Abstract

Highlight ResearchLong-term maintenance of Filopaludina martensi martensi in artificial conditions (local tap-water and food).Observation of breeding behaviour of F. m. martensi.Observation of birth and development of the juveniles. AbstractFilopaludina martensi martensi Frauenfeld 1865 is an aquatic Viviparidae gastropod found in Thailand, and throughout Southeast Asia. It is popular in the local cousin, a vector of food-borne trematode infections, and used as a bio-indicator of heavy metal contamination, bio-control agent against Bithynia siamensis Lea 1856, and a way to reduce the total organic matter content from faeces and feed residue during Clarias sp. catfish and Nile tilapia aquaculture. The study aims to establish a protocol for breeding F. m. martensi snails in artificial conditions. The snails were maintained in laboratory conditions. The animals gave birth (3 - 4 juveniles) every month. Inflatable, for several hours after the birth, transparent lightly bluish (5 - 6 mm in diameter) spheres are released in which the fully mature juvenile moves, and leaves several hours later after the sphere breaks. All juveniles studied here die after 2 - 3 months failing to grow into a reproductive adults. F. m. martensi is an attractive animal that regardless of the current difficulties to maintain and grow its juveniles may be popularised in the ornamental fish trade, and a possible laboratory model animal.

Abstract

Highlight ResearchThe feedback harvest control rule resulted in the lowest allowable biological catch estimation than the surplus production models.  The feedback harvest control rule adapted the recent years of historical catch data.The surplus production models might result in over or under catch estimation, not considering the recent data.This multispecies fishery could not provide species specific data as surplus production models required; therefore, it might be better to use the feedback harvest control rule that has been validated for multispecies fisheries. AbstractScads fishery in Blitar waters is a multispecies fishery applying harvest control rules (HCRs) from conventional single-species approaches which technically, may not be applicable to employ in such mixed-species data composed from the multispecies fishery. The feedback HCR is an alternative validated harvest control rule that can be applied for a multispecies fishery. The aim of this study was to technically compare the application of the feedback HCR and conventional single species approaches in terms of estimating the future allowable biological catch (ABC). Therefore, in this study, ABC was estimated by applying three HCRs, the feedback HCR, and two conventional HCRs which was based on single-species approaches applying surplus production models, Schaefer Model and Fox model into catch and effort of scads fisheries data series of 2011 – 2020. The results showed that the ABC estimation of the feedback HCR was a half lower than that of both conventional models. It was biologically safer to apply the feedback HCR to set the annual total allowable catch (TAC) than the other two HCRs. The feedback HCR presented an initial step toward sustainably managing multispecies fisheries while dealing with data-limited conditions.

Abstract

Highlight ResearchThis is the first report of the occurrence of gregarine species in Peninsular Malaysia.The information of these findings will lead to the identification of species using genetic analysis.This information can help to solve the cultured problem of the Macrobrachium rosenbergii industry worldwide. AbstarctStudies on the parasite of prawn are likely to be important due to the commercial value of the prawn. Investigation study about gregarine parasites of M. rosenbergii in Malaysia is still lacking. Objective of this study is to determine the occurrence of gregarine parasites in shrimp, M. rosenbergii from Setiu Lagoon, Terengganu. The study was done specifically to observe the prevalence and the mean intensity of the parasites which include the morphological prevalence and parasitological study. Prevalence of the parasites in this study is 42.4% with 95% Cumulative Index (CI) 25.6% to 59.3% and value of Odd Ratio (OR) is 0.74 (CI = 0.29 to 1.88). Two structures of the gregarine which is gamont and syzygy found in this study are closely related to morphology characteristic of gregarine in the previous report.

Abstract

Highlight ResearchThe most significant morphological variation was the snout length and caudal peduncleT. lepturus from the coast of Pati and Cirebon have a high morphometric character resemblance and possibly are members of the same populationT. lepturus in Demak waters formed a separate population group from T. lepturus from the coast of Pati and Cirebon, however still in the same species AbstractHairtails (Trichiurus spp.) are economically important fisheries resources and have become an export commodity. In Indonesia, there are several hairtail species; however, each species distribution is not yet certainly known. This study aimed to identify and determine the morphometric and meristic character of the hairtail from the northern coast of Java, Indonesia. Fish specimens were obtained from fishermen catches in the north coast of Pati and Demak (Central Java) and the northern coast Cirebon (West Java), which captures the fish in less than one-week fishing operation. Fish samples were grouped based on morphological similarities identified in previously published works. After that, 22 morphometric and four meristic characters were measured and counted. Principal Component Analysis and Discriminant Analysis were used to analyze morphometric data, while the meristic data were compared to the available published works. The hairtail caught at the northern coast of Java was long, flat, silvery in color, and had a sagittal crest, with the fin formula being D.III.125-134, P.I.10, and A.I.98-104. According to the morphological and meristic characters, the hairtail caught at Java's northern coast was identified as Trichiurus lepturus. The most significant morphological variation was the snout length and caudal peduncle. The PCA and scattergram analyses showed that T. lepturus from the coast of Pati and Cirebon have a high morphometric character resemblance and possibly are members of the same population.  T. lepturus in Demak waters formed a separate population group from T. lepturus from the coast of Pati and Cirebon, however still in the same species.

Abstract

Highlight ResearchWhite shrimp (Litopenaeus vannamei) challenged with IMNV and different stocking densitiesThe water quality parameter values are getting worse along with the increase in stocking densityWhite shrimp THC value decreased with increasing stocking density and IMNV challenge testThe development of the IMNV increased with an increase in stocking density seen from the speed and percentage of the appearance of the clinical symptoms and histopathology results AbstractIncreasing in stocking density of shrimp affects the physiology and behaviour of their moving space. The health condition of shrimp is influenced by feeding, growth, and its susceptibility on disease. The aim of this study was to determine the development of immune response in relation to density and the presence of IMNV infection. This study used a completely randomized design (CRD) at density of 100 shrimp.m-2, 200 shrimp.m-2, and 400 shrimp.m-2, with three replications in each treatment. The shrimp used was 5,02±0,26 g and the virus infection was exposed orally. This research was facilitated at the Disease Research Centre Laboratory of Central Proteina Prima Company, Pasar Kemis, Tangerang for 30 days. The results showed that the Total Hemocyte Count (THC) in hemolymph of shrimp had different values between negative controls and challenged IMNV. The lowest THC value was found at a density of 400 shrimp m-2 (3.00x106ml-1). While the highest THC value was at a density of 100 shrimp.m-2 (4.75x106ml-1). This result is supported by the increasing value of water quality parameters along with the increasing density of shrimp. Histopathology changes on skeletal muscle and lymphoid organs confirmed that the development of IMNV infection was faster at high shrimp densities.

Abstract

Highlight ResearchThe value of Leaf Area Index (LAI) and Normalized Different Vegetation Index (NDVI) have a strong relationship.Estimated mangrove leaf biomass and carbon stock in mangrove can be known through the Leaf Area Index (LAI) value.Each mangrove pixel can absorb the different carbon.Increasing the diameter of the tree trunk shows the more CO2 absorbed by the tree.AbstractWorldwide global warming occurs because of increasing carbon dioxide (CO2) in the atmosphere. Segara Anakan, the largest mangrove forest in Java Island, has the highest potential as a carbon sink in the tropics. This study aimed to quantify the area and density of mangrove forests in Segara Anakan and to estimate their potentials as carbon sink based on Sentinel-2A imagery. In this study, data from Sentinel 2A satellite imagery was processed and validated with field survey results. The results showed that Segara Anakan had mangrove forests covering an area of 5,481.64 ha in 2019 with the sparse density covered 706.92 ha, medium density covered of 2,526.80 ha, and high density covered 2,848.60 ha. The results of mangrove density were validated using Table Confusion Matrix and using correlation coefficient value (r) by comparing field measurement and Normalized Difference Vegetation Index (NDVI) algorithm. The accuracy for mangrove density was 86.92% with r-value 0.85. Mangrove in Segara Anakan has the ability to absorb 8.56 Mega gram of carbon per hectare. Segara Anakan mangroves have the potential to absorb high level of carbon, so we should maintain their sustainability.

Abstract

Highlight ResearchThe homogenization process affected the particle size reductionThe homogenization process using both High Speed Homogenizer and Ultrasound had a smaller particle size and the highest efficiency in encapsulation AbstractArthrospira platensis contains a high concentration of carotenoids mainly 80 % β-carotene. The use of β-carotene in functional food and nutritional supplements was constrained by its lack of chemical and physical stability. Therefore, efforts were needed to protect carotenoids from damage by using an encapsulation system. The emulsion preparation before the encapsulation process had an influence on the stability of the oil-in-water emulsion. Various methods were used to prepare emulsions, such as high shear homogenizers (HSH) and ultrasound (US) treatment. The homogenization step was critical because it influenced the chemical stability of any encapsulated compounds. The purpose of this work was to generate nanocapsules of β-carotene with minimum carotenoid degradation, high efficiency of encapsulation, and small particle size, with variation in the homogenization process. This study consisted of 5 treatments, including the homogenization processes used HSH 24.000 rpm for 90 s ; HSH 24.000 rpm for 60 s, amplitude 55 % for 120 s ; amplitude 94 % for 138 s ;  amplitude 55 % for 138 s ;  and  amplitude 55 % for 120 s . Each parameter was analysed by ANOVA followed by Tukey pairwise comparisons with 95% confidence level and p<0.05. The particle size was influenced by the emulsification process, such as homogenization treatment, homogenization time, amplitude, and time of sonication. The sample that was homogenized using both HSH and US had a smaller particle size and the highest efficiency in encapsulation than others. The combination of homogenization process could decrease particle size.

Abstract

Highlight ResearchPoint Intercept Transect Method (PIT) and Underwater Photo Transect (UPT) to monitor coral cover was comparedPercentage of hard coral cover was analyzedThe average difference of the percentage of hard coral cover obtained from the PIT and UPT was analyzed AbstractCoral reef ecosystems are vulnerable to damage and extinction. Therefore, it is imperative that, as part of conservation, their conditions are monitored using straight forward or easy-to-use methods. The research was intended to compare the effectiveness of using Point Intercept Transect (PIT) and Underwater Photo Transect (UPT) methods in calculating percent hard coral covers. It was conducted at six sites in Karimunjawa Islands, Indonesia: Cemara Besar, Cemara Kecil, Taka Malang, Tanjung Gelam, Menjangan Besar, and Menjangan Kecil. At each site, photographs of coral reefs were taken in two ranges of depths, shallow (3–6 m) and deep (9–12 m), along the length of the predefined transects (100 m for PIT and 50 m for UPT). In UPT, the photos were taken using a 58 x 44 cm frame. Fifty photo frames were collected then processed using Coral Point Count with Excel extensions (CPCe) 4.1. The results showed that PIT and UPT produced different percentages of hard coral cover at each site, with the most significant difference found in deep waters of Menjangan Besar (45.27%) and the least one in deep waters of Menjangan Kecil (0.08%). Overall, the difference in percent covers was averagely 9.79 percentage points, which is still categorized into small. Both methods have their own advantages and disadvantages. However, UPT is preferable because its results can be reanalyzed, especially the identified coral reef species.

Abstract

Highlight Research Anthropogenic factors are the main cause of damage to mangrove ecosystems Restoration is a method for ecosystem restoration Restoration success is seen from the physical, chemical, and biological parameters Phytoplankton is a bioindicator of water quality The abundance of mangroves can explain the state of an ecosystem   Abstract Mangrove ecosystems in Sine and Pancer Cengkrong had degraded due to land-use change and restoration has been carried out over a few year on the damaged location. This study was conducted to evaluate water quality of mangrove ecosystems at both locations based on physical, chemical and phytoplankton parameters as bioindicators. The evaluation of Cengkrong Mangrove was carried out at 4 different locations based on different periode of restoration, namely restoration of 2008-2009, 2013-2014, natural mangroves, and 2005 succession mangroves, whereas there was only one sampling site at Sine mangrove namely 1998-2008 restoration. The physico-chemical parameters measured include water temperature, air temperature, conductivity, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), salinity, nitrate, and orthophosphate. Phytoplankton data was used to measure, trophic diatom index (TDI) as an indicator of water nutrition status, and pollution tolerant value (%PTV) as an indicator of organic pollution. The results showed that the water quality at all the study locations met the Indonesian Ministry of Environment Regulation No 51/2004, except nitrate and phosphate. Based on the TDI index, mangrove in Sine, Cengkrong 2013-2014 restoration, and 2005 succession mangroves were categorized as hyper-eutrophic, natural Cengkrong mangroves were categorized as eutrophic, and 2008-2009 restored Cengkrong mangroves were categorized as meso-eutrophic. Based on the %PTV index, in the Sine mangrove, 2013-2014 Cengkrong restoration, and 2005 succession mangroves were classified as high levels of organic matter pollution, while in the Cengkrong 2008-2009 restoration and natural Cengkrong were classified as a moderate level of organic pollution.

Abstract

Highlight Research 1. Metallothionein is a protein found in seagrass and functions to bind to heavy metals so as not to damage the seagrass body tissue   Abstract Lead is a very dangerous heavy metal for organisms because it is carcinogenic, can cause mutations, takes a long time to decompose and has unchanging toxicity. This study on the seagrass Cymodocea serrulata aimed to determine the metallothionein expression quantitatively using the Elisa (Enzyme-Linked Immunosorbent Assay) method and describe the surface structure of C. serrulata roots, rhizomes, and leaves that were exposed to lead using SEM and EDX Mapping methods. The results showed that metallothionein was abundant in C. serrulata tissues (leaves>roots>rhizomes) in both South Bangka and Ketawai Island. SEM showed changes in the morphology and cell size of C. serrulata exposed to lead. EDX and Mapping showed the substance elements found in seagrass tissue. Pb was detected in C. serrulata roots (0.22%) and leaves (0.6%) in South Bangka. This indicates that the seagrass plants are able to absorb heavy metals into their body tissues.
