Ikan uceng (Nemacheilus fasciatus) merupakan salah satu spesies ikan air tawar di Indonesia dengan nilai ekonomi cukup tinggi yang ketersediaannya masih mengandalkan penangkapan di alam, sehingga diperlukan upaya domestikasi untuk menjaga kelestariannya. Tujuan dari kegiatan ini adalah untuk mengamati biologi reproduksi dan pola pertumbuhan ikan uceng di lingkungan buatan (akuarium). Ikan uceng hasil tangkapan alam dari Sungai Progo, Temanggung, Jawa Tengah (panjang total 5,55 ± 0,53 cm; bobot 2,49 ± 0,24 g) diadaptasikan selama 12 bulan di akuarium (40 cm × 30 cm × 30 cm) dengan sistem air mengalir yang dilengkapi dengan aerator. Ikan uceng diberi Tubifex, hingga sampai akhirnya dapat beradaptasi dengan pakan komersial. Pakan komersial yang diberikan yaitu sebesar 3% per hari dari biomassa tubuh dengan frekuensi dua kali sehari. Data biologi reproduksi diperoleh melalui koleksi data panjang total, bobot badan, bobot gonad, fekunditas, diameter telur, dan indeks kematangan gonad. Data pola pertumbuhan diperoleh dengan koleksi data panjang, bobot, dan sintasannya. Hasil penelitian menunjukkan bahwa induk betina yang gonadnya berkembang mempunyai warna bintik hitam yang jelas, sebaliknya induk jantan warna bintik hitam memudar. Indeks kematangan gonad (IKG) yang diamati pada ikan uceng setelah 12 bulan pemeliharaan yaitu berkisar antara 0,007-0,027 pada jantan dan 0,13-0,25 pada betina. Kisaran diameter telur yang diamati yaitu berkisar antara 0,61-0,68 mm, dengan fekunditas 680-4.198 butir. Sedangkan pola pertumbuhannya menunjukkan bahwa ikan uceng betina dan jantan memiliki pola pertumbuhan allometrik negatif (b= 2,739 pada betina; b= 2,895 pada jantan). Nilai faktor kondisi Fulton (K) pada ikan uceng yang diamati yaitu 0,44-1,07 (rata-rata ± SD: 0,70 ± 0,11) pada betina dan 0,37-0,72 (rata-rata ± SD: 0,60 ± 0,06) pada jantan. Dari pengamatan ini ditemukan bahwa proses perkembangan kematangan gonad ikan uceng di akuarium lebih lambat dibandingkan ikan uceng di habitat aslinya.Barred loach (Nemacheilus fasciatus) is one of native fish species in Indonesia with high economic value, where their availability still depends on wild capture. Thus, domestication is needed to maintain its sustainability. The purpose of this study was to observe the reproductive biology and growth pattern of barred loach reared in aquarium (artificial environment). Fish were collected from Progo River, Temanggung, Central Java (total length of: 5.55 ± 0.53 cm; body weight: of 2.49 ± 0.24 g). The fish were reared for 12 months in aquarium (40 cm × 30 cm × 30 cm) with flowthrough system and equipped with aeration. The fish were fed with Tubifex until they accepted commercial feed. Then, the fish were fed twice a day at a ratio of 3% from the total fish biomass. The reproductive biology data were collected by measuring their total length, body weight, gonad weight, fecundity, egg diameter, and gonadosomatic index. Growth pattern were measured from length, weight, and survival. The results showed that matured female had shown black spot and male had inconsistent formation of black spots on their body. The gonadosomatic indexes ranged between 0.007-0.027 for male and ranged between 0,13-0,25 for female. The egg diameters ranged between 0.61-0.68 mm, with the fecundity of 680-4198 eggs. The result of observation on growth pattern showed that female and male had negative allometric growth (b= 2.739 for female, b= 2.895 for male). The value of Fulton condition factor (K) in the observed fish was 0.44-1.07 (mean ± SD: 0.70 ± 0.11) on female and 0.37-0.72 (mean ± SD: 0.60 ± 0.06) on male. From this study, it was found that gonad maturity development of barred loach reared in aquarium was slower than those in their natural habitat.

In comparison to other nations, the Nepalese information on the reproductive biology of hill-stream fish is limited. So, the purpose of the present study was to provide information related to reproductive biology of a hill-stream sucker throat catfish Pseudecheneis sulcata from the snow-fed Tamor River, Nepal. The study was carried out from June 2018 to May 2019.  A total of 57 female fish was collected. The fecundity of 22 females was assessed, while the gonadosomatic index was determined using all the collected samples. The absolute fecundity ranged from 2,316 to 7,597 eggs, with an average of 3,660 ± 210. This range of absolute fecundity indicates that Pseudecheneis sulcata is a moderately fecund fish when compared to certain low fecund species and some exceptionally fecund fish with tens of thousands of eggs. Relative fecundity ranged from 65.47 to 129.11 with a mean of 88.98 ± 4.35. The present study demonstrated that absolute fecundity was moderately correlated with total length (r = 0.45) and strongly linked with body weight (r = 0.78), and ovary weight (r = 0.80). Mean gonadosomatic index (GSI) was recorded the highest in January (15.7 ± 1.22%), and showed a decrease in the subsequent month of February (10.3 ± 0.75%), March (6.25 ± 0.28%) and April (1.66 ± 0.40%). The trends of GSI might have indicated that the sucker throat catfish was a batch spawner, with spawning season occuring between January and March.

This study provides information on the reproductive biology of the coral catshark caught in the waters around Seribu Islands, Indonesia. A total of 257 coral catsharks were collected from February 2017 to January 2018. The total length of coral catshark ranged from 170 to 585 mm for females and 255-575 mm for males, respectively. The total weight of females ranged from 85 to 640 g and males from 100 to 620 g The sex ratio between females and males was 0.45 and it was not significantly different from the expected 1:1 ratio. The growth pattern of coral catsharks in Seribu Island was negatively allometric and the population was dominated by mature sharks. The mean size at first maturity was estimated to be 557 mm for females and 514 mm for males, based on to the relationship between the proportion between maturity stage and total length. The ovulation season was estimated occur from October to March, whereas September to April was mating season based on monthly variations of gonadosomatic index (GSI) values and the occurrence of egg cases in uterus.

Menticirrhus littoralis is an important sport and commercial fish species in southern Brazil. This paper aims to analyze the reproductive biology of the species in Rio Grande do Sul coastal waters. Captures were carried out at Cidreira's fishing pier (30º 08' S; 50º 11' W) located on the Northern Coast of Rio Grande do Sul, where sport-fishing takes place throughout the year. Sport fishermen using hook-and-line with different hook sizes and varied baits exclusively made the captures. A total of 807 individuals were obtained from June 1997 to May 1998. Sexual proportion was 0.67 female for each male (323 females and 484 males; chi2c = 32.120; DF=1; P<0.001). The smallest individual (total length) for captured animals was a male of 13 cm whereas the largest was a female of 46 cm. The minimum size (total length) for a mature female was 19.8 cm. The size at first maturation (L50) was 23 cm and females larger than 27 cm spawned at least once (L100). The reproductive period for M. littoralis is from September to March. Gonadosomatic index (GSI) showed a clear seasonal pattern. Mean ovarian weight was highest in November when it reached 5% of total body weight. Apparently, there is a size gradient for M. littoralis in the area. Larger individuals inhabit deeper water, and they move to the coast mainly for spawning.

The aim of this tudy was to evaluate corporal and testicular development in wild boars (Sus scrofa scrofa) from birth to 12 months of age, evaluating body weight, biometric testicular parameters, and gonadosomatic index. Thirty-nine male wild boars from a commercial farm licensed by IBAMA were used in the study. The animals were weighed and assigned to 13 experimental groups. The testes were recovered through unilateral orchiectomy, weighed on an analytical balance and measured for length, width and thickness. Body weight and testicular measures increased with the age, up to 12 months, and were more accelerated in the first and ninth months. Initially the testicular growth pattern, between zero and nine months, followed the body growth, and the gonadosomatic index varied from 0.07 to 0.09%. Between 9 and 11 months, the testicular growth was superior to the body growth, and the gonadosomatic index varied from 0.09 to 0.16%. Finally, after 11 months of age, testicular and body growth had a similar behavior. In conclusion, body weight, testicular biometry, and gonadosomatic index development accelerated in the ninth month.

Abstract The gonadosomatic index (GSI) and fecundity of the threatened Cirrhinus reba (Hamilton) was studied over a period of one year from January to December 2015 in the Ganges River (northwest Bangladesh). The GSI index indicated that the C. reba breeding season in the Ganges was from June to September with the peak in August. Fish fecundity increased with increasing fish length and weight, and the highest fecundity (265,042.23) was recorded in a fish with a total length, a body weight, and an ovary weight of 23.80 cm, 136.00 g and 45.00 g, respectively. There was a linear relationship between fecundity and total length (r = 0.871), body weight (r = 0.872), and ovary weight (r = 0.879), with that between ovary weight and fecundity being the strongest.

Eksploitasi ikan lalawak (Barbonymus balleroides) yang berlebihan dari alam mengakibatkan langkanya jenis ikan ini di beberapa perairan aslinya. Sebelum ikan ini diperkenalkan sebagai komoditas budidaya, masih diperlukan lebih banyak lagi informasi mengenai aspek bioreproduksi ikan lalawak yang telah dipelihara pada lingkungan budidaya. Tujuan dari kegiatan ini adalah untuk mengevaluasi produktivitas ikan lalawak yang dipelihara pada lingkungan budidaya melalui pengamatan bioreproduksi dan hubungan panjang-bobot terhadap fekunditas. Sampel induk ikan lalawak betina yang diambil sebanyak 15 ekor, kemudian dipilih lima ekor induk betina yang telah matang gonad dengan ciri-ciri seluruh badannya terasa kasar apabila diraba, perut membesar ke arah posterior dan terasa lunak, genital mengembang, serta berwarna kemerahan. Data yang dikoleksi berupa panjang total, bobot badan, bobot gonad, fekunditas, diameter telur, dan indeks kematangan gonadnya. Hasil penelitian menunjukkan bahwa kisaran fekunditas ikan lalawak adalah 1.920-2.236 butir/g bobot gonad, dan 83-352 butir/g bobot badan induk dengan rata-rata diameter telur 0,87-1,10 mm. IKG berkisar 3,73%-18,36% dari kisaran bobot induk 85,32-264,8 g. Hubungan antara bobot badan dengan bobot gonad ikan lalawak digambarkan dengan persamaan linear y= 5,829ln (x) + 0,691 (r= 0,874); sedangkan hubungan panjang badan terhadap bobot gonad digambarkan dengan persamaan y= 28,52ln (x) - 38,10 (r= 0,7487). Pada ikan lalawak, hubungan bobot badan dengan fekunditas lebih erat dibandingkan dengan hubungan panjang badan terhadap fekunditas. Hasil pengamatan juga menyimpulkan bahwa ikan lalawak tergolong ikan yang memijah secara parsial.Over-exploitation of lalawak (Barbonymus balleroides) from its natural habitat had significant negative impacts on its availability. Before it is introduced as aquaculture commodity, more information about its reproductive biology in aquaculture environment needs to be well observed. The aim of this study was to determine the productivity of lalawak reared in aquaculture environment through observation of bioreproductionand relationship between fecundity and body length-weight of lalawak. Samplewas randomly taken from fifteen individuals female. From those samples, gonads were taken from five mature females for reproduction observation, by which the mature females were selected following specific criteria such as : their body feels rough if touched;enlarged abdomen posteriorly and felt soft; fluffy and reddish genital. Data collection consisted of measurement of the total length, body weight, gonad weight, fecundity, egg diameter and gonadosomatic index (GSI). The results revealed that the fecundity of lalawak ranged from 1,920 to 2,236 eggs/gof gonad weight and 83 to 352 eggs/g of body weight with average diameters of eggs ranged from 0.869 to 1.10 mm. GSI values ranged from 3.73 to 18.36% of 85.32 to 264.8g of body weight. The relationship between body weight and gonad weight of lalawak was described by the linear equation of y= 5,829ln (x) + 0.691 (r= 0.874), while the body length relationship to the gonad weight was described by the equation of y= 28,52ln (x) - 38.10 (r= 0.7487). Fecundity relationship with body weight of lalawak was closer than the length. The observations also concluded that lalawak is classified as partial spawning.
