“…This morphological variation can be induced by environmental factors, i.e., temperature, turbidity, and water currents (Mir et al, 2013;Yulianto et al, 2020), as well as habitat characteristics (Shuai et al, 2018;Webster et al, 2011). Such morphological changes due to environmental pressure can be accelerated by the fish's inherent phenotypic plasticity (Nur et al, 2022;West-Eberhard, 2008) and geographic isolation (Worsham et al, 2017). In most cases, a sufficient degree of isolation can even result in both morphological and genetic diversity across fish populations within a species (Turan, 2004).…”

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.

“…Fighting fish belong to the Betta genus, there are at least 69 species of Betta fish in the world, of which 48 species are found in Indonesian waters, and 37 of them are endemic to the Kalimantan and Sumatra Islands [1], where four species are found in Aceh waters, namely; B. rubra, B. splendens, B. imbellis and B. dennisyongi [2]. B. dennisyongi lives in marshy areas with blackish murky water with slow currents.…”

Fighting fish Betta dennisyongi is a popular ornamental freshwater fish in Indonesia. Male fighting fish are preferred because the colour pattern and shape of the fins are more attractive so they are more expensive. This study aims to determine the optimum temperature of rearing media water on the male sex ratio and survival rate of fighting fish larvae. A completely randomized design method with three replications was used in this study. The tested rearing temperature water was: 26°C, 28°C, 30°C, and 32°C. Fish were kept for 40 days. The results of the ANOVA test showed that larval rearing temperature affected significantly the ratio of male and female fish larvae survival (P<0.05). The highest percentage of the male sex was found at a temperature of 32 °C (93.33%), this value was significantly different from other temperature treatments. Meanwhile, the highest larval survival was obtained at a rearing temperature of 28 °C (80.00%), where this value was significantly different from other treatments. Therefore, with economic considerations, it is concluded that the optimal larval rearing media temperature is 28 °C.

“…However, due to their morphological similarity and overlapping diagnostic characteristics, their taxonomy is still ambiguous and confusing, and the phylogenetic relationships of Lutjanus species remain obscure [ [4] , [5] , [6] ]. Accurate species identification is essential for further research on life history, stock assessment and stock management [ 7 ].…”
