“…In contrast, omnivory predominates in tropical and subtropical lakes (Lazzaro, 1997;Jeppesen et al, 2007;González-Bergonzoni et al, 2012), except in some high-altitude tropical lakes in Ethiopia (Vijverberg et al, 2014). In addition, young and smallsized fish species that could potentially exploit zooplankton are mostly associated with the littoral zone in warm lakes (Fernando, 1994;Arcifa and Northcote, 1997;Meschiatti and Arcifa, 2002;Agostinho et al, 2003;Teixeira-de Mello et al, 2009), and are, therefore, segregated from the limnetic zooplankton.…”

INTRODUCTIONLong-term studies are essential for understanding ecological processes such as the influence of stressors and are basic for modeling, but are few in number because of their inherent difficulties, including costs (Jackson and Füreder, 2006;Maberly and Elliott, 2012). In particular, long-term studies of zooplankton can reveal the influence of past factors, including management decisions (Hambright, 2008). Some causes of changes in the zooplankton that are perceptible over a longer period include alterations of abiotic factors or predator invasion (Yan et al., 2008).The factors that affect the diversity and size of zooplankton species are intriguing issues, but still subject to controversy. From the classic paper by Brooks and Dodson (1965) to recent studies, several factors have been contemplated, and temperature has emerged as the preponderant factor for explaining latitudinal differences in zooplankton body size (Gillooly and Dodson, 2000). Gillooly and Dodson compared more than 1100 lakes located between 81°N and 77°S latitude, and found that the size variation of cladoceran species was related to latitude, with smaller sizes in the tropics and the Arctic and a greater difference between the tropics and the temperate zone. According to these authors, the highest mean sizes were observed between 6°C and 8°C, declining at higher or lower temperatures. Havens et al. (2015), comparing 122 lakes located from 6° to 74°N and from 19° to 21°S, showed a relationship between size (as weight) of cladocerans and cyclopoid copepods and temperature. In contrast, Iglesias et al. (2011) suggested that predation by fish is the major factor explaining the smaller size of zooplankton in warm lakes. Hart and Bychek (2011), in their extensive review of the many factors that could potentially influence zooplankton size, addressed extrinsic factors such as temperature, food and predation, amongst others, besides intrinsic ones. The authors concluded, however, that although a general pattern may occur, different results can arise from distinct ecosystems.J.

“…Thus the influence of fish on nutrient cycles could be greater during warmer seasons and at warmer latitudes. However, biomanipulations may actually be less effective at warmer latitudes because of the longer growing season, increased omnivory and increased risk of algal blooms (Jeppesen et al, 2007, Kosten et al, 2009, which may offset the gains made by fish reductions. Clearly, more research on biomanipulation efforts in tropical and subtropical systems is needed (Jeppesen et al, 2007).…”

“…Several reviews of European biomanipulations indicate that the removal of 80% of the total fish (primarily roach, Rutilus rutilus, and bream, Abramis brama) biomass (Hansson et al, 1998;Meijer et al, 1999;Jeppesen et al, 2007) or the removal of over 200 kg·ha −1 within a three year period (Søndergaard et al, 2008) increases the likelihood of success for a fish removal project. Thus, some authors have recommended that biomanipulation will be most effective in smaller lakes where there is an increased likelihood of removing a large portion of the fish biomass (Meijer et al, 1999;Jeppesen et al, 2007). The SJRWMD removals in Lakes Apopka and Griffin have been smaller on a kg·ha −1 basis than what was recommended by Søndergaard et al (2008), partially because of the large size of these lakes (Table I).…”

Key-words: Dorosoma cepedianum, biomanipulation, size-structure, nutrient excretionAlthough fish removal for biomanipulation is often highly size-selective, our understanding of the nutrient cycling effects of this size-selection is poor. To better understand these effects, we measured nutrient excretion by gizzard shad (Dorosoma cepedianum) of differing sizes from four central Florida (USA) lakes and combined these measures with gillnet biomass and size-structure data to compare lake-wide effects among lakes and years. Direct removal of P in fish tissue ranged from 0.16−1.00 kg·P·ha −1 ·yr −1 . The estimated reduction in P excretion due to harvest ranged from 30.8−202.5 g·P·ha −1 ·month −1 , with effects strongly tied to the biomass and size structure harvested. The amount of P release prevented per kg of fish removed was lower in previously unharvested lakes, due to the initial removal of larger fish with lower mass-specific excretion rates. Gill net mesh size impacted the size distribution of harvested fish, with smaller fish that excrete more P per gram being more vulnerable to smaller mesh sizes. In Lake Apopka, decreasing the mesh size by 1.3 cm yielded P excretion reductions that were 10.7−15.1% larger. Fish harvesting to reduce internal nutrient cycling can be most effective by increasing total harvest and by harvesting smaller size classes over multiple years. RÉSUMÉEffet d'une biomanipulation sélective en taille sur la libération des éléments nutritifs par l'alose noyer dans des lacs de Floride (États-Unis) Mots-clés : éléments nutritifsBien que l'enlèvement des poissons pour biomanipulation soit souvent très calibré, notre compréhension des effets sur le cycle des éléments nutritifs de cette sélection en taille est peu documentée. Pour mieux comprendre ces effets, nous avons mesuré l'excrétion des nutriments par l'alose noyer (Dorosoma cepedianum) de différentes tailles à partir de quatre lacs de Floride centrale (États-Unis) et combiné ces mesures avec la biomasse estimée aux filets maillants et les données de structure en taille pour comparer les effets à l'échelle du lac suivant les lacs et les années. Le retrait direct de P dans les tissus des poissons variait de 0,16 à 1,00 kg·P·ha −1 ·année −1 . La réduction de P estimée par excrétion due à la récolte variait de 30,8 à 202,5 g·P·ha −1 ·mois −1 , avec des effets fortement liés à la biomasse et la structure en taille du retrait. La quantité de P libérée évitée par kg de poisson prélevé était plus faible dans les lacs précédemment non pêchés, en raison de la suppression initiale de gros poissons avec des taux d'excrétion de masse volumique inférieure. Le maillage des filets a impacté la distribution en taille des poissons pêchés, les petits poissons qui excrètent plus de P par gramme étant plus vulnérables à des petits maillages. Dans le lac Apopka, la diminution de la taille des mailles de 1,3 cm a permis de réduire l'excrétion de P de 10,7 à 15,1 % en plus. Le retrait de poissons afin de réduire le cycle nutritif interne peut être plus e...

“…A question remains, therefore, on the applicability of biomanipulation techniques developed in higher latitudes to (sub)tropical water bodies. Numerous studies in temperate lakes where a more linear trophic chain prevails -piscivorous fish -planktivorous fish -zooplankton -phytoplankton -revealed the possibility of controlling phytoplankton through the trophic cascade effect (reviews by Lazzaro, 1997 andJeppesen et al, 2007). However, a recent revision showed not so promising results of the biomanipulation technique in some temperate lakes, in the long term.…”

“…However, that was an exceptional situation as both species are omnivores and not planktivores in most water bodies. Furthermore, the predominance of omnivorous fish in tropical and subtropical lakes (Lazzaro, 1997;Jeppesen et al, 2007;González-Bergonzoni et al, 2012) might lead to the direct exploitation of phytoplankton by fish (Starling, 1993a, b;Arcifa 2012), and develops blooms in eutrophic systems with high pH. It has also physiological adaptations to grow in low light intensities (Shafik et al, 1997), showing high absorption capacity of phosphate and ammonium (Padisák, 1997).…”

Aim: This study aimed to experimentally test the influence of a planktivorous filter-feeding fish (Tilapia rendalli) on the phytoplankton dynamics of a small and shallow tropical reservoir (Lake Monte Alegre, Brazil). Adults of T. rendalli of this lake feed preferentially on phytoplankton, and we hypothesize that: I) adults of T. rendalli will decrease the phytoplankton biomass and composition through direct herbivory, and II) as it is a eutrophic system, fish would not have strong influence on phytoplankton through nutrient cycling. Methods: To evaluate these different effects on algae, a field experiment was performed in the summer period for 15 days, in mesocosms isolated from the sediment, using a control group (no fish) and a treatment group (with one fish in each mesocosm). Physical and chemical variables and phyto-and zooplankton were evaluated at the start, middle, and end of the experiment. Results: At the end of the experiment, it was observed a significant increase in ammonium concentrations and total phytoplankton biomass, Cyanobacteria and Zygnemaphyceae and all size classes except class II (20-30 µm) in the treatment group (with fish). The biomass increase of the potentially toxic cyanobacterium Cylindrospermospsis raciborskii was also observed in the fish treatment at the end of the experimental period. Conclusion: This study did not support both initial hypotheses. It supports the assertion that in tropical water bodies, with similar characteristics to the environment studied, planktivorous filter-feeding fish, such as T. rendalli, are not effective in reducing phytoplankton biomass through direct grazing, even when phytoplankton is one of their main food items. T. rendalli can contribute to the increase of phytoplankton biomass and can promote or increase the eutrophication of aquatic systems.Keywords: mesocosm experiment, exotic omnivorous fish, direct grazing, nutrient increase.Resumo: Objetivos: Este estudo visou testar experimentalmente a influência de um peixe planctófago filtrador (Tilapia rendalli) sobre a dinâmica fitoplanctônica de um reservatório tropical pequeno e raso (Lago Monte Alegre, Brasil). Adultos de T. rendalli deste lago alimentam-se preferencialmente de fitoplâncton e nossas hipóteses são: I) adultos de T. rendalli reduziriam a biomassa e composição do fitoplâncton através da herbivoria direta, e II) como este é um sistema eutrófico, o peixe poderia não ter grande influência sobre o fitoplâncton através da ciclagem de nutrientes. Métodos: para avaliar esses diferentes efeitos sobre as algas, um experimento de campo foi feito no período de verão durante 15 dias em mesocosmos isolados do sedimento, usando um grupo controle (sem peixe) e um grupo tratamento (com um peixe em cada mesocosmo). As variáveis físicas e químicas e o fito-e zooplâncton foram avaliados no início, meio e fim do experimento. Resultados: No final do experimento, foi observado um incremento significativo nas concentrações de íon amônio, biomassa fitoplanctônica total, de cianobactérias e zignemaf...
