Abstract

Guppy fish (Poecilia reticulata) is a type of ornamental fish that is in great demand, because of its small size and beautiful color. The color of ornamental fish will generally fade, due to a lack of carotenoids in their feed. The purpose of this study was to determine the effect of giving Tubifex sp. in commercial feed to increase the color intensity of guppy fish and the best dose of Tubifex sp. The test fish used were male guppy fish strain HB Red. This study used a completely randomized design (CRD) method with five treatments and three replications, that is commercial feed with the addition of Tubifex sp. with doses of 0% (P1), 2% (P2), 4% (P3), 6% (P4), and 8% (P5). Parameters observed were color intensity (chroma value), survival, and water quality. Addition of Tubifex sp. in commercial feed gave the effect with the highest yield on P5 at a dose of 8%, with an increase in color intensity (chroma value) of 4,21±0,25d. At P1 it gave an increase of 1,19±0,02a, P2 was 1,34±0,04a, P3 was 1,81±0,21b, and P4 was 2,88±0,18c. So, the best treatment is P5 (8%). Survival showed the results were not significantly different, that is 100%. Water quality is included in the tolerance limit of fish with the results of temperature 26,6 – 27,4°C, pH 7,4 – 7,9, and DO 6,2 – 7,7 mg/L.

Abstract

Amylolytic bacteria play an important role in the ecosystem, especially as probiotic and bioremediation agents in cultivation, as examples can be found in Mina Padi culture. The purpose of this study was to determine the amylolytic bacteria in the waters of the Mina Padi pond. Bacterial isolation began with bacterial sampling, inoculation and isolation of bacteria, calculation of the total abundance of bacteria, observation of bacterial morphology and bacterial purification, and isolation of amylolytic bacteria. The results of the isolation of amylolytic bacteria obtained 3 bacterial isolates capable of producing amylolytic enzymes, namely BA5, BA6, and BA7. The highest index of amylolytic activity was obtained by isolates of BA6 with a medium category of 2.3 cm, and the lowest index was obtained by BA5 with a weak category of 0.3 cm. The average bacterial abundance from each dilution was 2.5 x 103 CFU/mL.

Abstract

Microalgae, micro-sized plant organisms, play a crucial role in aquatic ecosystems. While many microalgae inhabit substrates or the bottom of water bodies, several types are planktonic. This study aimed to identify the types and abundance of microalgae in both sediment and water column habitats, as well as to analyse the environmental factors influencing their abundance. The research encompasses observations of water quality factors, microalgae abundance, relative abundance, diversity index, evenness index, and dominance index. Statistical analyses were using non-metric multidimensional scaling (NMDS) and Canonical Correspondence Analysis (CCA). The study was conducted in May-June 2022, with bi-weekly sampling at three points within each location for two months. Microalgae identified in the coastal area of Probolinggo belong to the Bacillariophyceae, Cyanophyceae, and Chlorophyceae classes. The highest microalgae abundance in sediment habitat was 58,472 ind/cm2, while in the water column was 4,118 ind/l. Diversity, evenness, and dominance indices in both sediment and water column habitats ranged from 1.93 to 2.61, 0.88 to 0.98, and 0.09 to 0.10, respectively. NMDS and CCA analyses indicate a graphical representation of the Bacillariophyceae class, demonstrating its prevalence across all sites.

Abstract

Salicornia europae is a marine plant that grows   in coastal areas and tides. In Sumbawa, this plant lives in the former area of ponds and usually called as lamota.  S. europae contains beneficial ingredients such as iodine, minerals, vitamins, antioxidants, unsaturated fatty acids, and sugars.  Marine plant innovations in S.  Europae, which is rich in iodine into processed yogurt, has not been well explored.  This study aimed to develop the processing of lamota into functional yogurt drink. Complete Randomized Design (CRD) was used in this experiment with a single factor of 6 levels of lamota concentration. Iodine content, ash content, pH and scoring test were carried out to find out the best quality of the lamota yogurt. The results showed that the iodine content of the product was 29.01 mcg / g dry weight and ash content was 10.59%. The pH showed that the addition of lamota minimally affected the pH of the yoghurt. In the organoleptic test found that 25% addition of lamota extract was the most preferrable concentration compared to 5, 10, 15, and 20% based on the color, taste, texture, aroma. Panelist describe the 25% lamota addition has greenish color, a little bit salty, watery texture, and green aroma. Based on the iodine content and the best consumers acceptance the yogurt with 25% addition of lamota could be categorized as a rich in iodine drink and a promising product to improve the functional characteristics of yogurt as well develop a value added local marine commodity with unique flavor.

Abstract

The snubnose pompano (Trachinotus blochii), which is an introduced fish, is currently in increasing demand, both for the domestic market (Jakarta and other big cities) and international markets such as Singapore, Taiwan, Hong Kong, and China. The snubnose pompano can be cultivated in ponds because it is tolerant to changes in salinity (5-40 ppt). In this study, the use of lights installed in cages used to maintain the snubnose pompano nursery will be responded to natural food that is positively phototactic (zooplankton, shrimp, and small fish species) which will gather as feed at night. So, it is hoped that the use of these organisms as an alternative feed source can increase feed efficiency. The urgency of this research is to determine efforts to save on the use of artificial feed and to suppress parasite attacks. A t-test was carried out to compare the averages of two different samples, on the growth rate and health of snubnose pompano fish. Research using lights resulted in optimum growth of snubnose pompano with 100% survival rate, feed conversion ratio (FCR) value of 0.9 and produced snubnose pompano size 80–100 g/head within two months as well as healthy fish seeds. With indicators of parasitic attack that are lower than the treatment without light with a prevalence value of 25% (with lights); range of 25%-75% (without lights) and intensity 6-8 (with lights); range 11-35.67 (without light). The snubnose pompano seeds are always actively moving when the light is on, the use of the light can effectively catch organisms such as small shrimp or small crustaceans so that the snubnose pompano seeds can be used to be digested as an alternative food (as observed in the stomach contents and intestines of the snubnose pompano). The light also indicates that parasitic attacks on the snubnose pompano are less common.

Abstract

Spiny lobster (Panulirus homarus) is a fishery commodity with high economic value. The classic problem that has not been resolved so far is the low survival rate of around 20-30% and an average growth rate of 180-230 grams. This can be influenced by nutritional factors, environment, stress and pathogen infection. This study aimed to identify pathogenic bacteria found in wild caught lobsters (Labangka) and cultivated lobsters (Bungin Island). The stages of this research began with taking samples in the field, followed by isolation and purification of bacteria (tail organs, gills, and hepatopancreas), morphological characteristics, and physiological tests of bacterial isolates. From the results of the study, it was found that the isolates grown on TSA media, showed a higher diversity of bacteria in natural lobsters compared to cultivated lobsters, this is what makes natural lobsters have a high survival rate because the diversity of microflora forms a symbiotic mutualism. Meanwhile, if we look at the diversity of pathogenic bacteria (Vibrio spp.), namely isolates grown on TCBS media, it shows that cultivated lobsters have more diverse pathogenic bacteria, namely three types of Vibrio (V. alginilyticus, V. Harvey and V. Parahemolyticus) are indicated, only natural lobsters identified V. alginilyticus.

Abstract

Applying biofloc technology in the intensive and extensive culture of Clarias gariepinus can improve water quality and be used to feed fish. Aeration systems were a critical unit supporting biofloc and water quality. This study's objective was assessment to various types of diffusers on the growth and water quality in a C. gariepinus culture. Two types of diffusers unit were prepared for the experiment, there are air tube diffuser (AT) and air stone diffuser (AS). Growth parameters, water quality, and volume of biofloc were observed within 30 days. The survival rate, weight gain, average body weight, and specific growth rate of C. gariepinus were higher in the tanks that used air tubes (98%, 485.29 %, 7.52 g, 5.89%) than in the tanks that used air stones (92 %, 385.94 %, 5.98 g, 5.23%). The volume of biofloc range from 5.40-18.80 ml/L in AT tanks and 4.60-14.00 ml/L in AS tanks. There is no significant difference (p > 0.05) in water quality parameters and FCR value. However, using the air tube diffuser showed better results with the growth performance, survival rate, and formation of biofloc.

Abstract

Marennine is a blue-green pigment produced by diatoms of the Haslea genus, one of which is Haslea ostrearia. This marennine pigment is water-soluble and confirmed to contain polyphenols and glycosides. There are two forms of marennine pigment: the intracellular form of marennine (IMn) and the extracellular form of marennine (EMn). Marennine pigments exhibit various biological activities such as antibacterial, antiviral, antioxidant, allelopathic, and inhibiting the growth of other diatoms. With this biological activity, marennine can be used in various fields, one of which is aquaculture.This research aims to determine the level of toxicity and analyze the effect of exposure to the extracellular marennine produced by H. ostrearia on the juvenile blood clam Tegillarca granosa. By using the toxicity test method, Blue water which is supernatant of H. ostrearia (BW) was tested on juvenile of commercially important bivalve species, the blood clams Tegillarca granosa, with three treatments, namely control (0 mg/L), treatment A (0.25 mg/L) and treatment B (0.5 mg/L of BW). The observation parameters of this study were LC50-72 h with one-way ANOVA analysis. The results showed that the BW produced by H. ostrearia increased the survival of juvenile blood clams T. granosa up to 27.7% in treatment B (0.5 mg/L) compared to control within 72 h. The one-way ANOVA analysis revealed that the control and treatment B (0.5 mg/L) were significantly different. This study shows that there is potential to develop the use of marennine in shellfish aquaculture.

Abstract

This study was conducted to determine the effect of vitamin C supplementation on the survival rate and histopathological changes of gills and kidneys of tilapia infected by Aeromonas hydrophila. Three doses of vitamin C were tested (150; 300; and 450 mg/kg) with two control groups. Tilapia with uniform size (average weight of 14 grams) as the criteria for inclusion were randomly distributed in five ponds with 15 tilapia fish per ponds. Tilapia was fed with hands until full for two weeks. Tilapia was then infected with A. hydrophila to find out the survival rate and histopathological changes of gills and kidneys at the end of the experimental period or 7 days after infection. The supplementation of 150 mg/kg vitamin C in feed increased the survival rate (%) in Tilapia by 86.67% or higher than other treatment and control groups. The damage to gills in terms of lamella separation was found in all treatment groups, as well as kidneys. The results found that the supplementation of 150 mg/kg vitamin C in feed increased survival rate but did not give effective protection on gills and kidneys.
