Abstract

Efforts are being made to reduce the high rate of cannibalism by using shelters in their maintenance of cages. Shelters are needed as a hiding place for moulting of lobsters, as well as expanding the living area. The aims of this study was to determine the behavior of spiny lobster including the frequency of molting and the level of cannibalism. This research took place in July–October 2021, at the Vocational School, IPB University. The design used in this research was a completely randomized design (CRD) using 4 treatments and 3 replications. The treatments in this study consisted of rearing of lobster with box-hole brick shelter (A), rearing of lobster with round hole brick shelter (B), rearing of lobster with pipe shelter (C) and rearing of lobster without shelter (K). The molting frequency of lobsters reared with box-hole shelters tended to be higher (60.0%) than other treatments but not significantly different (P>0.05). The percentage of cannibalism in lobsters reared without shelters / control (47.67%) tended to be higher than lobsters reared in batako shelters.

Abstract

Small island development requires a targeted approach so that it can be carried out according to the characteristics of the small island's social-ecological system. This study aims to identify the factors that influence the feasibility assessment indicators and the suitability of small island development sites based social-ecological system. The study was conducted using a survey approach to 24 experts in their respective fields who have relevance to the development of small islands in Indonesia. The results showed that there were 24 factors that could affect the indicators of the feasibility assessment and the suitability of the small island development location. Natural resources and ecosystems, facilities, human resources, accessibility, tourist sites, local wisdom, island governance, clean water, security, social capital, carrying capacity, and strategic position are the 12 most influential factors. Based on the priority analysis of SSE components, the most influential on the feasibility and suitability of small island development sites based on social-ecological systems are small island resources (1.00), associated small island ecosystems (0.81), small island users (0.60), socio-political-security-sovereignty (0.26), small island infrastructure (8.01%), and small island infrastructure providers (0.21). These factors and the level of influence of the SSE component are expected to be input in determining the indicators of feasibility and suitability of small island development sites based on social-ecological systems.

Abstract

Cannibalism is one of the factors contributing to the slow growth of lobsters. Cannibalism refers to the practice of one member of a species eating all or a portion of another member of the same species for nourishment. Cannibalism results in bodily deformities including missing fins and skin sores. Cannibalism is stimulated by the chemicals that are released from injured skin (amino acids). The level of cannibalism is said to be triggered by the container's mismatched color. This study set out to ascertain the behavior of lobster, including how frequently they molt and how much cannibalism occurs. A completely randomized design (CRD) with 4 treatments and 3 repetitions was employed in this study. It is well known that one factor in cultivating operations to boost output is the color of the tank. Color of the backdrop water in natural ecosystems to identify feed. In comparison to other treatments, lobsters raised with color tended to molt more frequently (69.33±0.14%) (P <0.05). In comparison to the treatment, lobsters raised in transparent/control containers had a greater percentage of cannibalism (36.00±0.33%) (P< 0.05)
