The composition in different size groups, and index of relative importance of Callinectes amnicola food from Okpoka creek was studied for a period of two years (January 2006 -December 2007). Crabs less than 10mm were absent in the catch. Crab appendages, bivalve shells, bivalve tissues, gastropod shells and annelids were absent in smaller crabs (10-19.9 mm) and (20-29.9 mm). Algae cells were absent in crab (40-49.9 mm to 70-79.9 mm) size groups. Crustacean, Pisces and mollusca were common in…

Growth pattern, condition factor, trace metal studies and ectoparasitic load of the blue crab, Callinectes amnicola from Lagos Lagoon, Badore, Ajah, Lagos, Nigeria
TLDR
Carapace length, growth pattern, condition factor and ectoparasitic infestation may be used to discriminate among sexes of C. amnicola and this study shows relatively low concentrations of trace metals compared to the WHO limits.
Filling in data gaps on the phaeton dragonet [Synchiropus phaeton (Günther, 1861)]: a study on biological characteristics in the eastern Mediterranean (Aegean Sea, Greece)
ABSTRACT The main objective of this work is to provide information on the age and growth, gonadal maturity and the feeding habits of the phaeton dragonet [Synchiropus phaeton (Günther, 1861)] in the

TLDR
A synthesis of the current understanding pertaining to the diversity, biology and exploitation of these crabs in order to identify promising research paths for this zoological group is presented.
Terrestrial insects as the main food for freshwater fish in Sungai Kerian tributaries: an implication on habitat conservation
The importance of terrestrial insects as food items for freshwater fish was studied by examining stomach contents of Devario regina (Fowler 1934) and its population parameters at canopied areas of
Feeding ecology of broadbill swordfish (Xiphias gladius) in the California Current
TLDR
The feeding ecology of broadbill swordfish in the California Current was described based on analysis of stomach contents collected by federal fishery observers aboard commercial drift gillnet boats from 2007 to 2014, with jumbo squid being more important from 2007-2010 than in 2011-2014.
Index of relative importance of diet components in Mastacembelus armatus (Lacepède, 1800) from Karapuzha Reservoir, Wayanad, Kerala, India
TLDR
The dietary analysis of the spiny eel showed that the fish subsisted mainly on small forage fishes, and the index of relative importance (IRI) values indicated that fishes and prawns were the major diet components.

Comparative Study of the Diets of the Blue Crabs Callinectes similis and C. sapidus from a Mud-Bottom Habitat in Mobile Bay, Alabama
TLDR
Relatively high percentage of dietary overlap between C. similis and C. sapidus suggests that these crabs probably utilize common resources in areas of habitat overlap in Mobile Bay, Alabama.

TLDR
Evaluating the variations in trophic relationships among species of blue crabs from Tamiahua Lagoon, Mexico, may lead to a better understanding of the mechanisms that enable closely related species to exploit the same Trophic niche.
Food Habits of the Blue Swimming Crab Portunus pelagicus along the Coast of Dar es Salaam, Tanzaniajpeg
TLDR
The food habits of the blue swimming crab Portunus pelagicus were investigated using the stomachs of 3948 crabs collected from Kunduchi sub-littoral shallow waters, Msasani Bay and Mzinga creek along the coast of Dar es Salaam.
Feeding activity of Callinectes ornatus Ordway, 1863 and Callinectes danae Smith, 1869 (Crustacea, Brachyura, Portunidae) in Ubatuba, SP, Brazil
TLDR
The obtained results support higher feeding activity at night in these species and indicate short time for extracellular digestion, not exceeding 8 h.
Analysis of stomach contents of the porbeagle shark (Lamna nasus Bonnaterre) in the northwest Atlantic
TLDR
The porbeagle is primarily an opportunistic piscivore with a diet characterized by a wide range of species and diet composition changed seasonally following a migration from deep to shallow water.
The swimming crabs of the genus Callinectes (Decapoda: Portunidae)
TLDR
The genus Callinectes and its 14 species are reevaluated and a fresh look is taken at the component species in order that major areas of study such as fisheries biology, ecology, zoogeography, embryology, and physiology can proceed on a stable nomenclatural basis.
Diet composition and food habits of demersal and pelagic marine fishes from Terengganu waters, east coast of Peninsular Malaysia
TLDR
A "conceptualo food web structure" indicates that fish species in the study area can be classified into three predatory groups: predators on largely planktivorous or pelagic species; predator on largely benthophagous or demersal species; and mixed feeders that consume both pelagic and demeral species.
