Abstract

Gold-mouth turban (Turbo chrysostomus L., 1758) is an important source of protein for coastal people in Lombok, West Nusa Tenggara, Indonesia. In order to acquire its seed production technique, research on the culture of the species was carried out since 2012. Feed source is a key concern when culturing animal, including turban snail. Growth of gold-mouth turban fed with seaweed Gracilaria sp., Ulva spp., and Kappaphycus alvarezii was evaluated. Each diet was randomly assigned to triplicate groups of 30 snail juveniles with an initial body weight and shell length of 4.65 ± 0.00 g and 24.55 ± 0.08 mm, respectively. After six weeks feeding trial, snails fed with Gracilaria sp. diet had significantly higher (P < 0.05) in final weight, final shell length, weight gain, specific growth rate (SGR) and food intake compared to snails fed with Ulva spp. or K. alvarezii diets.

Abstract

 A specimen of Parasesarma raouli (Crustacea: Brachyura: Sesarmidae) was collected from the mangrove area of Pulau Berang, Lingga, Riau Archipelago, Indonesia in Oktober 2014. This species previously was known only from Johor strait, Peninsular Malaysia. Its color in life is recorded for the first time.

Abstract

To compensate the decline of the populations of temperate anguillid eels, tropical anguillid eels become getting attention of East Asian eel market in recent years. Many eel farms have been established in Java Island to culture tropical anguillid eels intending to export the products to East Asia. Since eel farming is reliant on wild-caught anguillid eels such as glass eels, elvers and yellow eels, these eel seeds have been captured in various places in Indonesia. However, it is still unknown that how much of tropical anguillid eels are caught as seeds for eel farming. This study showed two different patterns of the commodity chains of eel seeds from both Sukabumi Regency and Bengkulu Province to the eel farms in Java Island. Official catch statistics on anguillid eels found in both Sukabumi Regency and Bengkulu Province were also analyzed on their features and problems underlied. Considering the sustainable use of anguillid eel resources and critical stances on exploitation of eel seeds from all over the world, the Indonesian government should take an immediate action for developing the national catch statistics on anguillid eel fishery as soon as possible.

Abstract

Indonesia is situated in the Coral Triangle region that has the world?s highest coral reef biodiversity. Therefore, coral reef monitoring needs to be conducted regularly to assess the condition of coral reef ecosystem for management purpose. There are several coral reef monitoring methods available such as the line intercept transect (LIT), point intercept transect (PIT), photo transect, belt transect and benthic towed-diver. In Indonesia, LIT and PIT are the most commonly used methods for coral monitoring. However, there is a main disadvantage when collecting data using these methods, that is scientific divers need to spend hours to input the data after dives. Here, we introduce an electronic logging instrument called Coral Input Data Instrument that helps to decrease the input data time by employing a look-up table system that simplifies data input process by replacing text with numerical coding. In addition, water quality data such as temperature, depth and visibility also are embedded in the electronic logging instrument. The instrument hardware consists of Arduino Mega 2560, keypad 4x3, LCD Module 16x2 character, real time clock, temperature sensor, pressure sensor, visibility sensor and micro SD card module. Arduino IDE 1.6.5 software is used to program the microcontroller. In this paper, we describe the design and implementation of the instrument in the field.

Abstract

Indonesia was recently ranked second on the list of countries producing plastic waste. Plastic can be degraded by thermal oxidation either with ultraviolet radiation and by mechanical to a very small size the size will be smaller. Degraded plastic with small sizes (<5 mm) measured has been micrometers known as microplastic. We took sediment samples on 07-18 May 2015 in EWIN 2015 cruise, which part of the contribution of Indonesian researchers for the International Indian Ocean Expedition-2 program, at 66.8 to 2182 m below sea level. Microplastic analysis from the sediment was carried out by using flotation methods. We found microplastic in 8 locations out of 10 sampling locations. We found 41 particles microplastic with a form of granules (35 particles) and fibers (6 particles). Most of microplastic particles were found at depths less than 500 m with 20 particles. The discovery of microplastic in the sediment from the sea of western Sumatra at a depth more than 2000 m, indicated that plastic, considered new developed materials (early nineteen centuries made), has invaded marine areas, including pristine areas. It confirms the statement that plastic waste has spread widely to different areas of the seas and oceans, including remote and mostly unknown areas such as the deep sea.
