Abstract. Hasim, Tuheteru J, Fazrin DN. 2021. Comparison of growth pattern, condition factor, gonadosomatic index of Manggabai (Glosogobius giuris) and Payangka (Ophieleotris aporos) in Limboto Lake, Gorontalo, Indonesia. Biodiversitas 22: 3388-3393. Manggabai and Payangka are endangered native fishes in Limboto Lake due to continuous degradation in the lake. In addition, silting lake along with its area that continues to narrow can threaten the life of both fishes although the government has stipulated restoration of Limboto Lake as the ecosystem of the fishes. However, the current information on the fishes remains considerably limited in terms of making it as a conservation strategy. This study aims to analyze the relationship between the total length and weight of Payangka and Manggabai. Furthermore, it analyzes the condition factors and the gonadosomatic index of the two fishes. The research method integrates survey and laboratory techniques. The fishes are collected by using trap made of bamboo and motorcycle tires that are installed for three days and the catches are 60 fishes including 30 Manggabai and 30 Payangka. Then the total length and weight of the fish and their gonad weight were measured. Data analysis used mathematical formulation of the relationship between total weight and length, condition factor, and gonadosomatic index. The result of the analysis shows that the growth pattern of the Manggabai was negative allometric whereas the Payangka was positive allometric. The condition factor for both types is generally less than 1.7. The gonadosomatic index of Manggabai ranges from 4.10-20.00% and Payangka ranges from 0.05-1.98%. These conditions indicate that differences in growth pattern, condition factor, and gonadosomatic index are different forms of response to environmental conditions and in the spawning season of both types of fish.

The investigation of length-weight relationship and condition factor are very relevant indices to ascertain the health of fish in the water body. Length-weigh relationship and condition factor of Hyperopisus bebe (Lacepede, 1803) (Actinopterygii: Osteoglossiformes: Mormyridae) in River Galma, Zaria, Kaduna State, Nigeria, were assessed. The mean length and mean weigh in male and female were 26.703 cm +/- 0.51 cm and 25.32 cm +/- 0.898 cm; 158.2 g +/- 10.1 g and 95.91 g +/- 9.26 g, respectively. The exponent or growth pattern 'b' values for male and female were 2.009 and 2.176. The condition factor for male and female were 0.59 and 0.83, respectively. The negative allometric growth pattern and poor condition factor might be due to the poor water quality in the fish ecosystem and should be regarded with concern.

Abstract The objective of the present study was to examine the growth pattern and condition factors of the naleh fish, Barbonymus gonionotus Bleeker, 1849 in Nagan River, Nagan Raya District, Aceh Province, Indonesia. The sampling was conducted for 12 months from January 2016 to December 2016 using the explorative survey method. The sampling locations were determined based on the information given by local fishermen. A total of 761 fish samples were collected during the study. The Linear Allometric Model (LAM), Fulton’s and Relative Weight conditions factors were utilized to analyze the length-weight relationship and condition factor of the fish using growth parameters. The results showed that the highest coefficient of b was recorded in December, where the b value of males were 3.82 and 4.23 for the females with the average b value of males and females were 2.92 indicating an isometric growth pattern. The average Fulton’s condition factor (K) was 2.28 and the average Relative weight (Wr) condition factor was 100.59. It is concluded that fish had the isometric growth pattern and based on K and Wr value, the result implies that the waters are still in a good condition. Furthermore, the availability of food sources, low competitors, and low predators indicate that the aquatic environment is in a stable condition.

This study was carried out to evaluate the length-weight relationship, growth pattern and condition factor of the Silver catfish Chrysichthys nigrodigitatus from the Lower River Benue Makurdi, Nigeria. A total of 200 freshly caught specimens of C. nigrodigitatus were collected between July 2013 and September 2013 from the catches of the artisanal fisheries at landing points in Wadata Market, Makurdi. Results obtained showed that the “b” value for the males was 1.6067 while that of the females was 1.6791 and combined sexes 1.7371, indicating a negative allometric growth for this species. Correlation coefficient (r) obtained for males (0.9651), 0.9517 (females) and 0.9329 (pooled sexes) showed a positive significant relationship between length and weight of C. nigrodigitatus. Monthly mean condition factor (K), indicate that C. nigrodigitatus were in good physiological health condition. In conclusion, the baseline data on the length-weight relationship, condition factor of C. nigrodigitatus from the lower River Benue provided in this study is crucial in the sustainable management of this species in the River. Also, these findings will be useful in evaluating the population dynamics, stock and the aquaculture potential of C. nigrodigitatus for future purpose.

Length-weight relationships (LWRs) and condition factor are important biological information to assess the growth pattern and wellbeing of fish species influenced by numerous abiotic and biotic factors. To date, no data on the LWRs and condition of mullets in Sombreior River, Niger Delta. Hence, this research was conducted to determine abundance, length–weight relationship and Fulton’s condition factor (K) of three species of fish belonging to family Mugilidae in Sombreior River, Nigeria. There were a total of 248 samples from five sampling stations for a period of months. Fish species were of various sizes ranging from 24.66±0.40 to 26.35±0.26cm in length and 141.41±6.30 to 161.56±5.87g in weight. For the three species, slope (b) values ranged from 2.18 to 2.68 indicating a negative allometric growth of all fish species. The mean condition factor ranged from 0.89±0.03 forsix Mugil cephalus to 0.93±0.03 for Parachelon grandisquamis while the coefficients of determination (R2) of the LWR regressions ranged between 0.64 (Neochelon falcipinnis) and 0.79 (Parachelon grandisquamis). It was concluded that the mullets in the Sombreior River had a negative allometric growth pattern and the condition is showing the species were in good state of well-being since mean K values are  greater than 1.

The Relationship

The size composition, length-weight relationship, and condition factor of Thunnus albacares were examined in Bone Bay. Sampling was conducted at two stations, i.e., Station I at Cimpu in Luwu Regency and Station II at Lonrae in Bone Regency between July 2018 and June 2019. 10246 and 2651 yellowfin tunas were captured in Station I and Station II, respectively. Measurement of the fork length ranged between 20 cm and 192 cm with an average length of 81,257 ± 33,456 cm in Station I, and between 26 to 162 cm with an average length of 95,479 cm in Station II. The weight measurement ranged between 0,35 and 99,21 kg with an average of 14,539 kg in Station I, and between 0,46 and 97,35 kg with an average of 26,978 kg in Station II. Calculation of the relationship was based on the formula W= 5,5−5FL2,7454 (R2 = 0,963) in Station I, and W=4,1−5FL2,9103 (R2 = 0,761) in Station II. The values of condition factor at Station I and Station II were 2,1395 and 3,4374, respectively. It is quite evident that the growth pattern of the yellowfin tunas at Bone Bay was negatively allometric, indicating that the length increased faster than the weight.
