The paper provided the first data about age structure and growth of the Lataste’s toad, Bufotes latastii (Boulenger, 1882), from the Jammu and Kashmir State (India). The study of age structure of toads was carried out using skeletochronology. The minimal and maximal ages in males of B. latastii were 3 and 10 years, respectively, with mean age of 6.0 years. The majority of males (70%) were 5 or 6 years old. The age in females ranged from 4 to 10 years with mean value of 5.9 years. The majority of females (71%) were 4 – 6 years old. Males of B. latastii can reach maturation after three winterings and females after four winterings. The body length increment in males is 3.6 times, whereas in females is 3.7 – 4.0 times. After maturation, the growth rate is retarded and the individuals of different ages did not differ in its body length. In spite of maximal age of 10 years in both sexes, the largest male was 5 years old and the largest female was 4 years old.

The paper provides the first data about age structure and growth of the Zamda toad, Bufotes zamdaensis (Boulenger, 1882), from the Himachal Pradesh State (India). The study of age structure of toads was carried out using skeletochronology. The minimal and maximal ages in males of B. zamdaensis were 4 and 7 years, respectively, with mean age of 5.4 years. The majority of males (60%) were 5 years old. The age in females ranged from 5 to 9 years with mean value of 6.1 years. The majority of females (71%) were 5 – 6 years old. Males of B. zamdaensis can reach maturation after four winterings and females after five winterings. Unlike closely related species B. latastii, the growth rate in both sexes does not decrease significantly after the 1st and 2nd wintering and remains high after the 3rd and 4th wintering.

The growth performance of seve calves from different Mutura dams served by same bull was studied in a mini cattle ranch. Body measurements were taken and observed for growth over a period of 12 months. The result indicates an apparaent difference among the calves in all parameters measured including body weight, body length, height at withers and heratgirth. Growth rate also showed increased differences among the experimental calves. The birth weights of the seven calves ranged from 9.8 to 13.0kg, with a mean value of 11.42+0.44 while the yearling weights were between 107.80 and 129.48kg with an overall mean of 120.57+2.44. The coefficients of variation for body weight at birth and at 12 monthys were 10.16 and 5.36% respectively. The results further revealed that body weight at yearling age correlated positively with all parameters and these include body length (r=0.81889, r2 = 67.09), height at withers (r=0.8837, r2=78.09). Similarly, body length had a positive correlation with height at withers (r=0.9667, r2=93.45) and heartgirth (r=0.8782, r2=77.13). White height at withers correlated positively with heartgirth (r=0.9291, r2=86.42). Similar trends were obtained in the regression of each of the body measurements on the other in which body weight changes depended more on those of body length (0.56) than on heartgirth (0.34). Judging from the observed variations existing among the individual calves resulting from the different cows at birth and at 12 months of age, maternal rather than paternal influences appeared to be more important in the traits studied.

Data on age of mass maturing and biomass culmination for pacific herring from the Gizhiga-Kamchatka population in conditions of active fishery are presented. Dynamics of its age structure is considered for the periods before active fishery and after its renewal. After the fishery renewal, the portions of mature fish by age groups had increased and the age of mass maturing had decreased, the body length of mass maturing became smaller, the mean body length and weight had decreased for the majority of age groups, and the rate of maturing had increased for females. The established commercial measure corresponds well to recent biological structure of the population. There is concluded that the active fishery during five years has no negative impact on the state of the Gizhiga-Kamchatka population of herring.

The article consideres the dimensional and age structure, growth and coefficient of fatness of the bream Abramis brama in the Volga and the Kama reaches of the Kuibyshev reservoir in 2011-2014. In the period of bream spawning, according to Fulton, in May 2012 there was carried out accounting of sire species of bream in the reaches of the Kama, in the Volga reaches in May, 2013. However the average sizes of the body length of the bream statistically did not differ, and values of average mass of his body in the Kama reaches were higher. Fish age in the Volga reaches fluctuated between 2+…11+ years old, i.e. in the Kama reaches there were more species of older age. However, comparing age of the fish caught in 2012, one can see that the results in both places were equal, i.e. reproduction level differs very little. Dominating in catches of 2011-2014 were bream species born in 2004, 2005 and 2008. Among producers there were species of 2004-2005 generations. Growth of the bream in a phase of destabilization of an ecosystem of the Kuibyshev reservoir in comparison even with river conditions was slowed down. It can be noted that growth of the bream in a phase of destabilization of an ecosystem of the Kuibyshev reservoir in comparison even with river conditions was slowed down. In the Volga reaches even-aged individuals of the bream grow better, than in the Kama reaches where biomass of fodder benthos is lower. In the Kama reaches average sizes of fatness coefficient on Fulton are higher than in the Volga reaches.

About 2600 bullfrogs have been captured in three small lakes of the Laurentian region and 1863 among them have been marked and released. The study of the body length growth has been made by three methods (age lecture on pterygoïds, body length histograms, mark–recapture), which give concordant results: 59 mm at 1 year, 81 mm at 2 years, 108 mm at 3 years, 125 mm at 4 years, 137 mm at 5 years, 143 mm at 6 years. The biggest, measuring 162 mm, might have been 8 or 9 years old. The growth rate is the most important between 2 and 3 years, when bullfrogs reach sexual maturity. The body weight is 18 g at 1 year and 40 g at 2 years. At 3 years, the females weigh 101 g and the males 96 g. and at 5 years, the weights are respectively 215 and 194 g. Bullfrogs between 45 and 65 mm eat mostly in sects and the biggest ones eat mostly frogs, tadpoles, fish, and crayfish. The mating calls were heard by the end of May and the spawning occurs between the 20th of June and the 10th of July. The number of eggs (3 826 to 23 540) depends on the size of the individual. Sexual maturity is generally reached at 3 years when bullfrogs measure between 95 and 110 mm. However, some individuals reach sexual maturity at 2 years and some others at 4 years. Our results were compared with those of the literature.

<p>ABSTRACT</p><p><br />Growth rate of pearl goldfish juvenile Carassius auratus relatively slow to reach market size which will take approximately three months. To accelerate its growth can be done by providing exposure of the fish to low-power electric fields (10 V) via 3 ppt salinity water, with the goal of providing the close isoosmotic conditions, and also to streamline the flow of electricity from the electrodes to the body of the fish. This study aims to calculate the survival and growth rate of pearl goldfish juvenile of S sizes (2‒4 cm of body length) which were maintained at 3 ppt salinity water and treated by different exposure time of electric field (zero, two, four, and six minutes before feeding) with 10 volt electric power. Fish were cultured at a density of 2 fish/L in the (20×30×20 cm3) aquaria in volume of 6 L of water. Test fish had an average body length of 4.11±0.05 cm and the average body weight of 2.89±0.05 g. Exposure time of electric field were zero, two, four, and six minutes before the fish are fed, performed every day as much as three times i.e. morning, afternoon, and evening. The research design used was completely randomized design with four treatments, namely 0, 2, 4, and 6 (time for exposure is zero/control, two, four, and six minute) with three replications. The results show test fishes exposed to 10 volt electrical field for zero, two, four, and six minutes, have no significant effect on survival rate (P&gt;0.05). For growth performance, four minute exposure treatment gives the best results compared to controls (P&lt;0.05), supported by an increase in the percentage of the ratio of gut length to body length of the fish and higher feed efficiency.<br />Keywords: long exposure to the electric field, growth performance, pearl goldfish</p><p><br />ABSTRAK</p><p><br />Pertumbuhan benih ikan hias maskoki mutiara Carassius auratus relatif lambat, karena untuk mencapai ukuran jual memerlukan waktu sekitar tiga bulan.

In this paper we present results of laboratory reproduction of the Ladakh toad (Bufotes latastii) for three generations. Two pairs of animals, which were collected in April of 2013 in Jammu and Kashmir (India), became founders of a laboratory population. The first female gave offspring four times, while the second only once. The number of eggs in clutches obtained from the first female was 6804 – 10149 and from the second was 4080 eggs. Males, which were born in laboratory, started to vocalize at the age of 3 – 4 months after metamorphosis and at the age of one year successfully reproduced. Females become mature at the two-year age only. Thus, B. latastii is a fast-growing and early-maturing species. The number of eggs in clutches of 2-year-old laboratory females ranged from 31 to 6420 eggs (n = 28) and 3-year-old females from 19 to 6859 eggs (n = 21). Clutches were single- or double-row strings. The average thickness of egg strings was 3.2 – 5.9 mm. The diameter of eggs was 0.8 – 1.9 mm. The duration of embryonic development (until separation of pre-larvae from egg strings) was 2 – 5 days. The total body length of pre-larvae was 2.0 – 4.3 mm. The first larvae that started swimming and feeding were observed within 2 – 3 days after separation of pre-larvae from egg strings. The body length of larvae at the time of start of exogenous feeding was 2.9 – 4.3 mm and the length of tail was 1.6 – 6.3 mm. The total duration of embryogenesis was 4 – 8 days, larval development was 86 – 125 days, and overall development was 90 – 127 days.

Artemia salina is a natural feed that is widely used in fish and shrimp hatcheries due to its good nutritional content. This research was conducted in August 2019. This study aims to determine the effect of different types of feed on the growth rate of A. salina on a laboratory scale. The method used in this study was an experimental method that uses a completely randomized design (CRD) 1 factor with 3 levels namely, cornstarch (A), wheat (B) and tapioca (C). Water parameters show that the conditions was in good condition with average temperatures ranging from 28.1 - 28.7 oC, pH 8 and with a salinity of 60 ppt. Body length of A. salina ranged from 5.33 - 82.33 mm, where the body length in level A (cornstarch) was 82.33, level B (wheat) was 54.33, level C (tapioca) was 18, 67 and the control level is 5.33. The results of the ANOVA test for body length increase of A. salina showed p<0.05, that is 0.00. The survival rate of A. salina with different feed ranges from 0.5% - 88.50%, where the survival rate in level A (cornstarch) is 88.50%, level B (wheat) is 3.17%, level C (tapioca) is worth 51.50% and Control level is worth 0.5%. Survival rate in level A (cornstarch) is quite good. Based on ANOVA test, the survival rate between levels showed p<0.05, that is 0.00.
