“…The ratio of shelters also affects the survival of lobster rearing; the use of shelters of 4:5 is better than the ratio of lower or higher [15]. The use of shelters in lobster farming can reduce cannibalism; however, the size and material of the shelter greatly influenced the final survival rate ( [16] [17]).…”

The addition of the right combination of shelters to lobster farming can reduce cannibalism and increase survival rates. This study aims to find a suitable shelter combination for Scalloped spiny lobster reared in a fiberglass tank. The study was conducted in 12 fiberglass tanks 1 m3 in volume, with an initial lobster puerulus weight of 0.26 ± 0.024 g and a density of 100 /tanks. The combination of shelters tested is roster brick (A); shading net (B); roster brick and seaweed Gracillaria sp. (C); and shading net and seaweed (D). The parameters observed were survival rate, body length, body weight and hemocytes. Results showed that the best survival rate at treatment C (36.3 ± 10.54%), followed by A (33.3 ± 5.77%), D (25.0 ± 5.57), and lowest at B (14,3 ± 4,04%) (P<0.05). The final body weight and total length did not significantly different (p>0.05). The highest total hemocytes at treatment C (616.5±67.254 cell/ml), followed by A (583.4± 59.434 cell/ml), D (572.6±56.324 cell/ml), and lowest at B (459.6±45.344 cell/ml). The shelter combination of roster brick and seaweed (Gracillaria sp.) is better than another treatment because it can produce a better survival rate.

“…As a result, the utilization of feed energy for lobster growth, including the synthesis of immune material, can be disrupted. Hemocytes have an important role in the crustacean immune system, which can be used as an assessment of health through its characteristics and defense activity against infectious agents [34,35].…”

The cultivation of multilevel floating net cages (MFNC) systems is believed to be able to increase production capacity without increasing the horizontal area of the cultivation area. Research on the effect of using MFNC on the growth and health performance of Spiny lobsters and Snubnose pompano has never existed, so a study was conducted with the aim of comparing the growth and health performance of spiny lobsters and Snubnose pompano in floating net cage (FNC) and MFNC cultivation systems. The research method used was a field experiment with a comparative analysis of spiny lobsters and Snubnose pompano cultivation with different cultivation systems, namely the MFNC and FNC systems with 3 replications. The rearing lasted for 2 months and was fed trash fish as much as 5% of the biomass every day. Parameters of spiny lobsters and Snubnose pompano growth performance observed included weight growth, carapace length growth, total length growth, and specific growth rate. The health status of spiny lobsters observed quantitatively was the total hemocytes counts and hemolymph glucose levels, and Snubnose pompano by counting erythrocytes and blood leukocytes. The results showed that there was no difference in growth performance, survival and health status of spiny lobsters and Snubnose pompano reared using MFNC and FNC systems based on paired two sample for means, because p value > 0.05 for all growth parameters survival and health status. Thus, the use of a multilevel floating net cage system in lobster cultivation can increase FNC productivity and be efficient in optimal space utilization and does not affect water quality, especially the parameters of temperature, pH, dissolved oxygen and salinity. There were no significant differences in the growth performance, survival, and health status of lobsters and Snubnose pompano when reared using the MFNC and FNC cultivation systems.

“…Stress in lobsters is characterized by changes in the amount of THC concentration, PO activity, and phagocytic activity. The high number of hemocytes in hemolymph causes the body's inability to respond, thus causing a reverse effect to become an immunosuppressor that can reduce the immune system (Ekawati et al, 2012;Djai et al, 2017).…”

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.
