Abstract

Highlight Research The methanolic extracts of  salinaand B. braunii contained alkaloids, steroids, triterpenoids, flavonoids, and saponins. Chlorophyll a, chlorophyll b, and carotenoids were most abundant in the ethyl acetate extracts of salinaand B. braunii. The maximum total phenolic content was observed in the n-hexane extract of  salina(61.28 mg GAE/g sample) and the ethyl acetate extract of B. braunii (46.94 mg GAE/g sample). The n-hexane extracts exhibited the highest antioxidant activity, whereas saponins were most abundant in the methanol extracts. Abstract Microalgal species such as Dunaliella salina and Botryococcus braunii are reportedly rich in natural antioxidants and phytochemicals. This study aimed to determine the phytochemicals and the antioxidant activity of D. salina and B. braunii. Microalgal samples were obtained from the Brackish Water Cultivation Fisheries Center (BPBAP), Situbondo, East Java. The extracts were prepared using the multilevel maceration method. The antioxidant activity of the algal species was analyzed using 1,1-diphenyl-2-picrylhydraxyl (DPPH). Quantitative analysis revealed that D. salina and B. braunii contained antioxidants, indicated by the appearance of yellow spots on the purple background of the TLC plate. The n-hexane extract of D. salina exhibited the highest antioxidant activity with a half-maximal inhibitory concentration (IC50) of 443.28 ppm, 61.28 mg GAE/g sample of total phenolics, 0.106 mg/g of chlorophyll a, 0.165 mg/g of chlorophyll b, and 1,697 mol/g of carotenoids. In contrast, the ethyl acetate extract of B. braunii exhibited the highest antioxidant activity with an IC50 of 634.55 ppm, 46.94 mg GAE/g sample of total phenolics, 18.146 mg/g of chlorophyll a, 12.592 mg/g of chlorophyll b, and 4573 mol/g of carotenoids. The microalgal species used in this study exhibited extremely weak antioxidant activity.

Abstract

Highlight Research The endolithic bioeroders were identified. Cocconeis sp. was new for the science of euendolithic bioeroder of Scleractinian coral. SEM revealed Cocconeis sp. etch and bore of coral skeleton. Pennate diatom was present on coral cavities.   Abstract Laminar coral, Montipora, contributes to the coral reef ecosystem. The laminar life form is usually used by juvenile reef biota to shelter and prey. In an intertidal area, such as Pantai Kondang Merak, these corals are susceptible to erosion caused by mechanical and biological forces. Strong current or other anthropogenic activity may break coral colonies into pieces. Also, some grazers from reef fish and bioeroder potentially weaken coral structures. This study aimed to find the effect of biological agents from Bacillariophyceae, such as Cocconeis diatom, on the bioerosion process in laminar coral, e.g., Montipora. Ten montiporid corals from Pantai Kondang Merak were observed to find bio-eroding activities. Each coral colony was divided into 12 parts and photographed to record signs of bio-erosion on coral surface. While observing microborers, a 2x2 cm of the coral surface was observed using Scanning Electron Microscopy (SEM). SEM revealed that a frustule of Cocconeis sp. was found inside aragonite laminar coral from Pantai Kondang Merak. Cocconeis naturally grows on the coasts of tropical oceans as benthic organisms. They are reported as living attached to many substrates' surfaces and within the substrate as euendolith. This study revealed that Cocconeis sp. lived inside the coral skeleton as micro bioeroder by attaching their valve in coral aragonite. Further work needs more observations of another potential euendolith diatom living inside the coral and to build new information on their mechanism of bio-eroding process in more detail.

Abstract

Highlight Research The very first attempt to investigated and revealing biodiversity of crustacean crab in coral reef ecosystem at Tidung Island, Indonesia Conservation area (Tidung Kecil) has more abundant crab species than tourism area (Tidung Besar). A microhabitat that suffers anthropogenic pressure may alter the composition of crustacean biodiversity, especially in crab group. Different characteristics and complexity of coral habitat affect the dynamics of cryptic crustacean communities   Abstract   Recent studies have been widely carried out on the important role and ecological function of coral reefs. However, little attention has been given to small and cryptic crustaceans organisms living within different microhabitat in dead corals. This study aimed to reveal the diversity of crustaceans that inhabit dead corals in Tidung Islands, Indonesia. A total of 134 individuals from 41 species in 13 families were recorded within eight dead corals taken from two different sites. Furthermore, the species identified from Tidung Kecil were significantly different and more diverse than Tidung Besar. It was suggested that differences in anthropogenic pressure between Tidung Besar and Kecil might have an important role in the spread of crab crustaceans' organisms. Xanthidae from infraorder Brachyura were observed to be the most dominant family, while Galatheidae and Porcellanidae from infraorder Anomura spread almost equally in both sites. Additionally, Psaumis cavipes and Chlorodiella nigra were species with the largest contribution of crab crustaceans' communities in the death of coral's ecosystem in the Tidung Islands. This result indicated that dead corals might play a key role in supporting and providing a habitat for crustacean cryptic.

Abstract

Highlight Research Sulfuric acid soil causes extreme acidity of the water (pH<3) and is unsuitable for fish culture Well management for sulfuric acid soil reduce the high risk of soil and water acidity The use of an appropriate combination of different liming is better than the single material to solve the very low pH Combination of dolomite and hydrated lime increased the pH and alkalinity   Abstract The application of liming material should consider the amount and quality of chemicals related to cost expenditure and target of expected soil properties since it is usually done with an incorrect number's estimation and expected soil-water quality which produces unsuccessful results. This study aimed to analyze the effect of different percentages from each combination of dolomite and hydrated lime (DH); DH1 (75:25), DH2 (50:50), and DH3 (25:75), which used five replications to the soil and water quality. The soil samples were taken from the earthen pond of semi-intensive tilapia fish (Oreochromis niloticus) culture in Lat Bua Luang, Rangsit, Thailand, placed into 50 plastic pots (volume = 1.5 L), and mixed with lime of different compositions. Based on the results, the mixture of dolomite and hydrated lime (DH) increased the soil and water pH into the desirable ranges (7.4-8.6). The alkalinity of DH treatments was not higher than that of the single dolomite (DA) or hydrated lime (HA). However, the value was still sufficient (>75 mg/L as CaCO3) to buffer water quality changes. Several depletions of the toxic materials (total aluminum, iron, and manganese) caused by sulfuric acid (FeS2) had been observed in combination treatment, especially in DH1. On the contrary, the essential base cations, calcium, and magnesium increased beyond the single treatment, either dolomite (DA) or hydrated lime (HA). A combination of dolomite and hydrated lime (DH1) as an alternative treatment to remedy aquaculture ponds in acid-containing soil is suggested in terms of efficiency and possible cost-effectiveness.

Abstract

Highlight Research We found 16 species of mollusks with a total of 15 species from the gastropod class and 1 species from the Bivalvia class bivalves in the silvofishery ponds, recording a total of 369 individuals. The density of mollusks in July in pond I was 3.6 ind/m2, while it was 10.66 ind/m2 in pond II. The mollusk diversity index in October after rehabilitation was included in the high diversity category because the value of H' was 1.6 - 3.0. Pond I has a diversity index value of 1.89 and pond II 1.82. The value of C-organic concentration in both ponds ranged from 3.00% to 5.72%, which is the optimum level for mollusk growth.   Abstract Silvofishery is a system that combines mangrove and fishery to protect mangrove ecosystems and restore their functions, one of which is as a habitat for macrozoobenthos. Investigate the mollusks and mangrove density. Mollusk sampling was carried out on sub-plots measuring 1 x 1 m² in the mangrove vegetation transect, and mangrove density was measured by counting the number of trees directly on all of the mangrove species at two silvofishery ponds. A total of 16 species of mollusks were found at the observation site, consisting of gastropods and bivalves. The density of mollusks in July was 20 ind/m2 in pond I, while it recorded 9 ind/m2 in pond II. In October, after pond II rehabilitation, the density was inversely proportional to July, and the highest density was found in pond I at 10 ind/m2, while pond II measured 9 ind/m2. After rehabilitation, the index value H' decreased in pond I and pond II from 2.82 and 2.98 to 2.52 and 2.68, respectively. The mangrove density was 887 ind/ha in pond I and 686 ind/ha in pond II. The substrate in both ponds was clay. Nitrate concentration values "‹"‹in the substrate in both ponds ranged from 0.27% to 0.29%, phosphate recorded a percentage of 0.07–0.09%, and C-organic ranged from 3.00% to 5.72%. The water's physicochemical parameters and the type and content of the substrate were still suitable for mollusk life.

Abstract

Highlight Research The dose, duration of immersion, and time interval of immersion of the estradiol-17β affect the rate of cannibalism and increase the seed survival of Asian redtail catfish in low treatment in this research. Over optimum treatment increased the incidence of cannibalism at Asian redtail catfish and decrease growth performance. Treatment of estradiol-17β, give the ability of Asian redtail catfish to live on high density The treatment of estradiol-17β, has an effect on concentration plasma of body testosterone and cortisol   Abstract The cannibalistic behavior of Asian redtail catfish greatly hampers the supply of these fish seeds, invoking the need to be controlled. Estradiol is one of the hormones that has been known to reduce cannibalistic behavior on fish. This study aimed to evaluate the effect of estradiol-17β immersion on the incidence of cannibalism in the rearing of post larvae of Asian redtail catfish. Post larvae was treated with a combination of doses of estradiol hormone 0, 1, and 2 ppm and immersion time of two and four hours with immersion intervals of three and six days with a completely randomized design. Each treatment had a fish density of 10 fish L-1, with mean size individual length of 6.73 ± 0.73 mm (three days of age after hatched), with four replications. Fish were fed with tubifex up until satiation point and reared for 30 days. The results showed that the administration of the estradiol-17β through immersion with a dose of 1 ppm for two hours and interval of six days was able to reduce the level of cannibalism and increase the survivability. A further increase in dose, immersion time, and interval had the opposite effect. Estradiol-17β immersion with certain dose, duration, and interval affected the rate of cannibalism, growth rate, and survival. Estradiol-17β immersion at a dose of 1 ppm for two hours and six days interval was the best to reduce the level of cannibalism and normal mortality in post larvae of Asian redtail catfish.

Abstract

Highlight Research Paniculata leaf crude extract has antibacterial compounds Paniculata leaf crude extract can inhibit the growth of E. tarda bacteria Gouramy liver infected by tarda bacteria undergoes degeneration, congestion, and necrosis Treatment using paniculata leaf extract can improve Gouramy liver damage   Abstract Edwardsiellosis caused by bacterium E. tarda is a serious challenge faced by Gourami farmers. This study aimed to determine the antibacterial activity of A. paniculata leaf crude extract on the growth of E. tarda bacteria and its effect on the histopathology of gourami liver which was carried out in two stages. In the first stage, the active compound was identified in the leaves of A. paniculata followed by the Minimum Inhibitory Concentration (MIC) test at five different doses and two controls. In-silico test was conducted to determine the antibacterial activity of crude extract of A. paniculata leaf. In the second stage, the Lethal Dosage (LD50) and Toxicity (LC50) tests were carried out. Histopathological test of gouramy liver was carried out by taking the liver of fish that had been exposed to E. tarda bacteria. The active compounds contained in the crude extract of A. paniculata leaf are flavonoids, alkaloids, tannins, triterpenoids, and saponins. The Lethal Dosage (LD50) was 106 CFU/ml, and a toxicity test showed a dose of 250 mg/L caused the most death compared to other treatments. Histopathological test of gouramy liver showed that crude extract of A. paniculata leaf could improve liver function optimally at a dose of 300 (mg/L). The results of this study indicate that crude extract of A. paniculata leaf can affect the histology profile of gouramy liver and can cause toxicity if used inappropriately.

Abstract

Highlight Research The effect of immersion duration of shrimp to the immunostimulant from crude protein Zoothamnium penaei was determined. 20-minute immersion duration in crude protein from Zoothamnium penaei was found to increase the phagocytosis activities, phenoloxidase, and improve hepatopancreases of the shrimp. There is increase in phagocytosis activities, phenoloxidase and improved hepatopancreases cell within a three-week maintenance of shrimp with immersion after each seven days. There is interaction between immersion duration and maintenance time of shrimp into the crude protein from Zoothamnium penaei. Abstract Enterocytozoon hepatopenaei (EHP) is a spore-forming microsporidia intracellular parasite, which slough off the cells of the hepatopancreases of the shrimp. This study was intended to determine the effect of immersion duration and maintenance time to stimulate the immune system of shrimps by using a crude protein from Zoothamnium penaei to protect against EHP infections. The study used a completely randomized design where shrimps were divided into four groups each having five replicates. Groups P1, P2, P3 were immersed in immunostimulant for 10, 15, and 20 minutes respectively, except negative control. The phenoloxidase, phagocytosis activities, histopathology study were determined. Also, the molecular diagnosis of EHP was measured to confirm EHP infection in the shrimp samplesThe phenoloxidase activity significantly increased after immersion for 20 minutes (P3) from 0.64-, 0.72-, and 0.78-units min-1 mil -1 of protein on the first week, second week and third week, respectively. The phagocytosis activities of the sample immersed for 20 minutes were significantly increased to 68% on the second week. The sample also showed improved hepatopancreases epithelial cells with only 26% necrotic cell, less EHP spore and vacuolation. There was an interaction between immersion duration and maintenance time of the L. vannamei immersed in crude protein from Zoothamnium penaei. Twenty minutes immersion were significantly found to stimulate the immune system of the shrimp against EHP. The present work revealed that, the application of crude protein from Z. penaei is effective against EHP in shrimp culture.

Abstract

Highlight Research Snakehead fish head possess high protein content and potential to be used as materials for protein hydrolysate Snakehead fish head protein hydrolysis optimum condition were determined Snakehead fish head hydrolysate protein antioxidant activity were analyzed Snakehead fish head is potential to be used as materials for fish protein hydrolysate   Abstract There is concern regarding the use of synthetic antioxidants which spurred the yearly increase of natural antioxidants to substitute synthetic ones. Fish protein hydrolysate (FPH), which has been reported to have potent antioxidant properties, could be utilized to solve this problem. This study aimed to utilize the by-product of snakehead fish (head) and determine the optimum hydrolysis conditions to obtain FPH with antioxidant activity. Two parameters were tested during the hydrolysis process: enzyme concentration (papain enzyme) and hydrolysis time. The optimum condition was evaluated by measuring dissolved protein, hydrolysis degree (DH), and antioxidant activity, including DPPH, ABTS, and FRAP. The optimal hydrolysis conditions were 5% enzyme concentration and 6 h of hydrolysis time at 55°C and pH 7.0. The DPPH, ABTS, and FRAP antioxidant activities were 50.70%, 66.67%, and 1.35 M Tr/mg, respectively. Based on the antioxidant activity, Snakehead fish head has the potential as a source of natural antioxidants.
