“…Cobitis loaches have been traditionally used as live bait by Iberian fishermen, a use that increased after the introduction of large piscivorous fish ( Micropterus salmoides and Esox lucius ) since the mid‐20th century (Collares‐Pereira et al, 2000). Live bait is generically forbidden, with few exceptions, in both Spain and Portugal, in spite of which fishermen in both countries admit using Cobitis loaches as live bait (Banha et al, 2017; Sánchez‐Hernández et al, 2018). In both cases, the percentage of fishermen admitting this use was low, but, as in the case of aquarium releases, these low proportion figures may involve a high number of potential introduction events.…”

“…The fourth species belonging to the subgenus Iberocobitis is Cobitis paludica. This is a widespread species, native to the central and southern regions of the Iberian Peninsula and introduced by fisherman to bodies of water along northern and southeastern Spain (Muñoz, 1993;Perea et al, 2011;Verdiel-Cubedo et al, 2012;Márquez-Rodríguez, 2014;Sánchez-Hernández et al, 2018). This wide distribution area is uncommon in Iberian freshwater fishes and high morphology and genetic diversity has been recorded in all studies regarding C. paludica (Perdices et al, 1995;Doadrio & Perdices, 1997;Doadrio & Perdices, 2005;Corral-Lou et al, 2022).…”

Three new species, Cobitis almadae sp. nov., Cobitis atlantica sp. nov., and Cobitis mellaria sp. nov. are described on the basis of morphological and genetic traits. Cobitis almadae sp. nov. is restricted to the Sizandro Drainage in Portugal and can be distinguished from other Cobitis species through a combination of morphometric and genetic traits including large and low peduncle depth, lateral ethmoid (suborbital spine) well developed with long narrow mediocaudal, laterocaudal and mediorostral processes, an elongated and narrow frontoparietal fontanel and a wide third Gambetta’s zone sprinkled with numerous black spots. Furthermore, two autapomorphies are found within its mitochondrial cytochrome b gene. Cobitis atlantica sp. nov. inhabits the northern Atlantic rivers of the Iberian Peninsula from the Minho Drainage to the Alcoa Drainage and can be differentiated from other Cobitis species through a set of morphometric and genetic traits including short and high peduncle depth,a well-developed lateral ethmoid (suborbital spine) with short and wide mediocaudal, laterocaudal and mediorostral processes, wide frontoparietal fontanel, and developed ventral pigmentation in adult individuals. In females, the Gambetta’s fourth row has 10-16 blotches reaching the ventral pigmentation in the caudal region and the third Gambetta’s zone is narrow with black spots. Cobitis mellaria sp. nov inhabits the Valle Drainage in southern Spain and is distinguished from other Cobitis species through the following morphometric and genetic traits: low peduncle depth, lamina circularis with convex outer edge, lateral ethmoid (suborbital spine) with short laterocaudal process and large mediorostral process, elongated frontoparietal fontanel, no ventral pigmentation in adults. In females, Gambetta’s fourth row has 10-15 blotches. One autapomorphy is found within the mitochondrial cytochrome b gene of Cobitis mellaria sp. nov.

“…The Southern Iberian spined-loach Cobitis paludica, henceforth loach, is an endemic species distributed throughout the centre and south of the Iberian Peninsula, from the Ulla and Ebro River basins towards the south (Doadrio et al 1988;Perea et al 2011;Sánchez-Hernández et al 2018). Their populations are declining throughout its range due to water and gravel extraction that result in habitat destruction, and to the introduction of exotic fish species (Elvira 1990(Elvira , 1995(Elvira , 1996Crivelli 2006).…”

Seasonal patterns of microhabitat selection in the Southern Iberian spined-loach Cobitis paludica

et al. 2022

The Southern Iberian spined-loach Cobitis paludica is an Iberian endemism threatened by human activities, including habitat destruction. For this reason, the development of conservation and the recovery plans for the species calls for a precise knowledge of its habitat requirements. Here, microhabitat use and selection patterns were investigated to determine the limiting factors for the species in different seasons, corresponding to a gradient in flow conditions. The microhabitat of the loach was analysed in the River Jarama (Tagus River basin, central Spain) in the period of maximum activity between March and September 2013. No significant differences in microhabitat use were found between males and females, and only very weak ontogenetic changes were detected. The microhabitat used by the loach varied significantly throughout the study period, generally adapting to the flow-mediated dynamics of available habitat. The most stable pattern throughout the year was the use of very low water velocities. Additionally, the loach made selective use of certain microhabitat features, with slight adjustments to the seasonally changing habitat conditions. The loach significantly selected positions with abundant silt substrate and aquatic vegetation, and avoided coarser substrates. The availability of fine substrates and abundant vegetation is therefore a critical habitat requirement for the loach, which needs instream structures that provide foraging substrate, refuge and safe positions for spawning. Selection of refuge elements (deep habitats, aquatic vegetation) was especially apparent under low-flow conditions. Human activities leading to the loss of these critical microhabitats may threaten the survival of already scarce loach populations.
