“…In addition to competing for resources, interfering with reproduction and introducing parasites (Arthington 1991, Crowl et al 1992, Kennard et al 2005, Benejam et al 2009, Hazelton and Grossman 2009, mosquitofish are quite aggressive and often attack fish more than twice their own body size (Wurtsbaugh et al 1980, Howe et al 1997). Because of their higher dispersal tendency, invasiveness (Rehage and Sih 2004) and adverse effects on native aquatic communities (Barrier and Hicks 1994, Webb and Joss 1997, Arthington and Marshall 1999, Smith et al 2011, the database of the IUCN Invasive Species Specialist Group (www.issg.org/database) classifies mosquitofish, along with eight other species, as among the world's 100 worst invasive species ISSG, 2000;Lowe et al 2000). Invasive exotic species may displace native species through resource competition or by overexploiting native species to the point of extinction (Dahms 2004, Clavero andGarcía-Berthou 2005) or they may alter the habitat to such an extent that native species are no longer able to exist (Dahms 2005, Gooden et al 2009).…”

Background: Mosquitofish were introduced to several countries of the tropics and subtropics as biological agents for the control of mosquito larvae. Meanwhile, they became a threat to native communities and fish worldwide, similar to other invasive species through resource competition, overexploitation, or habitat alteration. We investigated prey selectivity patterns of Gambusia affinis (mosquitofish) preying on larvae of the two Indian major carps (Catla catla and Labeo rohita) in the presence of varied proportions of alternative prey (rotifers, cladocerans, chironomid and mosquito larvae) under laboratory conditions. Results: The patterns of prey selectivity in mosquitofish were influenced by the presence of alternative prey and their relative abundance in the environment. Carp larvae, when present in equal proportions, were randomly selected by mosquitofish, however, positively selected when present in higher proportions. In the presence of Hexarthra mira, Daphnia similoides or the mosquito larval instar-IV as an alternative prey, the mosquitofish preferred fish larvae regardless of prey proportions. In the medium where either mosquito larval instar-I or chironomid larvae were given as alternative prey, the mosquitofish either rejected or randomly selected the carp larvae. Given a multispecies prey combination, mosquitofish primarily selected the larvae of L. rohita and mosquito larval instar-I. We also found a prey switching ability of mosquitofish in relation to varying abundances of prey species in the environment. Conclusions: The present results suggest that mosquito immatures are not the preferred food of mosquitofish when fish larvae are present in their natural habitats. Since mosquitofish and carp larvae have overlapping natural habitats and prey preferences are the invasive mosquitofish may have a substantial impact on native communities of invertebrates and fish. This way, they are equally important for extensive fisheries and conservation management.

“…Lithobates spehnocephalus tadpoles exposed to visual cues and chemical cues of mosquitofish grew slower than control tadpoles or those exposed only to chemical cues (Collier et al, 2008). In addition, other anuran tadpoles have been shown to decrease their activity in response to cues from G. affi nis (Lawler et al, 1999;Smith et al, 2010Smith et al, , 2011, although not all species show such a response (Smith et al, 2008(Smith et al, , 2009Buttermore et al, 2011).…”

Pollutant exposure can affect tadpole activity or affect their ability to respond to predator cues. One commonly used chemical in aquatic ecosystems, particularly those in suburban or rural areas, are dyes used to color or tint pond water. Little is known about how such dyes impact amphibians. We examined the effects of Tetra Pond Water Shade pond dye on the activity and behavioural response of Southern Leopard Frog (Lithobates sphenocephalus) tadpoles to cues from a potential predator, the Western Mosquitofish (Gambusia affi nis). Tadpoles of L. sphenocephalus reduced activity after exposure to cues from G. affi nis. The pond dye did not affect the activity or response of L. sphenocephalus tadpoles to G. affi nis cues. Our results suggest little impact of this dye on the behavior of L. sphenocephalus at concentrations up to twice the recommended usage.

“…Nilai nitrat cenderung turun di akhir pemeliharaan hal ini disebabkan proses nitrifikasi baru berlangsung dan nitrat yang merupakan nutrien bagi pertumbuhan baru dimanfaatkan oleh tanaman. Konsentrasi nitrat dalam perairan berkisar 0,1−5 mg/L (Smith et al, 2011), nilai nitrat yang didapat pada kontrol dan perlakuan masih berada dalam kisaran normal sehingga masih baik untuk kehidupan ikan gurami.…”

ABSTRACT The use of high stocking density in nursery causes a decrease of water quality. Technology that can be used to solvethe low water quality in nursery of giant goramy was phytoremediation using Pistia stratiotes L. Purpose of this research was to determine the best weight ratio between P. stratiotes L. and 33 L water in nursery giant goramy size 3 cm. Giant goramy size 3 cm was maintained in an aquarium and was treated with different weight of P. stratiotes L. consisted of 45 g, 90 g, 135 g, and controls P. stratiotes L. 0 g. Cleaning and water change was done once a week. This research showed that the treatment of P. startiotes L. 45g/33 L water gave the best result in survival rate, absolute length of the growth, specific growth rate, feed efficiency and economically profitable. Keywords: phytoremediation, water lettuce, Osphronemus goramy L., nursery ABSTRAK Penggunaan padat tebar tinggi pada pendederan ikan gurami mengakibatkan kualitas air menjadi buruk. Salah satu teknologi yang bisa digunakan untuk mengatasi kualitas air yang buruk pada pendederan ikan gurami adalah fitoremediasi menggunakan tanaman kayu apu. Tujuan penelitian ini adalah menentukan bobot kayu apu dengan volume air 33 L pada pendederan ikan gurami ukuran 3 cm. Ikan gurami ukuran 3 cm dipelihara di dalam akuarium dan diberi perlakuan bobot tanaman kayu apu berbeda yaitu 45 g, 90 g, dan 135 g, serta kontrol (kayu apu 0 g). Penyiponan dan pergantian air dilakukan setiap satu minggu sekali. Hasil penelitian menunjukkan bahwa perlakuan kayu apu 45 g/33 L air menunjukkan hasil tingkat kelangsungan hidup, pertumbuhan panjang mutlak, laju pertumbuhan bobot harian, efisiensi pakan yang paling baik, serta lebih menguntungkan dibandingkan dengan perlakuan kontrol (kayu apu 0 g).
