Sensory-mediated feeding behaviour in the larvae of marble goby (Oxyeleotris marmorata)

This study was conducted to determine the senses that facilitate prey detection in the marble goby (Oxyeleotris marmorata) larvae. The ingestion ratios of live (generate chemical and mechanical stimuli) or frozen Artemia nauplii (generate chemical but no mechanical stimuli) by the intact or free neuromast (mechanoreceptor)-ablated O. marmorata larvae (11 mg/L streptomycin treatment before feeding) under the light or dark (fish vision was obstructed) condition were examined. Vision, mechano-, and chemoreceptions were all found to be essential in prey detection of the O. marmorata larvae. Prey movement has a significant influence as a visual stimuli on the O. marmorata larval feeding as the Artemia nauplii ingestion ratio was approximately 40% higher with significant (p = 0.001, d = 3.0), when the intact larvae were fed with the live (78.1 ± 1.5%), rather than the frozen (40.9 ± 2.8%) Artemia nauplii, under the light condition. This result was assured when no significant difference (p = 0.572, d = 0.2) was found between the ingestion ratios of frozen Artemia nauplii by the intact O. marmorata larvae under light and dark conditions. These findings demonstrate that prey detection in the O. marmorata larvae was facilitated by multi-modal senses, allowing O. marmorata larvae to survive in their natural habitats.

Relationship Between Length and Weight and Habitat Conditions of Several Fish Species in Tondano Lake, Minahasa, North Sulawesi

The snake-head gudgeon or payangka fish (Ophieleotris aporos), tilapia fish or mujair (Oreochromis mossambicus), and marble goby or betutu fish (Oxyeleotris marmorata) are economically important fish in Lake Tondano. However, numerous community activities can disrupt aquatic biodiversity, declining Lake Tondano environmental conditions, and other factors. This study aimed to determine the relationship between length and weight and the habitat conditions of Ophieleotris aporos, Oreochromis mossambicus, and Oxyeleotris marmorata. The method used in this study was purposive sampling with research stations located at Remboken (station 1), Kakas (station 2), and Tondano Estuary (station 3). Sampling was carried out 5 times in every 10 days. The weight and length of the fishes caught in Lake Tondano were 2-60 g and 1-8 cm (Ophieleotris aporos); 9-180 g and 6-25.5 cm (Oreochromis mossambicus); and 16-30 g and 2.6-26.5 cm (Oxyeletotris marmorata), all of them have an allometric growth pattern. Oreochromis mossambicus is the most commonly caught fish in all research stations. The research station with the best level of water fertility is Remboken Station. The habitat characteristic of Lake Tondano was 25-290C of water temperature; brightness of 1.34-2.66 m; depth of 4.23-11.8 m; pH of 6.7-7.8; and dissolved oxygen of 2.27-6.31 mg/L, which still supports the well-being of the fish.

Lactiplantibacillus plantarum fermented broth improved survival of marble goby (Oxyeleotris marmoratus) after skin abrasion by regulating skin mucus microbiota

Skin abrasion makes fish more susceptible to pathogen infections, which may cause a substantial increase in fish mortality. Hence, a 22-day trial was carried out to investigate the effect of Lactiplantibacillus plantarum fermented broth on the survival and microbiome regulation of marble goby (Oxyeleotris marmoratus) after skin abrasion. 135 fish (initial average weight, 3.39 ± 1.36 g) were divided into 9 tanks with triplicate treatment groups: control group (healthy fish), abraded group (skin abraded fish) and abraded &L. plantarum-treated group (skin abraded fish and 100 ppm L. plantarum fermented broth adding). The results showed that skin abrasion caused a 28.89% decrease in survival percentage of fish compared to the control group, whereas L. plantarum fermented broth significantly increased survival percentage by 44.45% when compared to the abraded group. Furthermore, skin abrasion reduced the diversity of bacterial and fungal communities in skin mucus and the abundance of Bacteroidetes phylum, Firmicutes phylum and Hydrogenophaga flava species, while increased the abundance of Aeromonas veronii and Cetobacterium somerae species. Nevertheless, L. plantarum treatment resulted in opposite results in fish, and it also increased the abundance of Lactobacillaceae family and potential bacterial and fungal probiotic species in gill and skin mucus. In conclusion, L. plantarum fermented broth may improve survival percentage of marble goby after abrasion by modulating the microbiota composition of fish skin mucus.

Growth Performance and Nutritional Condition of Marble Goby (Oxyeleotris marmoratus) Larvae Fed under Different Onsets of First Feeding

The marble goby (Oxyeleotris marmoratus) is a valuable food fish, but its aquaculture production is often hampered by poor growth performance associated with starvation at an early stage. The objective of this study was to investigate the effects of delayed initial feeding on the growth performance and nutritional condition of the marble goby. Six different first feeding times were examined: 0, 12, 24, 36, 48, and 60 hours after the first feeding (HAFF), and their impacts on growth performances were evaluated based on larval final total length (mm) and survival (%), while nutritional condition was evaluated based on body morphometric changes, gut epithelium height (μm), and gut condition. The experiment was conducted for 15 days. All parameters were measured after larvae were collected at different sampling times, except survival and growth, which were measured at the end of the experiment. The results showed that the onset of the first feeding was 36 h after hatching (hAh) and that a short delay in the first feeding by 12, 24, 36, 48, and 60 HAFF significantly reduced the growth performance of the larvae and severely affected the larval nutrition condition with noticeable shrinkage in body morphometry and gut epithelium height. This study concluded that the onset of first feeding in marble goby occurs at 36 hAH and that first feeding beyond 36 hAH significantly worsens the nutritional condition and growth performance of the larvae.

Diversity and Abundance of Fish in The Bone Canal

This study aims to describe the species diversity and abundance of fish in the Gorontalo Bone Canal. This research was conducted in the Bone Canal, Bone Bolango district, Gorontalo province with a survey method. Fish identification was carried out at the Zoology Laboratory of the Biology Department, State University of Gorontalo. The sampling technique was random sampling using nets installed at four observation stations for 24 hours. Station I is the northern part of the canal (upstream), station II is in the middle of the canal, station III is in the southern part of the canal (downstream) and station IV is located at the mouth of the Bone canal. Measurements of the physical and chemical parameters of water were carried out at each station. The fish caught were identified by referring to the book: “Identification of Freshwater Fish in Western Indonesia and Sulawesi” by: Kottelat at al, (1993). Research results and conclusions: 185 individual fish were found consisting of 3 orders, 5 families and 7 species, including: Cyprinus carpio and Barbonimus goionotus (Cypriniformes: Cyprinidae), Hypostamus sp. (Siluriformes: Loriicaridae), Oreocrhomis mosambicus and Oreochromis niloticus (Perciformes: Cichlidae), Oxyeleotris marmorata (Perciformes: Eleotrididae), and Anabas testudineus (Perciformes:Anabantidae). The highest diversity index is at station IV with H’= 1.96 and the lowest is at station I with H’= 1.50. This shows that the level of diversity of fish species in the Bone canal is moderate, the productivity is sufficient, the ecosystem condition is quite balanced and the ecological pressure is moderate. Hypostamus sp. has the highest level of abundance in all stations with an average of K = 30.9%. The lowest abundance was Cyprinus carpio with an average of all stations K= 3.3%, indicating that the abundance in Bone canal was relatively moderate.

Growth of Betutu fish (Oxyeleotris marmorata BLEEKER, 1852) in Tondano Lake, North Sulawesi

The introduction of non-natural species to new environments is one of the main factors reducing and extinction of local diversity. The purpose of this study was to analyze the growth of betutu fish (Oxyeleotris marmorata Bleeker, 1852) in Tondano Lake. This research was conducted using a purposive sampling method, fish samples were obtained from the catch in a time series every month, sampling using gill nets at five stations and calculating fish growth based on the frequency of total length measurements. Data were analyzed using FiSAT II software. The results showed that the growth of the betutu fish was relatively fast in terms of the growth coefficient (K) value obtained of 1,700 per year so that the breeding of this fish was increasingly dominant compared to the growth of local fish.

Transportation and Acclimation Optimisation of Wild Marble Goby (Oxyeleotris marmorata Bleeker, 1852)

The Marble goby (Oxyeleotris marmorata Bleeker) is usually found in freshwater bodies. Due to its high commercial value and demand, it is farmed in cages and pond systems. Marble goby fish are preferred to be freshly killed and processed upon request in Asian restaurants. Currently, there are some challenges faced by fishermen who wish to transport live fish to restaurants or markets due to the traditional method of using water tanks as carriers. These water tanks are usually very heavy and bulky, increasing transportation costs. Furthermore, coping with the survivability of fish post-transportation has proven to be a challenge. This study was aimed at investigating the semi-dry method for fish transport and acclimatization of fish after transport in different tank sizes. In the semi-dry, where fish were covered using a towel transportation method where the survival rate at ~92%. For the acclimation experimental group, stream water was found to be the most appropriate type of water for rearing the marble goby fish, which demonstrated a conspicuous survivability rate of ~83%. whereas, for adaptation, marble goby fish from the wild had a faster adaptation rate in smaller spaces like aquariums as compared to large ‘stock tanks.’ To the best of our knowledge, this is the first study that will provide a better understanding of the transportation method, acclimation conditions, and habitat that can lead to a reduction in the mortality rate during the marble goby transit processes.

These fish species come from Familia Siluridae, Cyprinidae, Cannidae, Eleotridae, Pangasiidae, Bagridae and Helostomatidae. The highest relative abundance (Kr) was the Salap beruntus (Barbonymus gornionotus). The most common type of fish found (Fi) was white Lais fish, 58.3% Fi and the least common were Toman (Channa micropelte), black Betutu (Oxyeleotris selheimi) and Red Betutu (Oxyeleotris marmorata).

Mapping the Distribution of Fish Caught in the Jatigede Reservoir, Indonesia

This research aims to map the structure of the fish community living in the floodplain of the Jatigede reservoir based on the catch. This research uses the field observation method, taking fish samples every 14 days and doing 6 times. The results of the survey show that the number of fish caught during the survey was 799 individuals, and the fish species identified at 6 stations of Jatigede Reservoir consisted of 9 families of 18 species. The fish species with the highest abundance was Parambassis siamensis at station 1. At stations 2, 3, 4, and 5, the fish with the highest abundance was Hampala macrolepidota and at station 6, the fish with the greatest abundance was Oxyeleotris marmorata. The distribution of native fish is more dominant than introduced fish with a comparison of 11 native fish species and 7 introduced fish species. The water quality at each station still meets the requirements of environmental quality standards according to Government Regulation (Indonesia) No. 22 of 2021 on Water Quality Standards and is suitable for fish life.

Optimal time of year and fishing methods for controlling exotic fishes in Longluan Lake, Taiwan

Aim: This study aimed to identify the optimal time and fishing methods for removing exotic fishes, including striped snakehead (Channa striata), marble goby (Oxyeleotris marmorata), tilapia (Oreochromis spp.), three-spot gourami (Trichopodus trichopterus), and predatory carp (Chanodichthys erythropterus), from Longluan Lake, which is located in Kenting National Park in Taiwan. Methodology: The selected fishing methods included lure fishing, longline fishing, and fyke netting. A total of 2,284 individuals were collected over 12 removal events in Longluan Lake from 2017 to 2019. Among the collected fish, 1,640 fish represented exotic species, and 644 fish represented native species. Results: Among the collected fish, 1,640 fish represented exotic species, and 644 fish represented native species. Based on the results of this study, we suggest that the optimal time for managing exotic fishes is from April to June, when is the period representing lower water levels in Longluan Lake. For removing specific exotic fish in Longluan Lake, employing lure fishing in natural habitat is effective for C. striata and Oreochromis spp., utilizing fyke netting in natural habitat is workable for T. trichopterus and C. erythropterus, and operating fyke netting in artificial habitat is useful for O. marmorata. Interpretation: The habitat preferences and sampling efficiency of gears vary among exotic fishes, however, a combination of applying lure fishing and fyke netting in both habitat types will achieve the greatest advantage for controlling exotic fishes in the Longluan Lake.

Optimization of enzymatic hydrolysis of boso fish (Oxyeleotris marmorata) protein based on the degree of hydrolysis and the physical properties of the resultant hydrolysates

Fish protein hydrolysates (FPHs) were produced from boso fish (Oxyeleotris marmorata) through enzymatic hydrolysis using papain as the hydrolysis agent. Papain concentration (0.2–0.4%), temperature (45–55°C), and time (4–12 hrs) were chosen as the independent factors while the degree of hydrolysis (DH), viscosity, and turbidity of the resultant FPHs were recorded as the responses. This study aimed to optimize the enzymatic hydrolysis of boso fish protein using the Box-Behnken Response Surface Methodology (RSM) design. The optimum condition for the boso fish protein hydrolysis based on the DH was predicted at 0.2% of papain concentration, 55°C, and 12 hrs, which would give a DH of 18.63% and an R2 of 90.90%. The FPHs prepared with moderate hydrolysis conditions (0.3% of papain concentration at 50°C for 8 hrs) were spray-dried with the yield ranging from 5.37% to 16.70% (w/w). The spray-dried FPH displayed a globular structure with a diameter of 1–7 μm as observed under the scanning electron microscope (SEM). The total colour difference of the dried FPH was 10.15 compared to the standard white tile. The particle size analysis in distilled water exhibited some distinct peaks which were distributed within 200–1,100 nm with an intensity of 18.1%. This study showed the potential of boso fish for FPH production by using the papain enzyme.

Introduced fish species and their characters in Lake Maninjau, West Sumatra

The diversity of indigenous fish species in Lake Maninjau has been declining with the rise of local people’s activities. One of the causes is the invasive species, which are initiated by introduced species. This study aims to discover the species, distribution, growth pattern, and condition factor including information of the environmental condition, supporting the existence and growth of introduced fish species in Lake Maninjau. Sampling was conducted at four locations in Lake Maninjau; Bayur, Linggai, Sigiran, and Galapung. Fishes were collected by experimental gillnet which vary in mesh size, 0.5; 0.75; 1; 1.5; 2; 3; and 4 inches. These nets were set about 12 hours from 8 pm to 8 am on the next day, once a month in May, July, August, September, and October 2017. Four introduced fish species were observed and examined; there were Cichlasoma trimaculatum (Three-spotted cichlid), Oreochromis niloticus (Tilapia), Pterygoplichtys pardalis (Armored Catfish), and Oxyeleotris marmorata (Marble Goby). O. marmorata and O. niloticus were recorded at all of the sampling locations. C. trimaculatum was recorded in Galapung and Sigiran, while P. pardalis only found in Bayur. These dominant fish species have growth patterns each; there are negative allometric (O. marmorata), isometric (C. trimaculatum), and positive allometric (O. niloticus). Moreover, these three fish species have an almost 1.00 condition factor; there were 0.988, 1.024, and 1.001, respectively. Results and discussion infer that introduced fish species in Lake Maninjau were distributed at several locations with good growth and condition.
