Abstract

The research aimed to sex ratio and size at first maturity of snakehead gudgeon at Bolano Sau Lake. The research was conducted at Bolano Sau Lake from August to December 2019. Snakehead gudgeon samples were obtained from the fishermen using a gillnet with a mesh size 2½-3½ inches. Sample analysis was carried out at the Water Quality Laboratory, State College of Fisheries and Marine, Palu. The difference in sex ratios of snakehead gudgeon used the Chi-square test, while the size at first maturity was estimated based on the Spearman - Karber method. Snakehead gudgeon caught on a gillnet in Bolano Sau Lake measuring 79-163 mm. The sex ratio between males and females is not balanced where males are more dominant in females. The size at first maturity was 119.19 mm. Suggestion minimum legal size > 120 mm. The use of gillnets in snakehead gudgeon fishing activities has an effect on the balance of male and females, but is very selective with size.

Abstract

Small scale capture fisheries is one of the leading sectors that drive the economy of Banggai Laut Regency. Fishing technology improved related to fishing efforts has an effect on the preservation of fish stocks resource in the area that it required management efforts. This study aims to determine the sustainability status of small scale fisheries in Banggai Laut Regency based on ecological, fishing technology, social and economic dimensions. The research was conducted from September to December 2017 in seven sub-districts in Banggai Laut Regency. In determining the sustainability status of each dimension, the Rapfish (Rapid Appraisal for Fisheries Sustainability) approach is used. Furthermore, in determining the attributes that had an influence on the sustainability performance of small scale capture fisheries, a leverage analysis is carried out. The results showed that the highest sustainability index was the economic dimension of 75.57 (good), the ecological dimension of 59.25 (good), and the lowest was the social dimension of 22.95 (very bad), the dimension of fishing technology was 22.62 (very bad). Remedial measures that must be taken to improve sustainability performance include improving law enforcement facilities and infrastructure at sea and empowering supervisory officers, limiting excessive use of FAD, providing subsidies to small scale fisheries, and regulating fishing areas between local fishermen and Andon fishermen.

Abstract

Orange-spotted grouper is one of the coral reef fish has the economic value and exploited by local fisherman. Information about the size structure and sex ratio are urgent to formulate a policy for sustainability. This research aims to analyze the size structure and sex ratio of the orange-spotted grouper in Kwandang Bay. The research was conducted from December 2016 to November 2017. Sampling is carried out twice a month for one year. The total sample of orange-spotted grouper used for the analysis of the sex ratio was 149 individuals. Sample of orange-spotted grouper collected from fish landed and middlemen (grouper traders) at the Kwandang Fishing Port. Data analysis applying chi-square. The results show that males bigger than females. The sex ratio of orange-spotted grouper is 87.25 % female, 7.38 % male, and 5.37 % hermaphrodites. Orange-spotted grouper dominated by females and undergoes a gonad differentiation to male (protogynous hermaphrodite). It is concluded that The size of the male orange-spotted grouper is larger than that of the female grouper. The caught orange-spotted grouper is dominated by the female phase and undergoes a differentiation of the gonad from female to male (protogynous hermaphrodite)

Abstract

Reproductive biology is one of the biological aspects that needed to formulate responsible management of blue swimming crab (BSC). The crab is one of the commercial fisheries commodities in South Sulawesi, Indonesia. Presently no information on the reproductive biology of this crab from Spermonde Archipelago, Sout Sulawesi. Therefore, the study aimed to analyze and compare gonad maturity stage(GMS)andgonadalsomaticindex(GSI)oftheBSCcaughtonthreeecosystemsnamelycoralreef,seagrass,andmangrovein Salemo Island, Spermonde Archipelago. GMS and GSI were analyzed descriptively for five months from March to July 2015. Results indicate there was a difference in GMS of the BSC caught in mangroves, seagrass, and coral reef. Generally, mangrove was dominated by immature BSC with GMS I and GMS II, while the BSC caught in the seagrass and coral reef BSC were dominantly mature and spawn GMS III, IV, and V. GSI BSC caught in mangrove ecosystem are smaller than GSI BSC caught in seagrass and coral reef ecosystems. Seagrass and coral reef ecosystems suitable for development no-take zone of the BSC.

Abstract

Variasi suhu air memengaruhi pertumbuhan dan fisiologi organisme ektotermal secara langsung, termasuk ikan. Studi ini dilakukan untuk mengevaluasi pengaruh suhu air pemeliharaan terhadap performa pertumbuhan dan respons fisiologis benih Tor tambroides. Penelitian ini menggunakan rancangan acak lengkap (RAL), terdiri atas empat perlakuan suhu berbeda (24°C, 26°C, 28°C, dan 30°C) dan tiga ulangan. Benih Tor tambroides (panjang total 4,18 ± 0,32 cm; bobot tubuh 0,66 ± 0,03 g) sebanyak 15 ekor dipelihara per akuarium (dimensi 40 cm x 40 cm x 40 cm; volume air 40 L) dilengkapi dengan sistem aerasi dilengkapi dengan heater. Hasil penelitian menunjukkan bahwa perlakuan suhu air pemeliharaan berbeda memberikan pengaruh yang nyata (P<0,05) terhadap kinerja pertumbuhan (pertumbuhan mutlak dan laju pertumbuhan spesifik, sintasan) dan respons fisiologi (kadar hemoglobin) benih Tor tambroides. Perlakuan dengan suhu 28°C pada benih Tor tambroides menghasilkan bobot tubuh mutlak (1,01 ± 0,30 g) dan laju pertumbuhan spesifik bobot tertinggi (3,18 ± 0,14% hari-1), sintasan (99,37 ± 1,25%), dan rasio konversi pakan (FCR) terendah (0,94 ± 0,04). Kadar hemoglobin dan hematokrit tertinggi pada suhu pemeliharaan 30°C. Hasil penelitian mengindikasikan bahwa suhu air pada 28°C merupakan suhu efisien untuk pemeliharaan benih Tor tambroides.Water temperature directly affects the growth and physiology of ectothermic organisms, including fish. Hence, the experiment was conducted to study the effect of temperature variation on growth performance and physiological response of Tor tambroides juveniles. This study used a completely randomized design (CRD) with four temperature treatments (24°C, 26°C, 28°C, and 30°C) arranged in triplicates. There were 15 Tor tambroides juveniles (total length 4.18 ± 0.32 cm; body weight 0.66 ± 0.03 g) reared in each aquarium (dimensions 40 cm x 40 cm x 40 cm; water volume 40 L) equipped with an aeration system and a heater. The results showed that different rearing water temperatures had a significant effect (P<0.05) on the growth performance (absolute growth, specific growth rate, and survival rate) and the physiological response (hemoglobin value) of the Tor tambroides fingerlings. Tor tambroides fingerlings reared with temperature setting at 28°C showed the highest absolute body weight (1.01 ± 0.30 g) and highest specific growth rate of weight (3.18 ± 0.14% day-1), survival rate (99.37 ± 1.25%), and the lowest FCR (0.94 ± 0.04). The highest hemoglobin and hematocrit levels of the juveniles were found at 30°C. The study showed that the water temperature at 28°C was effective for rearing Tor tambroides fingerlings.
