Food And Feeding

The food analysis of 150 specimens of Clarias batrachus revealed that the food consisted of insect larvae, small fish, shrimps and organic debris. Small fish and insect larvae were preferred as the primary food item in all the seasons. On average for all months of the study period, small fish dominated the list with a percentage of 30.27.The other food items in descending order are insect larvae (27.66%), worms (20.27%), shrimps (14.3%) and organic debris (7.05%).The feeding intensity in mature fishes was found to be very poor during August to September. This period of poor feeding activities in case mature fishes coincides with the peak spawning season.

The feeding ecology and prey preference of greenback grey mullet Liza subviridis (Valenciennes, 1836) were investigated in Parangipettai waters (11°29′25.55″N; 79°45′38.62″E) from May 2011 to April 2012. A total of 328 male and 360 female specimens of L. subviridis were analysed. Detritus and sand particles formed the major food item of L. subviridis in both sexes besides, diatoms, dinoflagellates, algae, zooplankton, foraminiferans, polychaetes and larval forms were also noticed and ranked respectively based on the quantities. Feeding intensity showed that the percentage of ‘empty’ stomachs varied from 7.2% (November 2011) to 19.3% (August 2011) and from 7.1% (March 2012) to 19.2% (August 2011) in males and females respectively whereas the ‘gorged’ stomach in males and females was in the ranges of 4.6% (March 2012) - 14.5% (December 2011) and 4.6% (September 2011) - 14.5% (April 2012). The gastrosomatic index of males and females ranged between 5.9% (October 2011) - 8.2% (May 2011) and 6.1% (March 2012) - 8.1% (May 2011) respectively. The results agree with the previous reports and extend the understanding on its well-being, reproductive seasons and stock of L. subviridis in Parangipettai waters.

Food items, preying and feeding activities of white-breasted Kingfisher, Halcyon smyrnensis were studied from September 2008 to September 2011 at Nikunja-1 in Dhaka City Corporation area. A total of 16 species of food items were recorded from the observation. Fishes (more than 60%) were mostly preferred item. The highest preference was fry of Labeo rohita (30.6%). They highly preferred the species belonging to the Family Cyprinidae and Order Cypriniformes. The length of the food items varied from 2.0 to 12.3 cm. Surface dweller species (85.8%) was highly preferred. During preying, they used 0.3 to 2.25 m height, among which the highest preference was 0.9 m (32%). H. smyrnensis targeted the food items before catching while they took 9 sec to 15 min 17 sec. After catching they either engulfed the prey immediately or hold it at their beak for 2 sec to 30 min 30 sec before engulfing. Bamboos found in the water body were mostly preferred (65.9%) as perching places during preying.Bangladesh J. Zool. 42(2): 237-249, 2014

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

The food and feeding habits of the redbelly Tilapia (Tilapia zillii) and Guenther’s mouthbrooder (Chromidotilapia guntheri) were investigated in an abandoned gold mine reservoir at Igun from June 2013 to May 2014. Using a cast net and gill-net fishing gears, 370 fish individuals were caught and their stomach contents were analysed by using the frequency of occurrence and numerical methods. Tilapia zillii comprised 53.78% (199 individuals), while Chromidotilapia guntheri covered up the remaining percentage (46.22%) which is made up of 171 individuals. Food items in the stomachs of T. zillii individuals predominantly consisted of detritus, mud and algae (77.97%), while those in C. guntheri individuals mostly consisted fish remains, detritus and algae (81.67%). T. zillii exploited more food items (23 of 27) as compared to C. guntheri (17 of 27). The Schoener’s index value for the species was 0.65. The study showed that T. zillii and C. guntheri exhibited benthopelagic exploitation and are mainly herbivorous and omnivorous respectively based on the food items observed in the stomach contents of these species. The fish species fed on related food items as confirmed by Schoener’s overlap index (0.65), suggesting that there was overlap in the dietary requirements of the two species. This index value, however, was probably not an indication of competition for food between these two species because they exploited abundant food sources.

In the northern part of its western Atlantic range, the swordfish feeds on relatively few species of fish. Volumetrically the most important species are Atlantic mackerel, barracudinas, silver hake, redfish, and Atlantic herring. Squid are also important in the diet, and accounted for nearly one-fifth of the volume in the stomachs examined. There is evidence that the swordfish frequently uses its sword to attack and disable even small individual food items before ingesting them.

The present study is aimed to provide information on the food and feeding habit of adult Auchenoglanis biscutatus in Lower River Benue. The natural food of A. biscutatus in the Lower River Benue was studied from stomach contents of the fish. The stomach contents were analyzed using two methods; the frequency of occurrence and point methods. A total of 100 stomachs were randomly examined. Eleven major items constituted the diet of A. biscutatus. The stomach content analysis of A. biscutatus have shown that they fed on the various food items ranging from plant parts, detritus, seeds, digested food particles, fish parts, mollusc, sand/mud, insect parts and algae. This indicates that A. biscutatus is an omnivorous bottom feeder since; bottom dwelling immature insects dominated most of the food items of animal origin, digested food and detritus. A. biscutatus in Lower Benue River feeds on a wide range of food items which could make it to be regarded as an omnivore. Future attempts to culture this species must take cognizance of its food habits in the wild.

Food and feeding habits of Gonialosa manmina were done by the analysis of 197 guts of the fish using both occurrence and point methods and also by the Index of preponderance. As per Index of preponderance, the preferred food items were graded as cladocerans (65.34%-1st), copepods (20.96%-2nd), miscellaneous (8.89%-3rd), rotifers (2.81% 4th) and bacillariophyceae (0.77% 5th). High feeding intensity was observed during pre and post spawning months. Significant (P<0.01) positive relationships were observed between the total length (TL) and total gut length (TGL) (TGL=2.09799TL0.89677, r=0.963, t=10.22), total length (TL) and stomach length (StL)(StL=0.18447TL0.7599, r=0.997, t= 39.92), and total length (TL) and intestine length (IL) (IL=0.99105TL1.0256, r=0.9854, t=16.37). Total fish length was slightly shorter than the gut length (1:1.31) and more than 91% animal nature gut contents confirmed that the fish was mainly a surface feeder zooplanktivore in Kaptai lake.

Feeding habits of P. laevigatus were investigated between February 1980 and November 1981 as part of a larger study on the structure of food chains supporting commercial fishes in the seagrass beds of Corner Inlet, south-eastern Australia. The main food components were crabs, predominantly Nectocarcinus integrifons, and juvenile fishes. Most dietary items were inhabitants of the seagrass zone. Small (25-33 cm) rock flathead showed a preference for fish, squid and shrimp whereas larger (> 33 cm) individuals consumed mainly N. integrifons together with some fish. Seasonal variations in diet and feeding intensity occurred. A decrease in feeding intensity in winter was accompanied by a shift in diet from N. integrifons to fish and squid. A second decline in feeding intensity corresponded to the apparent spawning period. The rock flathead and its main prey, N. integrifons, both showed a rhythm in locomotory activity correlated with nocturnal or crepuscular high tides whereas small fish prey were mostly active during daylight.

Small pelagic fishes play an important role in the ecosystem by linking planktonic production and higher trophic level predators, and provide a livelihood to both the small-scale and commercial fisher communities. This study analyzed the food and feeding habits of Stolephorus commersonnii (Lacepède, 1803) and Rastrelliger kanagurta (Cuvier, 1817) from the ring-net fishery in Tanga, Tanzania. A total of 1 434 and 320 stomachs of S. commersonnii and R. kanagurta respectively were examined for gut contents using the relative volumetric method. S. commersonnii was found to be a planktivorous carnivore, feeding principally on planktonic penaeid shrimps (48.6%), fish larvae (33.2%) and zooplankton (12.3%). R. kanagurta was found to be carnivorous, feeding predominantly on fish (60.6%), mainly S. commersonnii, while penaeid shrimps, juvenile fish, and juvenile stages of squids formed 26.5% of the total number of food items in R. kanagurta guts. Both S. commersonnii and R. kanagurta exhibited ontogenic diet shifts, where they fed exclusively on small prey as juveniles and consumed larger food items as they grew. The index of vacuity was higher in S. commersonnii (46.1%) than in R. kanagurta (16.6%). This study revealed the importance of penaeid shrimps as food for S. commersonnii, that in turn formed the main food for R. kanagurta. This implied that the two species were able to coexist in the same niche by avoiding interspecific competition for food.

Chironomid larvae are frequently available in the muddy habitats of Curzon Hall campus of University of Dhaka. The larvae of single species of  Chironomus (Insecta: Diptera) were collected from the drains and pond of the campus. Algae, fungi, diatoms, protozoan’s, rotifers, animal parts (crustacean appendages, ostracodan shell, insect appendages), and detritus were found as the  main food items of the larvae. Gut content analysis showed a change in their  feeding habits with seasons. The feeding intensity was maximum in spring just after winter. The feeding activity was lowest in winter. The variation in the diet  may suggest that these groups showed a low degree of selectivity, having more  generalist food selection habit. DOI: http://dx.doi.org/10.3329/bjz.v40i1.12902 Bangladesh J.
