“…Tilapia was purchased from aquarium keepers and individuals of length 6.1 (± 2.8) cm were chosen for the experiments in this study. As some of our own earlier studies have indicated that familiarity with individual fish can influence shoaling decisions in this species (Binoy and Thomas 2006;Binoy et al 2015), the absence of tilapia in the sites, from which the study climbing perch was collected, and in neighbouring areas was ensured by interviewing the local fishermen.…”

“…Shoal-choice experiments were conducted in an apparatus consisting of an aquarium (85 × 32 × 32 cm), divided into two side chambers (16 × 32 × 32 cm) and a central chamber (53 × 32 × 32 cm) with transparent Plexiglas sheets with perforations (Binoy et al 2015). Three sides of the aquarium were covered with black paper and water filled up to a height of 28 cm.…”

“…Each subject fish was given six min to assess the stimulus shoals before it was released into the central chamber by raising the presentation cage. Time spent by the subject fish in the 'preference zone' (area within 5 cm from either of the stimulus shoals) during the test time (6 min) was taken as the indication of its preference for the shoal present in the adjacent chamber (Binoy et al 2015). We used each subject fish only once.…”

“…In Kerala, the southernmost state of India, many natural water bodies, including those located in biodiversity hotspots (Raghavan et al 2008), now harbour fast-growing populations of tilapia, who share these habitats with several native species, including the climbing perch Anabas testudineus. Our previous laboratory studies have demonstrated that climbing perch can acquire familiarity with a shoal of conspecific individuals and possess the ability to distinguish an isolated, familiar conspecific from an unfamiliar one; such familiarity subsequently influenced the shoaling decisions of the species (Binoy and Thomas 2006;Binoy et al 2015). Hence, there is a strong likelihood that native populations of climbing 6 perch could develop familiarity-dependent preference for shoals of invasive, alien heterospecifics and vice versa if the probability of them coming in contact is significantly high.…”

The biodiversity of freshwater aquatic ecosystems is threatened by invasive alien species across the world. We studied the impact of the presence of an invasive piscine species, the tilapia Oreochromis mossambicus and acquisition of familiarity with it on the social decision-making and exploratory behaviour of a native, air-breathing, freshwater fish, the climbing perch Anabas testudineus. Our results reveal that the climbing perch did not show any significant preference or aversion to any of the stimulus shoals when unfamiliar monospecific shoals of tilapia, mixed-species shoals of tilapia and climbing perch that were divergent in the composition, or groups comprising only tilapia familiar to the subject fish for a duration of 30, 60, 90 or 120 days, were presented in opposition to a shoal with an equal number of unfamiliar conspecific individuals. No preference for isolated familiar individual tilapia was also observed against its unfamiliar counterpart or a conspecific individual. It is also noteworthy that the propensity of subject climbing perch to initiate exploration of a novel area (a measure of boldness) or exploratory activity and its sociability remained unchanged under different social conditions, including presence of unfamiliar conspecific, familiar conspecific, unfamiliar heterospecific or familiar heterospecific individuals. These results are discussed in the light of ever-increasing levels of invasion by alien fish species and the struggle for survival that currently confront native piscine species in most tropical freshwater ecosystems globally.

The Banggai cardinalfish Pterapogon kauderni is an endangered endemic species with an exceptionally small native distribution and an unusual life history. A paternal mouthbrooder with direct development, symbiosis with benthic organisms (referred to as microhabitat), is crucial to its survival. This is especially so for postflexion larvae (recruits), after their release from the male parent’s buccal cavity. Microhabitat preference in P. kauderni has been studied empirically based on a survey of wild populations. This study adopted an ex-situ experimental approach to P. kauderni microhabitat preference using two well established behavioural trial methods: choice flume and choice tank. The experimental animals were sourced from the introduced P. kauderni population in Palu Bay, Central Sulawesi, Indonesia. The choice flume method was applied at the Central Sulawesi Marine and Fisheries Service Hatchery in Mamboro, Palu, with microhabitats Diadema setosum and D. savignyi. The choice box method was applied at the Universitas Hasanuddin Centre for Research and Development in Makassar, South Sulawesi, Indonesia, with microhabitats Heteractis crispa, Entacmaea quadricolor, D. savignyi and D. setosum. The results indicate the most to least preferred preference hierarchy of D. savignyi, D. setosum, H. crispa, E. quadricolor. While the preference for the sea anemone H. crispa compared to E. quadricolor is consonant with empirical in situ studies on P. kauderni, the observed preference for D. savignyi over D. setosum was unexpected, and points to the need for further research. Observations made during the trials also raise the possibility that imprinting may occur and influence subsequent microhabitat preference.

1 climbing perch Anabas testudineus, a freshwater fish 2 3 4 Abstract 32 A unique piscine behaviour-collection and temporary storage of food materials inside 33 the mouth during times of availability and particularly in response to starvation-has 34 been reported in a single species, the climbing perch Anabas testudineus. In this study, 35 we documented a significant variation in the amount of food collected by populations of 36 climbing perch inhabiting different ecological regimes, kole paddy fields, canals and 37 water channels in coconut plantations, after experiencing starvation for two different 38 periods of 24 and 48 h. Our results revealed a significant flexibility in this unique 39 behaviour, depending on the ecological conditions and hunger experienced by the 40 individuals. 41 42 Keywords Feeding behaviour .
