on physiology, digestive enzyme activities, body composition and amino acid profiles. Lobster juveniles (0.25 ± 0.01 g) were individually kept in aquaria and fed 6 isoenergetic formulated diets consisting of three protein levels (450, 500 and 550 g kg− 1) and three lipid levels (7, 9 and 13 g kg− 1) having P/E ratios of 21, 22, 23, 24, 25 and 26 mg MJ− 1. After 8 weeks of feeding, the dietary P/E ratio influenced the specific growth rates, while survival, moult increment, moulting rate and moult interval were not affected by any dietary P/E ratios. The dietary protein levels had stronger influence on the specific growth rate whereas dietary lipid levels affected the length increments. The dietary P/E ratio also influenced the protease, lipase, super oxidase dismutase activities and the body composition of spiny lobster juveniles. Both protein and lipid in the whole body of the juveniles reflected the dietary composition. The total quantity of non-essential amino acids was higher than essential amino acids in the formulated diet and also in the body of juvenile lobsters. Results clearly indicated that 55% and 9% dietary protein and lipids, respectively with 26.6 g CP MJ− 1 can yield the maximum growth and digestive enzyme activities.

An evaluation of six dietary protein-to-energy (P/E) ratios was conducted to the early juvenile lobsters (Panulirus ornatus) by investigating the ratio effects on physiology, digestive enzyme activities, body composition, and amino acid profiles. Juvenile lobsters (0.25±0.01 g) were individually kept in aquaria and treated with six isoenergetic formulated diets of P/E ratios of 21.8, 22.5, 23.5, 24.6, 25.3 and 26.6 mg KJ−1. After 8 weeks of feeding experiment, the differentiation on dietary P/E ratios was found to have affected the specific growth rates, but not the survival, moult increment, moulting rate, moult interval and average daily moulting rate of juvenile lobsters. The dietary P/E ratio also influenced the protease, lipase, super oxidase dismutase activities, and body composition of juvenile lobster. The increase in dietary protein levels significantly affected the increase of the specific growth rate, while increased dietary lipid levels only affected the length increments. Both protein and lipid content were found in the whole body of the juveniles which reflected the treated dietary composition. Results indicated that a P/E ratio of 26.6 mg KJ−1 (55% dietary protein and 9% dietary lipids) can yield the maximum growth and digestive enzyme activities from among the studied diets.

“…Lobster hemolymph was taken in the ventral portion between the fourth and fifth walking legs by using a 1 mm syringe that is coated with EDTA as an anticoagulant (Atherley et al, 2020;Haryanti et al, 2017). The calculation of hemocytes was done by Hertika et al (2021) using a light microscope with 400 magnification.…”

Spiny lobster, a fishery commodity with important economic value, is often infested by Octolasmis sp. on their bodies, which causes stress conditions that lead to death. This study aimed to determine the anatomical pathology and hemolymph profile of spiny lobster infested with Octolasmis sp. in bottom cages. The method used was an observation, where 30 lobsters (weight 112.44 ± 24.63 g) were carried out in June–July 2022 at the Pesona Bahari Wongsorejo, Banyuwangi. Hemolymph profile and anatomical pathology data were analyzed, respectively, using the Independent T-Test and Kruskal-Wallis test (α = 95%). The results based on scoring data showed a very significant difference between infected and healthy lobsters (p < 0.01), characterized by the occurrence of tail flakes, lesions on the carapace, gill melanization, and the appearance of ulcers on the ventral abdomen. A very significant change occurred in the hemolymph profile of infected lobsters compared to healthy lobsters (p < 0.01). Total hemocyte count increased with high concentrations of granular cells, respectively 22.1–37.8 ´x 106 cells/mL and 63.75–64.5%, along with lobster damage, while hyaline cells decreased. This study showed that there was a change in anatomic pathology and hemolymph profile between infected and healthy lobsters.
