Abstract

Euchema cottoni or Kappaphycus alvarezii is one type of seaweeds that is widely cultivated in Indonesia. Water pollution caused by the accumulation of Pb heavy metals will affect the seaweed to grow and develop. This study is aimed to determine the tannin levels in K. alvarezii and the relationship of Pb heavy metal pollution level with tannin levels in K. alvarezii in different waters. This study used an observational experiment, and samples were taken from two different locations with 4 stations in each. From each sample in both locations, K. alvarezii was taken and was then measured for the tannin levels, water quality, and heavy metals (Pb) in water and in K. alvarezii. The results were analyzed at the Laboratory of PT. Sucofindo and the Laboratory of Testing Service Unit, Airlangga University Surabaya. The data were analyzed using a statistical test in the form of a t-test to determine the differences in samples in both waters, and a C-square test was used to determine the relationship between PB and tannin levels in K. alvarezii. The results showed that the level of Pb heavy metal pollution in the two waters did not show a significant difference due to water quality which was quite similar in both locations. Moreover, the tannin content in K. alvarezii in Bluto waters (0.053±0.004%) was higher than that in Talango waters (0.020±0.009%). Meanwhile, a t-test showed a significant difference in seaweed tannins in both waters. The relationship between Pb heavy metal pollution and tannins of seaweed in Bluto and Talango waters was that they did not affect each other, and tannin concentration was more influenced by chemical oxygen demand (COD), salinity of both waters, and the cultivation methods used.

Abstract

The pathogenic bacterial infection is one of the problems in the cultivation of vannamei shrimp (Litopenaeus vannamei), causing a high mortality rate of cultured shrimp. The use of antibiotics or chemicals with inappropriate concentrations can harm the aquatic environment, cause resistance, and endanger consumer health because the residues from the chemicals used will periodically accumulate in the body of shrimp. One way to control and prevent shrimp disease is to increase the shrimp immune system by using immunostimulants from seaweed. This study aims to analyze the immunostimulant activity of seaweed extract (Gracilaria sp. and Padina sp.) against vannamei shrimp (L. vannamei) infected with Vibrio harveyi by observing the nonspecific immune system based on its hematological features, namely by counting the number of hemocytes and phagocytic activity. The research was conducted at the Hatchery Unit, Brackish Water Cultivation Development Center (BPAP) Situbondo, East Java. Seaweed sample Gracilaria sp. and Padina sp. purchased from seaweed farmers in Jepara, Central Java. The result of this study shows that supplementation of Gracilaria sp. and Padina sp. at a dose of 10 g/kg of feed can increase the total number of hemocytes and phagocytosis activity of L. vannamei shrimp. The best treatment is Gracilaria sp.

Abstract

Snakehead fish Channa striata is a high commercial freshwater fish commodity. It has the potential as a pharmaceutical ingredient. Intensive snakehead fish cultivation starts to experience a problem, namely Motile Aeromonas Septicemia (MAS) caused by Aeromonas hydrophila. The purpose of this study is to evaluate the effect of the addition of commercial yeast in feed to improve snakehead fish immunity. This study was designed with a completely randomized design (CRD) with 5 treatments with 3 replications (reared in the net) and 6 treatments with 3 replications (reared in the aquarium). The treatments were K (feed without yeast), F5 (feed with the addition of 5 g/kg of cake yeast), R3 (feed with the addition of  3 g/kg of tempeh yeast, R5(feed with the addition of 5 g/kgof tempeh yeast), and R7 (feed with the addition of 7 g/kg of tempeh yeast). The results show that the survival rate after 30 days is 88.89- 92.22%. The best treatment after A. hydrophila infection was found in fish fed with 3 g/kg oftempehyeast with a survival rate of 56.67%, total erythrocytes of 4.07x 106 mm-3 cells, hemoglobin of 7.40 g% of total leukocytes 4.97x 104 mm-3 cells and phagocytic activity of 33.67. In conclusion, the addition of tempeh yeast at a dose of 3 g/kg could be used as an alternative to prevent the effect of A. hydrophila pathogen infection in snakehead fish.

Abstract

Udang merupakan salah satu komoditas unggulan nasional dan memiliki nilai ekonomi yang tinggi. Produksi udang budidaya di Indonesia tahun 2012-2017 mengalami kenaikan secara signifikan. Meski mengalami kenaikan, masih terdapat masalah yang harus diatasi, salah satunya adalah penyakit yang disebabkan oleh parasit Enterocytozoon Hepatopenaei (EHP). Infeksi EHP mengganggu sel tubulus hepatopankreas. Lesi yang disebabkan oleh EHP dapat menjadi tempat pertumbuhan koloni Vibrio sehingga meningkatkan kemungkinan munculnya penyakit lain. Penelitian ini bertujuan untuk mengetahui keanekaragaman Vibrio pada udang terinfeksi EHP yang dianalisis dengan Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC PCR). ERIC PCR dapat membedakan strain bakteri yang berkerabat dekat, prosedur kerja yang sederhana, cepat dan murah. Bakteri Vibrio diisolasi dari hepatopankreas, feses dan air udang terinfeksi EHP dan udang sehat (kontrol), dilanjutkan dengan ekstraksi DNA, ERIC PCR, elektroforesis dan konstruksi pohon filogenetik. Hasil penelitian menunjukkan bahwa jumlah bakteri Vibrio pada hepatopankreas, air dan feses udang terinfeksi EHP lebih tinggi dibandingkan dengan udang sehat. Udang terinfeksi EHP memiliki keanekaragaman Vibrio yang lebih rendah dari pada udang sehat. Hal ini menunjukkan adanya spesies Vibrio spesifik yang mendominasi pada udang terinfeksi EHP.

Abstract

The ornamental fish business is now an economic driver. The ocellaris clownfish (Amphiprion ocellaris Cuvier, 1830) is one of the leading commodities of marine ornamental fish that is in great demand, especially in foreign markets. One obstacle faced by farmers in determining the appropriate density for the ocellaris clownfish rearing stage. This study aimed to evaluate the effect of stocking density on production factors, which included survival rate, and growth rate of ocellaris clownfish. Three hundred fish were used as experimental fish with an average length of 23.00 ± 2.36 mm and a weight of 0.27 ± 0.02 gather study was conducted using 4 treatment tanks with a volume of 120 L with densities of 0.17, 0.37, 0.67, and 0.80 fish/L. Observations showed that the density of 0.37 fish per L (K2) gave the best results with a survival rate of 98.18%. For the SGR parameter, the highest value was 1.14% per day in the K1 treatment. This indicated that the stocking density has a relationship with the factor of production in rearing ocellaris clownfish in the recirculation system.

Abstract

Biofouling refers to the attachment of organisms to the surface of an object submerged in water. It is often undesirable due to its detrimental effects, meanwhile, one way of managing biofouling is via antifouling. This study aims to examine the potential of kenikir (Cosmos caudatus) and bandotan (Ageratum conyzoides) leaves extracts as an alternative to natural antifouling. The research was conducted using the exploration method where the extract of both plants was examined in field and laboratory scales. Moreover, the extracts were mixed with paint without antifouling and then tested on a field scale by painting on wooden blocks. Observations were made by counting the number of microfouling in form of bacterial colonies attached to the painted wood surface by scraping the surface of the wood submerged in freshwater for one week. The results showed that the number of bacterial colonies with kenikir leaves extract was less than the bandotan extract. Moreover, based on the phytochemical analysis results, both kenikir and bandotan extracts contain alkaloids, steroids, tannins and saponins, however, the alkaloid content in kenikir leaf extract was higher compared to bandotan leaves. In conclusion, kenikir leaves extract has greater potential as an alternative source of antifouling compared to bandotan because the former has more bioactive content, especially alkaloid compounds.

Abstract

Eyestalk ablation inflicted upon crustacean is generally performed in captivity to induce ovarian maturation. However, ablation is a hurtful action that may impose physiological stress and even affects survival. The immunologic repercussions of the ablation have not been well understood and thus this study aims to analyze the effect of ablation on immunologic variables through comparing the ablated Litopenaeus vannamei with those of unablated shrimps (control).  Unilateral left eyestalk ablation was inflicted on shrimp samples. Shrimp immune responses were observed based on the Total Haemocyte Count (THC), Differential Haemocyte Count (DHC) composing of hyaline cell (HC) counts and granular cell (GC) counts, glucose and uric acid levels, along with the weight gains of shrimps. Observed parametres were taken twice from 10 shrimps for each of the observed and control samples (i.e., on 6 h and 5 d elapsed time). The results show that the ablated shrimps group, after 6 h elapsed time, experienced significant decrease in THC (3.12 ± 0.75 x 106 cells ml-1), but recovered after 5 days (3.89 ± 0.96 x 106 cells ml-1) and were not significantly different from the control (5.16 ± 2.20 x 106 cells ml-1). Meanwhile, glucose level show significant decrease over 6 h and 5 d post ablation (108 and 93 mg dL-1, respectively) compared to the resulting responses from the control (35-36 mg dL-1). Differences in DHC for all cell types as well as uric acid in hemolymph were not significant between the observed and the control samples. Moreover, the ablated treatment did not affect the growth of vannamei after 5 d post ablation. The results revealed that changes occur on the physiological and immune parameters of shrimps due to the eye ablation treatment as shown by the decrease in the THC and glucose levels, especially within the early moments post treatment. However, at the end of the observation (5 d post ablation), shrimps exhibit signs of recovery from stress indicated by an increase in THC close to normal.

Abstract

Caulerpa is one of the seaweed that grows naturally in Indonesian waters such as those in Mandangin Island. This study aimed to identify Caulerpa sp. based on molecular analysis using certain genetic markers. This research is expected to provide information on the identification of macroalgae from Indonesia waters, especially Mandangin Island, Madura with the use of molecular analysis based on 18SrRNA primers. The two green seaweed samples from the Caulerpa genus in this study were successfully analyzed using 18SrRNA primers. The BLAST results of samples 1and 2 are related to Caulerpa taxifolia 18SrRNA, but in the phylogenetic tree result, Sample 1 was more closely related to Caulerpa sertularioides f. longipes. 18SrRNA primers have been used for molecular identification of green seaweed from Mandangin for the first time and this shows that barcode markers can be used for molecular identification of seaweed, specifically Caulerpa in the waters of Mandangin Island, Indonesia.
