Post puerulus of scalloped spiny lobster, Panulirus homarus (Linnaeus 1758) rearing in floating net cage with different artificial diet

Abstract

Scalloped spiny lobster (Panulirus homarus) is an export commodity and high economic value in Asian-Pacific markets. The purpose of this study was to determine the best artificial feed for scalloped spiny lobster nursery in floating net cage. The nursery was conducted using 9 floating net cage 1 × 1 × 1 m in size with three treatments and 3 replicates. Three different artificial diets were used as treatments, i.e.: A, commercial pellet for grouper, with higher protein level (53.56%) but lower stability, less durable in water and will break within 3-4 hours after administration; B, commercial pellet for shrimp, with lower protein level (33.07%) but higher stability, will break within 10-12 hours after administration and C: pellet formula IMRAD Gondol, with middle protein level (46.51%) and higher stability, will break within 10-12 hours after administration.The post puerulus with total length 2.1±0.18 cm and body weight 0.28±0.04 g was reared at density of 100 ind/cage. A complete random design was used as an experiment design and analyzed by ANOVA. Feeding were given twice a day, 5% of biomass/day. The study was conducted for 4 months. The sampling of survival rate, total length and body weight were conducted every month and total haemocyte on the end of experimentwas measured. The result showed that there was significant different (P<0.05) for survival rate, but not significant different (P>0.05) among treatments for growth of total length and body weight. The best survival rate was on treatment C (39.0%), followed by treatment A (29.7%): and treatment B (16.7%). The number of haemocyte was almost the same between treatments with total haemocyte 250-285 x 104 per ml. From these results it can be concluded that pellet formula IMRAD Gondol can be used for rearing of scallop spiny lobster post puerulus.

Growth Performance of Scalloped Spiny Lobster (Panulirus homarus) Given Artificial Feed Based on Chicken Eggs Hatching Waste

“…The use of energy derived not from feed but obtained from consuming peers is suspected to be an additional energy source that supports growth. FCR values from this study showed values that were the differ as the results of Slamet et al, (2020) research, namely the FCR values of lobsters fed artificial feed ranged from 3.0-3.20.…”

“…Figure 6 shows that the highest average live survival value of scalloped spiny lobster was found in the P1 treatment with a value of 100%, followed successively by the P2 treatment of 75%, P3 of 67% and the lowest survival value was found in the P4 treatment with a value of 58%. In general, the percentage of survival rate in this study was higher than that of Slamet et al, (2020), which ranged from 16.7% -39% for 120 days of lobster rearing. The results of the analysis of variance showed that the results of adding chicken egg hatching waste to granulated lobster feed had a real effect on the survival of scalloped spiny lobter.…”

Fish and shrimp hydrolysate as additives in lobster feed formulation: effect on growth, survival, feed consumption of spiny lobster (Panulirus homarus)

“…Lobsters in grow-out net cages mainly used trash fish for feed. Other fresh feeds are crustaceans and mollusks [8]. From this feeding habit, spiny lobsters are characterized as opportunistic carnivores, which utilize high protein, low lipid, and moderate to high levels of carbohydrates food as their main feed [9].…”

The Development of Lobster Puerulus (Panulirus Ornatus and P. Homarus) in Captivity Environment

“…The development of lobster puerulus... (Ishaaq Saputra) are abundant in certain Indonesian waters (Chan, 2019;Setyanto et al, 2019;Priyambodo et al, 2020). Lobster farmers have been cultivating them for decades in small quantities using traditional methods by feeding them trash fish, but research on the development of prepared diets continues to progress (Kurnia et al, 2017;Marchese et al, 2018;Ridwanudin et al, 2018;Amali & Desi, 2020;Arumugama et al, 2020;Prayitno et al, 2020;Nankervis & Jones, 2022). It has been reported that lobster juveniles can achieve market size after nine months of post metamorphic culture.…”
