“…Z. faber are opportunistic species which consume mainly abundant and diverse species according to habitat. Similar results are observed in other fishes, Lophius litulon (Choi et al 2011;Park et al 2014), Coryphaena hippurus (Jeong et al 2017), and Muraenesox cinereus (An et al 2011).…”

Background: Most fish undergo prey switch from juvenile to adult. It is thought that slightly different feeding habits occur among adult fishes due to growth, spawning, habitat change, and so on. Therefore, the diet of the John Dory Zeus faber (≥ 24 cm TL) was studied in the coastal waters of Korea by analysis of stomach contents, with comparison by season and size class of diet composition and prey diversity. Monthly samples were taken from February 2017 to January 2018. Results: The results showed that the John Dory was a piscivorous predator, and pisces had occupied 82.3% of IRI%. Trichiurus lepturus and Trachurus japonicus were important preys in all size classes and seasons. Diet composition differed among the size classes and seasons (Chi-square test, P < 0.05). As body size of Z. faber increased, the occurrence of benthic fish (Glyptocephalus stelleri) tended to increase. The seasonal prey composition also changed depending on the abundant species of each season. Conclusions: Z. faber is a piscivorous predator. The consumption habits of Z. faber appear to different results by their size and seasons. This study suggests that Z. faber could be considered an opportunistic predator.

“…T. kammalensis is a ram filterer. Many fish species use the most abundant prey resources in their ambient environment (Park et al 2014). Prey behavior can also determine the diet of a predator, as it influences catch success and encounter probability (Persson & Diehl 1990).…”

“…Therefore, a study on T. kammalensis is necessary for the systematic management and conservation of this stock, as well as to understand trophic relationships because this resource might decrease drastically. Fishery biology studies are very useful for understanding aspects of species biology and ecology for the sustainable management of stocks and the development of conservation measures (Park et al 2014). T. kammalensis is a very important fishery resource in Korea both economically and ecologically, but despite its importance, little is known about the ecology and biology of T. kammalensis, other than a description and data on the ontogeny of its young from Peninsular Malaysia (Sarpédonti et al 2000) and the abundance and distribution of T. kammalensis larvae in relation to ontogeny and environmental factors in a Malaysian estuary (Sarpédonti & Chong 2008).…”

The feeding habits of Thryssa kammalensis was studied using 430 specimens collected from October 2010 to September 2011 in the coastal waters of Gadeok-do, Korea. T. kammalensis in the coastal waters of Gadeok-do was carnivorous predator and planktonic feeder with a wide variety of prey items such as arrowworm, copepods, crab larvae, shrimp larvae, and fish eggs. In addition, T. kammalensis consumed mainly arrowworm, copepods, crab larvae, shrimp larvae, fish eggs, and the diet also included small quantities of cladocerans, amphipods, bivalve larvae, mysids, and euphausiids. On the other hand, the body length (BL) of T. kammalensis specimens ranged from 5.9 to 15.1 cm. Size-related variations in dietary composition of T. kammalensis were not significant that overlap indexes of each major food items that showed very high values in all size classes, representing more than 0.80. Arrowworms were the dominant prey item in all sizes, and copepods were the next most frequent prey item consumed in all size classes. Seasonal changes in dietary composition of T. kammalensis were significant. However, overlap indexes of each major food items in some season showed very high values of 0.80 (between spring and winter) and 0.85 (between summer and autumn). Copepods were most frequently eaten in the spring and winter. Moreover, arrowworm were the dominant prey item in summer and autumn. Mean numbers of prey per stomach (mN/ST) changed significantly with size groups (P < 0.05), but mean wet weight of preys per stomach (mW/ST) showed an opposite tendency (P > 0.05).

Specimens of Callionymus beniteguri (n=89) were collected from the waters off the coast of Taean, Korea, between April 2008 and January 2009, and their feeding behavior was observed. C. beniteguri (4.0-15.5 cm SL) was found to be a bottom-feeding carnivore that primarily preyed on gammarid amphipods, and secondarily consumed polychaetes but also ingested bivalves, shrimps, cumaceans, and sea urchins. Six additional minor prey groups also contributed to its diet, but the index of relative importance (IRI) for these groups was relatively low (<1.0). C. beniteguri exhibited size-related dietary changes. Small individuals (<10 cm SL) mainly consumed amphipods. As fish size increased, amphipods tended to decline in IRI, while the contributions of bivalves, sea urchins, and polychaetes became more important.
