season in Bangladesh for this fish species. 4). Month-wise food consumption showed that the algae was consumed throughout the year (Table 2). All the eggs were separated from each other with needle and measured along their longest axis under a stereo microscope. Bangladesh J. Sci. The success of any fish species is ultimately determined by the ability of its members to reproduce successfully in a fluctuating environment. After the commencing of the experiment, A. mola bred first time in the month of May in big hapa (Fig. The effects of 5 treatments for sex ratio and 3 treatments for photoperiod on fecundity and fry survival have been surveyed. Some biological characteristics, gonad weight, Gonadosomatic Index (GSI) and condition factor (K) of both sexes were observed. The concentration of nitrate-nitrogen (NO3-N) and nitrite-nitrogen (NO2-N) were determined by HACH kit (DR-2010, a direct reading spectrophotometer) using NitraVer-6 and NitriVer-3 powder pillow. Euglenophyceae for this fish species. Das and Dewan37 examined average mean length (6.5 cm) and weight (2.78 g) of A. mola in both sex which was more or less near about the present study. The number of samples is 200, taken four times in two months (April to May 2018). Yeamin Hossain Abstract Biological aspects including size at sexual maturity, breeding season and condition factor of Amblypharyngodon mola is a popular food fish of Indian sub-continent due to its high nutritional value. The fluctuation of condition factors in different groups may be attributed to spawning and following recovery, gonadal development and also on the general condition of seasonal apetite46. The results obtained go some way to explain the variety of parental care behaviour observed in fish, in particular the high frequency of male care, although further work is required to explain the exact patterns observed. Mondal and Kaviraj48 have documented fecundity range of 3,785-12,590 for the A. mola. In this respect, increasing the proportion of SIS production plays a key role, because SIS require no external feed under current production methods 23, Research and Extension under ICAR sponsored Project NICRA - Govt. The mean values of condition factor (K) in male A. mola were found from 0.910±0.030 (September, 2012) to 1.079±0.087 (April, 2012) (Table 3). Fractional spawning behavior along with asynchronous oocytes development has also been observed and the mortality of some A. mola broodfish within a short period after breeding has development speculation that the broodfish of A. mola die after breeding. However, when the proportion of highly nutrient-dense small indigenous fish species (SIS) was increased to at least 30% of the total output in any of the 14 aquaculture production systems analysed, these systems were able to meet or surpass the nutrient densities of average wild-capture fisheries. Sex-ratio, length at first sexual maturity, cycle of gonadal maturation and spawning periodicity has been studied as part of this study. Usually, more than 1g fishes were selected for gonad separation. However, consumption of algae was maximum in June (72.88%) and minimum in October (55.56%), just opposite to the consumption of aquatic plants. The breeding period of A. mola was with the ranges as mentioned by Parveen52, Hoque and Rahman49 and Saha et al.4. Se on sukunsa Amblypharyngodon tyyppilaji. Moreover, small fish is culturally acceptable, can be collected on small bulk and well-liked by most household members including children5,6. Introduction Fecundity literally means the potentiality of prolific breeding. When in the searching state, individuals find partners at a rate dependent on the proportion of members of the opposite sex searching. Various levels of external stress responses were noticed at 8 and 10 ppt salinity. Access scientific knowledge from anywhere. Morphometric and meristic study of Amblypharyngodon mola (Ham- Buch) from different habitats of Assam ... During the breeding season, the females acquire bulging abdomen. The mature ova were present all of the months except January which is similar with Gupta and Banerjee35. of India. The mean of ova diameter was 1.4 ± 0.35mm. and Myanmar (Talwar and Jhingran, 1991); also has. broods of the season, especially the first brood, whereas the cannibalism rate by 2 year‐old fish did not vary within the season. Some ecological parameters were also observed in the study areas. ), a herbivorous bottm feeder, feeds on algae, diatoms and higher aquatic plants. The 96-h median lethal salinity (MLS96 h) level of these fish was found out by exposing to saline water (0-10 ppt) in direct transfer method. In the early stages, it was difficult to separate them from each other. Salah satu sumberdaya di perairan tersebut yaitu ikan Selarkuning (Selaroides leptolepis). Availability, reproduction and breeding season: Available round the year, Peak breeding season monsoon, Gravid female found in May-July, fry available during June-August. Water quality: Temperature was found to range from 22.00-34.00°C during the experimental period in hapa. The age at first maturity was found to be at average length of 6.5 cm. of treatments were done 3 times.

According to Nikolsky23, male and female gonads have been grouped into different gonadal stages of development by using macroscopic and microscopic observation. First mature gonad of males was observed in April and available till October and the highest was observed in June and the lowest in November. Lacunae of information has been pointed out for further study mainly on age group wise variation in food preference and correlation of breeding periodicity with hydrological parameters and photoperiod. The SIS, “puti”, covering 10 species, with three (P. sophore, P. chola and P. ticto) being the most commonly consumed, both fresh and fermented, made DOI: 10.3329/bjsir.v44i3.4414 The size of the first time ripe gonad Yellowstripe scad male and female 189 mm.

Dissolved Oxygen and pH of water samples were measured by a HACH 40 d Multi-parameter. Misra and Jain47 have documented the fecundity of A. mola to be ranged from 1,210-16,072. The breeding period of the fish Amblypharyngodon mola was found to extend from March to October with three peaks, during March-April, June-July, and September-October. This species builds nests during breeding season and fries are found within the nests.

An intensive observation on the breeding biology may be further suggested in a large aquarium with close circuit camera. Breeding: The species is an egg scatterer which breeds three times each year, releasing around 500 eggs. These rates are defined to satisfy the Fisher condition that the total number of offspring of males equals the total number of offspring of females. Cycle of gonadal maturation has been studied by macroscopic and microscopic observation of the different maturation stages of gonad. This work could not have been done without the help of Lab Technicians and Field Staffs of Fisheries Field Laboratory, BAU, Mymensingh. The research was funded by the WorldFish through its “Cereal Systems Initiative for South Asia (CSISA-BD)” project. The relationship of fecundity with gonad weight was determined (Fig. Afroze and Hossain51 also observed August as the peak breeding season of A. mola. Females with immature gonads have been observed from December to May; the highest (100%) was observed in January while lowest in August. were not assigned for continuous field monitoring of this semi natural experimental culture setup; which could be considered as main limitation o f this study. The lowest mean fecundity of Mola in pond was 1023+625 and the highest was 6806±125 in size groups of 5.0-5.5cm and 8.1-8.5cm respectively. The fecundity ranged from 21 to 16867, while the relative fecundity ranged from 7 to 2122. Genus: Amblypharyngodon Species: A. mola. In male, the highest body weight, total length, gonad wt. were carried out at Rajshahi. ), Reproductive Biology of the Mola Carplet Amblypharyngodon mola (Hamilton) (Cypriniformes: Cyprinidae) from Netrakona Water, Project NICRA (Phase 1, 2015-2018): Impact of climate change on Indian inland fisheries and adaptation strategies. For 1 year‐old fish, which can enhance future reproductive success by growth and cannibalizing on early broods instead of mouthbrooding (at relatively low temperatures), this may be a tactic for investing energy in growth. All figure content in this area was uploaded by Sandipan Gupta, Aquaculture Research Unit, Department of Z. nutritional value (Alam et al., 2004; research work on this particular fish species. For fish 3 years, which have more breeding cycles and grow little, cannibalizing late broods may be energetic compensation for their poor somatic condition. Penelitian itu bertujuan untuk mengetahui karakteristik reproduksi ikan Selarkuning (Selaroides leptolepis) dengan melihat dari rasio kelamin jantan dan betina, pola pertumbuhan dengan faktor kondisi pada jantan dan betina, tingkat kematangan gonad (TKG), indeks kematangan gonad (IKG), ukuran pertama kali matang gonad, dan fekunditas. All, The waters of Manado Bay are areas that have a lot of biological resources. Cyanophyceae (7) and Bacillariophyceae (6) and 8 genera of zooplankton under Males and females were different in color, males were comparatively brighter than females. In both sex of A. mola, Hoque and Rahman49 observed five maturity stages (immature, maturing, immature, ripe and spent) whereas Azadi and Mamun24 have reported, female consists three gonadal maturity stages (immature, maturing and ripening). Reproductive biology of Amblypharyngodon mola was studied in Assam during the year 2009-2011. All rights reserved. 9a46bfee-69d4-4dcf-87a9-2cc42788d1f8 Editor's Picks. Mature gonad of females has been observed from May to November and the highest was observed in June and the lowest in December. In every month, about 5 to 20 fishes were recorded both male and female for the determination of reproductive characteristics. Prof. Dept. Therefore, periodic survey and monitoring of fish biodiversity, demarcation of breeding sites, field level research study on the efficacy of these fishes, and public awareness on establishment of larvivorous fish ponds should be adopted as a part of the vector management approach in the endemic malarious region of Ranchi district in Jharkhand, India. population. Results have revealed Amblypharyngodon mola as herbivorous fish and phytoplankton as the basic food group for this fish species; chlorophyceae has been observed as the most preferable food class. 44(3), 377-379, 2009, nvestigator: Dr. Uttam Kumar Sarkar , gonadosomatic index 1 mola were found in high quantities during late summer monsoon.
