The shape and size of skull and arrangement of mouth parts play an important role to determine the food and feeding behaviour of birds. The cephalic or head index is a ratio between breadth and length of head. The numerical procedure of cephalic indices of birds represent an important taxonomic character and also help to establish the relationship of feeding habits to visual and acoustic organs of birds. Birds have evolved a great variety of beaks according to their food habits. Due to different food habits found in birds, they possess various types of beaks of special structure. This article deals with cephalic indices of some birds of Uttar Pardesh (India) in relation to their feeding habits.

The Relationship

The relationship between carapace length (CL), carapace width (CW) and total weight (TW) in the flower moon crab Matuta planipes Fabricius, 1798 was studied and found to be CL = 0.144+1.319 CW and CL = 0.356+1.273 CL for males and females respectively. In case of the carapace width and total weight, the relationships were: TW = 0.272 CW3.011 and TW = 0.474 CW2.555 for males and females respectively. The relationships of carapace length and total weight were: TW = 0.128 CL2.917 for males and TW = 0.184 CL2.650 for females. A linear pattern was found between the relationship of CL and CW for M. planipes, whereas a curvilinear pattern was found between the relationship of CL/CW and TW in the present study. It was also observed that M. planipes is an opportunistic omnivore, seaweed being the most dominant food item followed by crustaceans, seagrass, amphipods and miscellaneous matter.

Part I. The Medulla Oblongata, And Its Variations Acoording To Diet And Feeding Habits In previous communications to this Society the relationship of the habits of feeding and diet to the form and pattern of the medulla oblongata has been described in the cyprinoids, clupeids, and gadoids (Evans, 1931, 1932, 1935). This research takes up a similar study of the brain of the Pleuronectidae. The expense has been borne by a grant from the Royal Society for which the author tenders his grateful thanks. It has seemed to be desirable to extend the observations to the fore- and mid-brain, as in some members of the family these present a very marked development. In order to elucidate some of the problems that arise I have also studied the brain of the eel, and some interesting conclusions have resulted. We find, as a result of examination by the naked eye and of serial sections, that we can divide the following species into four groups as follows: I. The sole, Solea vulgaris .

Potential Food

Food and feeding habits of fishes have a great significance in aquaculture practices. It helps to select such species of fishes for culture which will utilize all the available potential food of the water bodies without much competition with one another but will live in association with other fishes. This paper deals with the feeding intensity and food habits of L. bata . Food and feeding habit of freshwater minor carp Labeo bata (120 to 250 mm total length) were studied. The fish is a herbivore, feeding mainly on algae (22.32 %), higher plant parts (31.26 %), protozoans (7.42 %), crustaceans (15.33 %), insects (3.56 %), muds, sand, debris and detritus (16.32 %) and unidentified food materials (3.99%).Journal of Science Foundation, 2014;12(1):7-15

Food habits of the swamp deer (Rucervus duvaucelii duvaucelii) were studied in and around Jhilmil Jheel Conservation Reserve (JJCR), Uttarakhand, for two years. This population (320 in number) was recently rediscovered in the state (2005) and warranted an ecological study because the habitat around this study area is heavily fragmented due to expansion of agriculture, habitation, and various other land use practices. Therefore, this study was initiated by the major objective of studying seasonal variation in food habits of swamp deer. Proportionate food consumption was studied using feeding quadrat method. The study reveals that the overall diet of swamp deer consisted mainly of graminoids (grasses and sedges) and herbs (terrestrial and aquatic). In the protected areas studied earlier, the swamp deer habitat was dominated by grasses, and hence they were reported to be predominantly a grazer who occasionally fed on aquatic plants (Schaller 1967 and others). In contrast, at Jhilmil, the area also has equal presence of other plant types namely, sedges and terrestrial herbs. This resulted in polyphagous feeding habit of animal here.

Knowledge on fish biology is essential for improving aquaculture. The present study was focused on the biology of Puntiusamphibius. The fishes were collected from a freshwater body in parlance known as “Arappa”, located in Thalikulam at Thrissur district in Kerala. This water body is in the vicinity of the sea anddebouches into the marine during monsoon season. In the present investigation 106 fishes were collected during March to August 2006. The study revealed that there was no significant difference observed among the length weight relationship of males and females. Composition of gut content showed that it is a selectivefeeder of Bacillariophyceae and a pronounced omnivore. The gastro-somatic index of female and male was high during May indicating the active feeding during breeding.The sex ratio between males and females was variable and female dominated over males. The fecundity of fish was proportional to the weight of the ovary. Gonado-somatic index was comparatively high during spawning seasons. This is a preliminary lesson on the reproductive biology and certain distinctive characters such as length-weight and food and feeding habits of Puntius amphibius.

Abstract Unrevealing food and feeding habits of fishes is the centre of research in aquatic biology, ecology, conservation biology and fisheries. The current practice in feeding ecology of fish accredits it as descriptive ecology, relying primarily on the information of their diet, directly through gut analysis or indirectly by computing some diet based indices. Such methods often mislead in the understanding of the true feeding behaviour of organisms need for more reliable and functional approach. The main objective of feeding ecology is to evaluate feeding behaviour of fish. Recent developments in tools and techniques of analytical research is an opportunity to take up more reliable details by formulating affordable methodical design for recording, modulating and designing suitable approaches for better explanation of the feeding biology in fish.

Ficopomatus talehsapensis, a new brackish-water species (Polychaeta: Serpulidae: Ficopomatinae) from Thailand, with discussions on the relationships of taxa constituting the subfamily, opercular insertion as a taxonomic character and their taxonomy, a key to its taxa, and their zoogeography

A new brackish-water serpulid polychaete species belonging to the genus Ficopomatus from Thailand is described. It had previously been identified as another known species belonging to the same genus. Taxonomic problems within the subfamily Ficopomatinae to which it belongs and the relationship of the genus Marifugia and its single known species which occurs in freshwater are discussed. While the other known genera of the subfamily possess seven thoracic chaetigers, Marifugia has six, but agrees with the former with regard to all other important characters. Likewise, among typically marine taxa, the genus Pomatoleios has six thoracic characters but agrees with the genera Pomatoceros and Spirobranchus with regard to all other important characters. As there are also other known serpulid genera having six thoracic chaetigers, an analysis was undertaken of 10 genera, six of them having six thoracic chaetigers and the remaining four seven. It revealed that Marifugia is the sister to the clade containing the other two genera of the Ficopomatinae (Neopomatus and Ficopomatus) and Pomatoleios is sister to the clade containing Pomatoceros and Spirobranchus. The usefulness of opercular insertion/derivation from a particular branchial radiole as a character in serpulid taxonomy is discussed. As observed in adults and juveniles of species belonging to ficopomatine genera, as well on available evidence on post-larval development, their opercular insertion is in the position of the first branchial radiole, unlike in genera such as Pomatoceros and Hydroides where it is on the second. A key to the known taxa of the subfamily is provided. Although they may be geographically separated by oceanic and/or terrestrial barriers, their common characters, including their ability to survive and propagate in their respective typically non-marine habitats, are indicative of their monophyly.

Food and feeding habits, sex ratio, spawning behaviour, size at first maturity, fecundity and ova diameter of the shrimp scad Alepes djedaba (Forsskal, 1775) exploited off Cochin coast, Kerala are presented in this study. A. djedabat is a pelagic carnivore, with a preference for fishes. Low gastrosomatic index (GaSI) values and very low feeding intensity during spawning season indicated poor feeding behaviour during the period. The sex ratio did not deviate from the expected 1:1 ratio. Size at first maturity was estimated to be193 mm for male and 174 mm for female. Monthly gonadosomatic index (GSI) values, monthly distribution of gonadal maturation stages and ova diameter revealed that the species had a prolonged breeding season from June to September with a peak in July. Estimated absolute fecundity was 59,744 to 3,30,190 with an average of 1,94,965 eggs.
