Abstract

This study was conducted to estimate the carrying capacity and population growth pattern of lola snail (Trochus niloticus) in Saparua Island. Samples were collected by strip transect method which was 100 meter long and 2 meter wide and were laid perpendicular to the coast line starting from the lowest tide level. Data were analyzed by Bhattacharya method to determine the age classes each individuals. The results showed that the population density was 620 individual/ha and the net reproductive rate of lola was 226 individuals and generation time was 2.88 years. Based on these this results, the carrying capacity which is the theoritical maximum density of lola snail population can be estimated to be 27.779 individuals per hectare and its population growth can be described by equation Nt = 27,779/e4.232-.,884. On the other hand the optimum population growth would be obtained when the population density equalled to 13.890 individuals in 2.25 years.

Abstract

Lola (Trochus niloticus) is one of the largest sea snails that lives in the shallow water in Eastern Indonesia and the Pacific. In Saparua Island (Central Maluku), lola population tends to decline due to its exploitation for industrial need. The aim of this study is to determine the reproductive potential of lola snail in Saparua Island, Central Maluku. Lola snails were collected from six locations i.e Booi, Haria, Ullath, Ouw, Itawaka, and Nolloth (03.290-03.800 LT dan 128.320-128.430 BT). In each location a strip transect 100 x 2 m was made perpendicular to the coastline started from the lower tide level. Lola snail populations were grouped into different age classes based on the shell diameter using Bhattacharya method. The reproductive potential of lola snail was analyzed by the value of the net reproductive rate. Gonad histology analyses were made by using paraffin methods and stained by Ehrlich’s Haematoxylin-Eosin. The results showed that the net reproductive rate of lola population is 226 individuals and its generation time is 2.88 years. The histological observations showed that the oocyte consist of proliferation, early developing and mature stages. Key words: Bhattacharya, oocyt, reproductive potential, Trochus

Abstract

Lola snail (Trochus niloticus) is one of the largest sea snails that live in coral reefsat Indo Pacific region and Indonesia including Saparua Island, the province of Moluccas. In a few recent years, the exploitation of lola snails has been increasing, so that the population of lola snails in nature decreases.. The yield of lola snail in Saparua Island and in the archipelagos of Banda from 1979 until 1992 showed a decrease from around 4 tons of dry shells to only around 0.25 tons. Furthermore, this research was aimed to estimate the size structure, age structure, and the sex ratio of lola snails population in Saparua Island, the regency of Central Moluccas. The sampling of lola snails used transects strip method.  Each transect was 100 m long and 2 m wide, which were divided into 10 segments of 10 m x 2 m. Transect was laid perpendicular to the coast line started from the lowest fall of the tides to the coast. The Bhattacharya method was applied for data analysis. The frequency distribution of shell diameter revealed that lola snails in Saparua Island consisted of nine size classes and two different age classes, which indicated that the population of lola snails in Saparua Island had two periods of spawning. Finally, from this research it could be concluded that the sex ratio of lola snail was 1:1.

Abstract

Lola (Trochus niloticus) is one of the largest size sea snail that live in coral reef at Indo Pacific region and Indonesia including Saparua Island. In a few recent years, lola population in Saparua Island tends to decline due to its exploitation for industrial need. This work aimed to estimate the density, biomass, and sistribution pattern of lola snail population in Saparua Island, Central Molluccas. Transects strip method was applied to collect the snail samples. Each transect was 100 meters long and two meters wide, which were divided into ten segments (10 m × 2 m), and laid perpendicular to the coast line started from the lowest tide level to the open sea. This study showed that average density of lola snail in Saparua Island is 620 individu/ha, with total biomass is 4.15 ton/ha. In Nolloth, lola snail have the highest density as well as the biomass, whilst in Ullath it shows the lowest density. The further down from the lowest tide level, the larger its shell diameter, and this relation can be expressed by y = –2.118 + 0.053x (r2 = 0.879). Morisita dispersion index revealed that the distribution pattern of lola snail is clumped.

Abstract

Assessment of conservation community perceptions has been an important aspect of wild species research. Harvesting the eggs of Moluccan megapodes has implications for the preservation of bird populations. This study aims to assess the perceptions of local communities living near bird nesting sites regarding the conservation of the endemic Moluccan megapodes (Eulipoa wallacei). The survey was conducted on 200 respondents from the productive age group (aged 15 to 65) using a proportionate stratified random sampling technique with a closed-ended questionnaire. The Likert scale was used to analyze perception data. Research findings indicated that the majority of the community supported the practice of harvesting eggs, even though they were aware that the birds were protected species. Community perceptions of conservation only focused on adult birds and their habitat rather than conserving bird eggs. Therefore, the perceptions of egg conservation must be considered when developing an effective conservation program. It was recommended to design a conservation program to increase local people’s awareness of the importance of Moluccan megapode conservation through sustainable egg harvesting.

Abstract

Maluku, an archipelagic region, has unique ecological features that support a high level of biodiversity. One such island in this region is Marsegu Island, located in the Western Seram Regency, which is recognised as a nature reserve and serves as a natural habitat for several species of snakes. This study identifies snake species and analyses habitat preferences on Marsegu Island. Data were collected using the Visual Encounter Survey (VES) method. A total of six snake species from four families were recorded, with Colubridae being the most dominant. Species showed distinct habitat preferences: Xenopeltis unicolor was often found under decaying wood in mangrove areas, while Ahaetulla prasina was associated with Cerbera manghas trees. Larger species, such as Malayopython reticulatus, were found in coral rubble, while Cerberus schneiderii preferred semi-aquatic habitats in mangrove mud. The results suggest that the distribution of snakes on Marsegu Island is strongly influenced by morphological and behavioral adaptations to specific habitat types. This study provides new ecological insights into snake species in mangrove ecosystems and highlights the critical role of habitat conservation in maintaining biodiversity on Marsegu Island.
