Abstract

Slow growth rate tends to be a challenge in the cultivation of spiny lobster (P. homarus) because it impact on long rearing periods and high operational costs, especially for feeds. Short-term starvation or fasting has known to allow the minimum feed usage without inhibiting biota growth, also improves digestive function, reduces the amount of water-soluble nutrient metabolites, and reduces operational costs. Spiny lobster (P. homarus) measuring 50.0 ± 10.0 g was reared for 6 weeks in floating net cages. Lobsters were fasted at intervals of 1 fasting day/1 day of feeding, 1 fasting day/2 days of feeding, and fed daily. Survival, growth, and feed efficiency of spiny lobster (P. homarus) were analyzed. Higher growth rate and energy retention were found in spiny lobster (P. homarus) reared with short-term fasting system.  Lower FCR also found in the same rearing system. Spiny lobster (P. homarus) body content indicate its ability to store nutrient in mucle and hepatopancreas in order to adapt to starved condition. Short-term fasting can improve growth and feed efficiency in spiny lobster (P. homarus) cultivation

Abstract

Diseases caused by pathogenic bacteria such as Aeromonas hydrophila are a major health concern. However, the use of red betel leaves (P. crocatum) can serve as a potential solution to this problem due to their antibacterial properties. This research aimed to study the antibacterial activity of red betel leaf extract (P. crocatum), the structure and character of the bacteria inhibited by the extract, and the bioactive components present in the leaves. The results of the disc test showed that the average zone of inhibition was 14.28 mm, while the MIC test results revealed that a dose of 100 mg/L could inhibit bacterial growth (bacteriostatic). Moreover, the crude extract of red betel leaf (P. crocatum) damaged the cell walls and cell membranes of A. hydrophila bacteria, thereby affecting their character and structure. The UV-VIS analysis of red betel leaf extract (P. crocatum) and FTIR analysis with 96% ethanol absorption indicated the presence of flavonoids, saponins, tannins, and alkaloids. These findings suggest that red betel leaves can be used as a natural remedy to fight bacterial infections caused by pathogenic bacteria such as Aeromonas hydrophila

Abstract

Spiny lobster is one of the potential commodities in Indonesia. On the other hand, there is still a problem to fulfill the export-ready stock of spiny lobster. Production engineering can be utilized as one way to overcome the existing problems. Laserpuncture is a new method of production engineering by utilizing low wavelength helium-neon light that can provide biological stimulation to living things resulting in accelerated development. Laserpuncture induction in crustaceans such as lobsters can be done on the eye stalk and ventral part. This study was conducted using completely randomized design method with 4 treatments and 5 repetitions of each treatment. The treatments given are differences in the duration of laserpuncture induction on female spiny lobster including A (2 seconds induction), B (4 seconds induction), C (6 seconds induction), and control (without induction). This study aims to analyze wheter laserpuncture affects Crustacean Hyperglycemic Hormone. CHH and gonad in female spiny lobster. Data analysis in this study was carried out qualitatively which included Crustacean Hyperglycemic Hormone A & B hormone, gonad histology, and survival rate. The results showed that treatment A (2 seconds induction of laserpuncture) on female spinny lobster had the most significant effect compared to other treatments.
