“…The mean river water temperature at Huntly is 16.4 °C (minimum 10.6 °C, maximum 22.1 °C) and mean annual flow at Huntly is 334 m 3 s −1 (Environment Waikato monitoring data, EWMD). The catchment use is predominately pastoral farming and there are major inputs of treated sewage and stormwater run‐off from urban areas (West, Ling, Hicks, Tremblay, Kim & van den Heuvel 2006). Koi carp is restricted to the lower reaches of the Waikato River below the hydro‐electric dam at Karapiro, south of Cambridge.…”

Koi carp is an ornamental variant of the common carp, Cyprinus carpio L., that was introduced to New Zealand in the 1960s and has since become a major aquatic pest. A total of 1265 wild adult koi carp were caught by boat electric fishing, dart tagged and released at multiple sites in the lower Waikato River and associated lakes and wetlands between September 2002 and February 2005. Subsequent recaptures by boat electric fishing and recreational fishing returned 76 koi carp (6% of all tagged fish). Of these, 85% were recaptured less than 5 km from their release site; only one fish moved more than 50 km. On seven occasions, pairs or small groups of koi carp (20% of all tag returns) that had previously been tagged and released at the same locations and times were subsequently recaptured together after considerable periods of time at liberty (mean 551 days ± 419 SD). Adult koi carp in the Waikato River showed a high degree of site fidelity, exhibited prolonged social groupings and females moved downstream more often than males.

“…En este caso, el uso y desarrollo de biomarcadores han cobrado un interés creciente para evaluar el riesgo de una sustancia o mezcla quí-mica potencialmente tóxica, ya que los biomarcadores constituyen valiosos parámetros o indicadores de la presencia de sustancias exógenas o cambios biológicos como respuestas a distintos xenobióticos (West et al, 2006), donde finalmente toda evaluación a realizarse tanto de parámetros físico-quími-cos, contaminantes de interés y en biomarcadores, podrían analizarse, simultáneamente ,con predicción de riesgo para un determinado ecosistema.…”

Pollution of aquatic ecosystems by heavy metals is a major environmental problem solving, because their analysis and interpretation on the relevance has finally resorting to biological matrices developed in natural environments. The aim of this research was to assess the ecotoxicology by exposure to heavy metals in the ecosystem San Juan Santiago de Cuba -Cuba. To do an investigation which lasted from May to November 2015, understanding this time the rainy period was performed. Abiotic sampling water matrix and the species was Gambusia punctata random probability, while quantitative technique used corresponded to structured observation. Continuous quantitative variables corresponded to dissolved oxygen, pH, electrical conductivity total solids, total alkalinity, total hardness and who were determined in-situ. In the case of chemical and biochemical oxygen demands they were analyzed under laboratory conditions. Concentrations of Cu, Zn, Pb and Cd were determined in water and bioaccumulate in gills, liver and brain BioMonitor. Wet elements quantitated by atomic absorption spectrometry by inductively coupled plasma axial view. It was noted that in general physicochemical parameters were found outside the allowable value by the regulatory standard used and in the case of the elements showed bioavailable concentrations, then finding bioaccumulate in target organs. Among the stations no statistically significant differences ( p ≤ 0.05 ) and can be interpreted as persistence and mobility conditions were observed in similar form. It was concluded that the waters of the San Juan ecosystem showed physicochemical to the availability of metals, conditions can be corroborated by bioaccumulation in the tissues analyzed, because there was ecotoxicological risk for the species that develops in a natural environment.Keywords: biomarkers , ecotoxicology, San Juan ecosystem, Gambusia punctata; chemical speciation, heavy metals, Santiago de Cuba -Cuba resumen La contaminación de los ecosistemas acuáticos por metales pesados es uno de los principales problemas ambientales por resolver, por cuanto su análisis e interpretación es sobre la relevancia en recurrir finalmente, a las matrices biológicas desarrolladas en ambientes naturales.

“…Other endocrine pathways may also be involved. Exposure has also been associated with increases in condition factor (K) [2,8] and changes in blood parameters [9,10], as well as both increases [7] and reductions [9] in the splenosomatic index, which has been used as a biomarker of disease or immune dysfunction in fish [11].…”

Adverse effects of pulp and paper mill effluent on fish populations have been well documented in many countries over the last two decades. Some of the initial studies were at mills with conventional chlorine bleaching and no secondary effluent treatment. Following installation of secondary treatment, changes in bleaching technology to elemental chlorine-free bleaching, and other process changes, adverse effects on fish were reduced or eliminated at some mills. Because no two mills are exactly alike, it is difficult to predict adverse impacts of any given mill on fish populations. In 1994, a study of female white sucker (Catostomus commersoni) in the Androscoggin River, Maine, USA, showed induction of mixed function oxidase, reductions in gonad size and plasma estradiol, and an increase in plasma testosterone in fish downstream of discharges from three large bleached kraft pulp and paper mills, and host community municipal sewage treatment plants (STP). After all three mills switched to elemental chlorine-free bleaching in the late 1990s, studies from 2001 to 2003 found that the pattern of reproductive impacts on white sucker populations measured in 1994 was not repeated. In addition, population estimates of white sucker from 2002 to 2003 using mark-recapture techniques found that densities and biomass were well within the range of those of a reference population, and of those reported in the literature for unimpacted populations. Detailed studies immediately above and below each mill/sewage treatment plant showed no evidence of reproductive effects. However, a clear pattern of eutrophication was noted, which increased cumulatively downstream below each mill/STP.
