MARINE RESEARCH IN INDONESIA (MRI) has been published since 1956 by Indonesia's oldest marine research institute, the Research Center for Oceanography of LIPI (Indonesian Institute of Sciences). MRI focuses on physical, chemical, biological, geological oceanographic as well as coastal management studies in the Indonesian seas and the adjacent Indo-Pacific region.

Abstract

Research on transplantation of Acropora microphthalma was conducted at Barrang Lompo Island reef edge of South Sulawesi from September to December 2002. The aim of this research was to know the successful rate of several coral transplantation methods for rehabilitation of coral reefs, covering the survival and growth rates. The methods used were framework earthenware (FE), iron stake (IS), dead coral tying (DCT), where the mother colony (MC) was used as control. These transplantation techniques were applied at five meter depth in two stations, north and south sites of the island. The survival rate for each method FE, IS, DCT and MC at the northern station was 85.71; 42.86; 85.71; 57.14%, while for southern station was 85.71; 85.71; 71.43 and 85.71%, respectively. The growth rates observed for each method at the first station were 2.18; 2.02; 1.40; 1.05 cm, and for the second station were 2.56; 2.21; 1.61; 1.04 cm, respectively.

Abstract

The main objective of this study was to determine reproductive strategy including major spawning season of tropical abalone (Haliotis asinina) from southern Lombok waters, Indonesia. Gonad bulk index, maturity stages and oocyte size frequency distribution were applied to document gonadal development and major spawning season. The results of this study show that H. asinina in southern Lombok waters displayed year-round spawning with a high proportion occurring in August - November, when gonad index dropped to a lower level and high proportion of partly spawned and/or spent ovaries occurred in the population. Gonad development and spawning in males and females occurred synchronously. The correlation between gonadal development and environmental factors are described and discussed.

Abstract

The use of cyanide particularly for fishing has caused concern for its impacts on aquatic marine life. This study was the first attempt to provide information on the effect of cyanide on tropical marine fish in Indonesia and aimed to determine the toxicity of cyanide to coral fish, Chromis viridis. The fish were exposed to 10,18,32,56 and 100 µg 1-1 of cyanide. These five cyanide concentrations were tested for 96- h period of exposure through a static-renewal. Cyanide was found to be very toxic to the fish. The 96-h LC50 of cyanide for juvenile of Chromis viridis was 41.3 µg 1-1. The toxicity of cyanide to C. viridis was 300 times stronger than that of the trace metal cadmium. Compared to milkfish fry (Chanos chanos), C.  viridis was more sensitive to cyanide. It is estimated that at concentration of 32 µg 1-1 cyanide does not show observable effect (NOEC) to C. viridis. Meanwhile the lowest observable effect of cyanide  (LOEC) to the fish is at a concentration of 56 µg 1-1.

Abstract

The FAO Code of Conduct for Responsible Fisheries states that conservation and management decisions for fisheries should be based on the best scientific evidence available. Studies show that most of Indonesias capture fisheries are either full or over-exploited. However, the fishery sector is still expected to contribute to the increase of Indonesias GNP through an increase in total catches. Furthermore, the current practice of using catch-effort data and Maximum Sustainable Yield models to inform Indonesia’s fisheries policies is flawed, putting sustainability and long-term profitability of Indonesias fisheries at risk. In this paper, the authors argue that to ensure the survival of Indonesias fish stocks and fisheries: fisheries policy must shift from development-oriented management towards management for sustainability. Furthermore, fisheries managers must accept that untapped resources may not exist or cannot be exploited profitably, and that any transfer of fishing effort between fishing grounds may contribute to collapse of local fisheries. Also, fisheries managers should change the management paradigm from MSY models to eco-system based management, wherein Marine Protected Areas should play an important role.

Abstract

During 1993 to 1996, reproductive aspects of Holothuria scabra, one of the commercially important holothurian species in Indonesian waters were studied, which involved populations of Ambon Bay (eastern Indonesian waters), Saugi Island (central Indonesian waters) and Lampung Bay (western Indonesian waters). Those studies were reviewed in this paper, not only to reveal general patterns of reproductive seasons of populations throughout Indonesian waters, but also to provide more knowledge on gonadaltubule-development that has been rarely investigated on Indonesian holothurians. The review showed that the development of gonadal tubules amongst populations of Indonesian H. scabra were similar. Those included that: tubules across a gonad grew for one single reproductive cycle, and each tubule had equal opportunity to release their gametes in the same spawning event. These features conformed to general characteristics of this species throughout the world, and were different from the proposed tubule recruitment model of Smiley (1988). Each observed population showed fluctuation on gonad index, and individuals with fecund and/or post spawning gonads were recorded in most sampling occasions, resulting in fluctuation of gonad index. This attribute gave clue to through-year spawning activity with more intense during one or two periods in a year.
