Ecophenotypic Variation of Midas Cichlid, Amphilophus citrinellus (Gunther, 1864), in Lake Batur, Bali, Indonesia

Brazilian Journal of Biology (2024)

Rudhy Gustiano Gadis Sri Haryani Siti Aisyah Firman M. Nur Gde Raka Angga Kartika

Abstract Cichlid fishes exhibit rapid adaptive radiations with significant diversification rates in response to ecological variability, i.e., ecological opportunity or geographical isolation. The discovery of a Midas cichlid species in Lake Batur, Indonesia's largest volcanic lake, first reported in 2013, could represent such adaptations. Midas cichlids can now be found in a range of habitats in Lake Batur and dominate the lake's fish population by up to 60%. This study aimed to identify the interaction between habitat, water quality, and Midas cichlid in Lake Batur, facilitating morphometric variances in the fish populations. The fish were captured at five locations in Lake Batur using fishing rods, community nets with mesh sizes of 2–3 inches, experimental gillnets with mesh sizes of 1 inch, and fish scoops in floating net cages during August and November 2022. There were 46 fish samples caught from the five stations, all photographed using a digital camera and later measured using the ZEN 2012 software. The fish measurement employed a truss morphometric method using 21 distinct morphometric body features. Canonical analysis was used to determine the distribution of characteristics, while discriminant analysis was used to examine the closeness of association. The measured water quality parameters included pH, DO, temperature, conductivity, and TDS for in-situ and TSS, TP, TN, and chlorophyll A for ex-situ. The findings revealed morphometric changes among Midas cichlid species in Lake Batur caused by habitat and water quality differences. The distinction can be detected in the anterior and posterior bodies (C1, B1, C3, C6, C5, B3 and B4). Temperature and aquatic plants, Azolla pinnata, may detect the station and shape of fish in Lake Batur. Body shape cannot be identified by chlorophyll A, TN, DO, and TDS. Future genetic research could answer why fish groups with varied body types coexist in the same location.

Abstract Molluscicide of fentin acetate (C 20 H 18 O 2 Sn) is commonly used at the present due to effective in terms to control of molluscs in the rice field. The aims of this experiment is to determine toxicity effect of fentin acetate on growth, productivity, and blood glucose on the common carp, Cyprinus carpio cultured at rice field water. A 12 of rice field plots with size of 25m 2 each were used. The stocking density of common carp was 25 fish/m 2 for each rice plot. The culture period of the common carp was 21 days. The different fentin acetate concentration as treatments were as followed M0) without molluscicide; M1) 0.375 g/L of molluscicide; M2) 0.75 g/L of molluscicide); and M3) 1.5 g/L of molluscicide. Statistical analysis using one-way ANOVA with three replicates for each treatment was performed. The result showed that the treatment of molluscicide at 0.75 g/L was significantly different to the others on survival rate and productivity (p<0.05). Application of 0.75 g/L of molluscicide showed a positive correlation on blood glucose value.

Utility of almond leaf (Terminalia cattapa) for improving growth and color quality of neon tetra fish (Paracheirodon innesi)

IOP Conference Series Earth and Environmental Science (2020)

Idil Ardi Mochammad Zamroni Eri Setiadi

Abstract Ornamental fish farming is easy to stress, which results in fading colors and patterns of the body. The effort to maintain the color and pattern of the fish’s body are using Almond leaf. This study aims to obtain the optimum concentration of Almond leaf in the maintenance of neon tetra fish, which is expected to improve the color quality and growth of fish. Neon tetra fish seeds measuring 1 - 2 cm were maintained in an aquarium sizing 25 cm x 40 cm x 28 cm with a stocking density of 4 tails liter −1 . The completely randomized design (CRD) was applied with four treatments and three replications. The different of Almond concentrations as a treatment i.e. 0 ppm, 250 ppm, 500 ppm, and 750 ppm. Parameters measured such as survival (SR), growth (absolute length and weight), color quality (lightness, chroma, hue a, and b) and glucose levels. Water quality measured such as DO, temperature, pH, conductivity, TDS, ammonia and nitrite. The results showed that Almond leaf affected the growth of absolute length and absolute weight. Almond leaf with a concentration of 500 ppm could improve color quality, especially for green-red colors.

PRODUCTION PERFORMANCE AND BLOOD PROFILE OF CLIMBING PERCH Anabas testudineus Bloch CULTURED IN PEAT POND WITH DIFFERENT STOCKING DENSITIES

Indonesian Aquaculture Journal (2019)

Ani Widiyati Adang Saputra Eri Setiadi

Climbing perch is one of economically-valued local fish in Indonesia, particularly in Borneo, Sumatra, and Java Islands. The fish has the potential to be developed as freshwater aquaculture species. The purpose of this experiment was to evaluate the production performance and blood profile of climbing perch cultured in peat pond with different stocking densities. The research was conducted in Kereng Bangkiray Village, Sebangau District, Palangkaraya City, Central of Borneo. Nine fish ponds sized 5.0 m x 5.0 m x 1.5 m were used. Nets with a mesh size of 1 cm measuring 2.0 m x 1.5 m x 1.0 m was installed in each fish pond for the experiment. The treatment consisted of different stocking densities, namely 15 fish/m2, 30 fish/m2, and 45 fish/m2. Fish with the body weight of 20 ± 1.25 g were used. Fish were cultured for four months. An artificial diet containing 30% protein was given with a feeding rate of 5%. The experiment was designed in a complete randomized design. The result showed that the production performances (i.e. survival, specific growth rate, absolute weight, and biomass) were significantly higher at the densities of 15 and 30 fish/m2 than that of 45 fish/m2 (P<0.05). Blood profile such as glucose, erythrocyte, leucocyte, and hemoglobin were higher at the density of 45 fish/m2 except for hematocrit which was higher at the densities of 30 and 15 fish/m2. Water quality parameters such as dissolved oxygen, nitrite, nitrate, and ammonia at the densities of 15 and 30 fish/m2 showed better values than that of 45 fish/m2 stocking density. To optimize the productivity and maintain the optimum water quality condition, the optimal stocking density for climbing perch culture is suggested at 30 fish/m2.

PEMBERIAN MINYAK CUMI PADA PERMUKAAN AIR TERHADAP ABNORMALITAS DALAM PEMELIHARAAN LARVA IKAN KERAPU BEBEK (Cromileptes altivelis)

Jurnal Riset Akuakultur (2016)

Eri Setiadi

Pembenihan ikan kerapu bebek (Cromileptes altivelis) di Indonesia telah berhasil dengan baik, namun masih dijumpai tingginya abnormalitas. Penelitian abnormalitas pada stadia perkembangan larva dari yolk sac sampai flexion melalui pewarnaan tulang telah dilakukan. Tujuan penelitian adalah untuk mengetahui pengaruh minyak cumi pada permukaan air terhadap abnormalitas, saat abnormal mulai muncul dan bagian tulang yang rentan terhadap abnormal serta sintasannya. Hasil penelitian dari stadia yolk sac sampai flexion menunjukkan bahwa persentase abnormalitas pada pemeliharaan dengan minyak cumi pada permukaan air lebih rendah (P<0,001) dibandingkan dengan tidak menggunakan minyak cumi pada permukaan air. Abnormal mulai terlihat pada stadia preflexion dan flexion. Tipe-tipe abnormal yang dijumpai adalah lordosis, skoliosis, khiposis, fusi, reduksi, percabangan, dan penambahan. Bagian tulang yang rentan terhadap abnormal ditemukan pada vertebrae bagian tengah (15,21%) dan hypurals (8,50%) pada pemeliharaan dengan minyak cumi, sedangkan tanpa menggunakan minyak cumi dijumpai pada dorsal proximal radials (32,50%) dan vertebrae bagian posterior (31,88%). Sintasan sebesar 7,04% (P<0,0001) dijumpai pada pemeliharaan dengan minyak cumi pada permukaan air, sedangkan tanpa minyak cumi pada permukaan air hanya 2,48%. Penggunaan minyak cumi pada permukaan air dapat menurunkan abnormalitas dan meningkatkan sintasan.The mass seedling production of humpback grouper to (Cromileptes altivelis) has largely been successful in Indonesia. However, the high rate of abnormality of seed produced is the main problem. The rate of abnormality from yolk sac to flexion stages was examined. The purpose of the study was to examine the influence of squid oil at the water surface to the abnormality and determine which part of skeleton was vulnerable to deformation using clearing and staining methods. The result had indicated that larvae reared using squid oil at the water surface showed significantly lower (P<0,001) compared to that without squid oil at the water surface in abnormality. The deformation occurred at preflexion stage in both of squid oil or without squid oil at the water surface was detected. The types of deformities encountered during larval rearing period were as follows: scoliosis, lordosis, khyposis, fusion, shortening, branching, and supernumerary elements. Based on nine of bone elements indicated that larvae reared using squid oil at the water surface showed the rate of abnormality in the middle of vertebrae (15,21%) and hypurals (8,50%) while that without squid oil at the water surface showed the rate of abnormality of the dorsal proximal radials (32,50%) and the vertebrae at the posterior region (31,88%). The survival of larvae reared using squid oil at the water surface was higher (7,04%) (P<0,0001) than without squid oil (2,48%). Squid oil addition at the water surface could reduce the abnormality and increase in the survival rate.
