For example, there are reefs in the remote Northwestern Hawaiian Islands where huge aggregations of top predators like Galapagos sharks (Carcharhinus galapagensis) and Giant Trevally (Caranx ignobilis) appear to represent far greater biomass than the smaller reef fishes and invertebrates these predators feed upon.
Crevalle jack (Caranx hippos) is a marine fish found in tropical and subtropical zones worldwide.
High bioaccumulation of Hg occurred consistently in carnivorous fish species, particularly piscivorous Caranx ignobilis.
Thus, the aim of this study was to purify and to characterize a trypsin from the processing by-products of crevalle jack (Caranx hippos) fish.
The red snapper, Lutjanus goriensis, Caranx hippos, Schilbe mystus, Mugil curema, Ethmalosa fimbriata, Galeiodes species, etc., were only found in Site 3 as shown by the CCA multivariate analysis (Fig. 3).
Horse-eye jacks (Caranx latus) and bar jacks (Carangoides ruber) routinely school around Caribbean reef sharks.
Prey resources in shallow lagoon habitats at FFS may be insufficient to support high numbers of predatory teleosts (e.g. giant trevally, Caranx ignobilis) as well as sharks.
We saw several species for sale at the market that were not found during our collections (e.g. Caranx sexfasciatus, Megalops cyprinoids, Moolgarda seheli, Rastrelliger kanagurta and Euthynnus affinis).
Fishes classified as piscivores included snappers (Lutjanus spp ., needlefishes (Strongylura spp ., groupers (Epinephelus spp ., great barracuda (S. barracuda), Atlantic tarpon (Megalops atlanticus), and jacks (Caranx spp .. Invertivores such as grunts (Haemulon spp).
In 2005 and 2006, respectively, 59 (17%) and 94 (28%) households reported that they avoided eating crevalle jack (Caranx hippos), and 5 (1%) and 7 (2%) avoided hogfish (Lachnolaimus maximus), because they believed that these fish might be ciguatoxic.
Recording abundance of several key fisheries species which are indicative of healthy reefs, including large groupers (Epinephelus polyphekadion, Plectropomus leopardus), jacks (Caranx melampygus) and sharks (Carcharhinus melanopterus), may provide more fine scaled environmental monitoring than simply presence or absence data [ 29].
