Dorsal- and anal-fin ray counts include both rays on last pterygiophore; gill raker
counts are presented as a total count followed by upper + angle + lower rakers in parentheses.
(2004) studied the gill raker
morphology and feeding ecology of two morphs of the European whitefish Coregonus lavaretus (Salmoniformes: Salmonidae: Coregoninae).
Scanning electron microscopy of the gill raker
of the Loricariid fish, Rhinelepis strigosa.
counts include rudiments and only a total count is given as it is difficult to determine which gill raker
is at the angle.
Wankowski (1979) and Qin and Fast (1998) also reported that feeding limitations occur in many fish larvae related to mouth gape width and gill raker
The distance between the gill rakers
of the first gill arch, the distance between the spines of the fourth gill arch, the number of gill rakers
per gill arch and the number of spines per gill raker
did not show homogeneous variances and were analyzed with a Kruskal-Wallis ANOVA followed by a multiple comparisons test of means by ranks.
Five morphological traits were measured as described in Schluter and McPhail (1992): body length, body depth, gape width, gill raker
number, and gill raker
Other characters were tested with the Kruskal-Wallis test and, with the exception of gill raker
length, all differed significantly between 2 or more species (Table 5).
The epicentre of the manta gill raker
industry is Guangzhou, China.
This paper deals with the small ossicles such as bony platelets, scutes, tubercles, prickles, ossified sensory line segments, oral and branchial denticles and ossified gill raker
tubercles of the cottoid families Cyclopteridae and Liparidae of the Baltic Sea.
As viewed using scanning electron microscopy, the sites of gill raker
removal had healed completely and the arches were smooth but undamaged.
and pyloric caecae counts for these two fish were within the ranges for sockeye salmon described by Scott and Crossman (1973).
