“…The distinctive features of these "migrations" their purpose, and how they differ from the scattered and multidirectional movements of individuals are often not considered (Jamsari et al, 2010;Sheenaja and Thomas, 2011;Termvidchakorn and Hortle, 2013). At the same time, the context of use commonly explicitly or indirectly suggests a link between these movements of the climbing perch and its reproduction (Chanh et al, 2000;Poulsen and Valbo-Jørgensen, 2000;Pavlov and Zworykin, 2014;Zworykin, 2017).…”

The first report on terrestrial movements of amphibious fish was published at the end of the 18th century, but very little is still known about this behavior. Several hypotheses were suggested as to why amphibious fish leave the water, but none has been confirmed to date. Short overland movements of amphibious fish between water bodies occur during the rainy season, when weather conditions make this behavior possible. The spawning peak for these fish is in the same period. Some authors have recently linked these two phenomena, but the role of terrestrial locomotion as spawning migrations has not been really proven. Furthermore, overland movements of amphibious fish have sometimes been referred to as "lateral migration," which does not correspond to the definition of the term. Obviously, terrestrial movements ensure flexibility of life-history strategies in amphibious fish under habitat fragmentation. At the same time, these locomotions are most likely not migrations and are not always associated with spawning. A metapopulation approach to the study of life histories in amphibious fish appears to be promising. This conceptual framework would clarify both the population structure and dynamics, and the role of different types of movements in providing exchange between subpopulations.

“…Совокупность черт жизненной стратегии анабаса с некоторыми оговорками характеризует его как рыбу, для которой с наибольшей вероятностью можно ожидать следования так называемой оппортунистической стратегии [31], включающей в себя отсутствие заботы о потомстве. Одна-ко ряд особенностей биологии рыбы-ползуна указывает на возможность проявления ею родительского поведения [8]. Похожая ситуация характерна для змееголовов (семейство Channidae), относящихся к тому же отряду ползунообразных (Anabantiformes) и имеющих во многом сходную с анабасом репродуктивную биологию, включая мелкую плавучую икру, быстрое развитие и пр.…”

В частности, если бы было подтверждено наличие у него факультативной родительской заботы, это явилось бы свидетельством в пользу первого варианта эволюционного сценария.…”

Ползуновидные рыбы представляют собой уникальную группу, большинство представителей которой проявляют многообразную по формам заботу о потомстве. Реконструкция эволюции репродуктивных стратегий ползуновидных проблематична, что, в частности, связано с отсутствием достоверных подтверждений родительской заботы у ряда ее представителей, наиболее известным из которых является анабас. Более того, существуют прямые противоречия между литературными источниками по данному вопросу. В кратком обзоре представлен анализ вероятных причин разногласий, от прояснения которых зависит дальнейшее развитие представлений о филогенезе жизненных стратегий в группе ползуновидных и о возможных направлениях эволюционных преобразований размножения рыб в целом.

We examined sexual dimorphism and parental care in the chocolate gourami (Sphaerichthys osphromenoides) by visual observations, video recording of spawning, and histological analysis of the gonads of individuals in which spawning and mouthbrooding was previously observed. S. osphromenoides is considered a rare exception among labyrinth fishes (Osphronemidae family) because of the presumed maternal parental care, which is not found in other species of this family. According to our observations of 32 spawning events, parental care in this species was always performed by the male. Our visual observations were confirmed by video and histological analysis. This suggests that the sex in this species has probably been misidentified so far. We argue that the putative “females” (previously defined by external features) were in fact males, and that there are probably no exceptions to male parental care in osphronemid fishes.
