Abstract

Persistent organic pollutants (POPs) have been identified as representing a serious threat to the marine environment and received formal attention by nations worldwide including Indonesia as one of the signatories and ratified countries for the Stockholm Convention. Due to their emerging issues, the study of POPs at all aspects is needed. Therefore, this paper attempts to review characteristics and toxicological properties of POPs, the current status of POPs National Implementation Plans (NIPs) in Indonesia, and propose future directions of POPs study in Indonesia from basic research such as monitoring of POPs distribution in Indonesian seas to applied research for example study of POPs alternative compounds.

Abstract

Coral reef ecosystem is one of the coastal marine ecosystems in tropical waters. Coral reef ecosystems are vulnerable to damage mainly due to environmental factors. A fairly popular event of coral reef damage is coral bleaching. Mass coral bleaching is generally caused by changes in Sea Surface Temperature (SST). The condition of corals that have bleaching is different from the condition of corals that have died. The recovery process from coral bleaching phenomena can be effectively carried out if the surrounding environment is supportive and sea surface temperature return stable. The phenomenon of coral bleaching is a real indicator of the environmental stresses that occur on coral reefs. This paper will explain about coral bleaching, the factors that cause coral bleaching, and whether the bleaching coral reefs mean alive or dead.

Abstract

In 2006, a tumult arose in the world of fisheries. A controversial paper titled “Impacts of biodiversity loss on ocean ecosystem services” by Worm et al. (2006) was published in Science. The paper was sensational since it alluded to a prediction that global populations of marine fish (finfish and invertebrates) will be 100% collapsed by 2048. The paper was written by a group of marine ecologists and economists in which Boris Worm from Dalhousie University Canada led the authorship. After the paper was published, the issue of fish disappearance in 2048 became hot topics in the world’s mass media. In fact, the Worm et al. paper triggered the debates among researchers. Over time the debates heated up. Surprisingly, a reconciliation took place in 2009, marked by a collaboration between Worm’s team and his critics, writing another paper in Science. The present essay reaffirms the invalidity of the global collapse prediction in 2048 as revealed by many researchers. It is also shown that the Worm et al. paper did not state that all fish will disappear and through the joint paper in 2009, Worm and colleagues have indirectly rectified the prediction already.

Abstract

Consuming contaminated seafood can be potentially harmful for human health, especially for coastal communities. For this reason, a health risk assessment is very important to determine the safe limit for consuming seafood. Several stages in this assessment are; (i) direct comparison with the standard/maximum limit of heavy metal concentration determined by each country or international organization, (ii) determination of the maximum amount of seafood that can be consumed by adults per week, (iii) determination of the Estimated Daily Intake (EDI), and (iv) determination of the Target Hazard Quotient (THQ) of each metal and the Total Hazard Index (HI) for the combined metals.

Abstract

Microplastic is a threat to the survival of organisms on terrestrial and ocean. Microplastic waste accumulation from human activities will accumulate in the environment. The presence of microplastics in the environment is a problem because plastics are persistent. Plastics often contain chemicals that are potentially toxic and carcinogenic. They are consumed by organisms that will affect aquatic life. Plastic waste in the ocean will directly or indirectly poison the marine biota, damaging coral reefs which will further damage the balance of the marine ecosystem. The process of decomposition of plastic waste into microplastics takes hundreds of years through physical, chemical, and biological processes. The problem of microplastic waste can be overcome by biotechnology approaches. One of the strategies to control microplastic pollution is remediation technology by utilizing the potential of indigenous bacteria that grow in their natural environment. Furthermore, the use of bioremediation agents from other microorganisms has been carried out among them, using Fungi and Actinomycetes. The potential of microplastic degrading microorganisms in sea waters has not been done in depth, especially studies in improving the ability of microorganisms to degrade microplastics. The purpose of writing this review is to review the potential of microplastic degrading bacteria originating from marine waters.

Abstract

Physalia physalis is one of the jellyfish believed to be responsible for a significant proportion of jellyfish attack cases in the world. As one of the most dangerous members of the Cnidarian in the sea, P. physalis has a sting that can paralyze their prey. To humans, the sting can cause cardiotoxic, neurotoxic, musculartoxic, and hemolytic effects. P. physalis has different biological characteristics than most organisms. For example, an individual of P. physalis actually is a colony consisting of four groups of individuals who have different structures and functions. The arrangement of the colony has a complex structure and shows a polymorphism. P. physalis is a pleustonic organism because they live on the surface of the water. P. physalis still leaves many mysteries to scientists. For example, the life cycle of a P. physalis is not yet fully known. Besides, the diversity of P. physalis also still leaves questions among scientists. Some believe that P. physalis is monotypic, while others suspect there is cryptic diversity. Therefore, the study of P. physalis is very interesting, especially under the issue of climate change. Many scientists believe that jellyfish get benefit from increasing sea temperatures, so the population is predicted to increase. The high population of P. physalis threatens the sustainability of fish stocks in the ocean, mainly due to P. physalis are productive predators of fish larvae. This paper aims to provide information on the biological aspects of P. physalis, which are still limited in Indonesia.

Abstract

One of various shellfish in Indonesia waters that has high economic value is genus Anadara, especially as an edible marine species. Anadara is traditionally known in the trade as blood cockles. There are approximately 100 species of blood cockles in subfamily Anadarinae, the largest member of family Arcidae. Systematic of Anadarinae still does not provide certainty until now, including because there are many variations between species. Anadara, and Arcidae, in general, is one of the most abundant families of mollusc in tropical waters, and spread out in almost all of the coastal waters and found in the basis of subsystems. Its growth will be better on soft mud substrate than sandy mud substrate. Blood cockles are known as a filter feeder that feeds using gills on plankton, especially on phytoplankton. The demand for blood cockles is increasing, thus encouraging production efforts that do not only rely on harvesting from nature but through cultivation also that has been done in several places in Indonesia, such as in Sumatra and Java. This paper discussed taxonomy and classification, morphology and anatomy, habitat and distribution, reproduction and aquaculture, diet and feeding habit, and economic value of blood cockles.
