Abstract

Salah satu kecamatan dengan produksi udang terbesar saat ini di Kabupaten Sumbawa adalah kecamatan labangka. Mengingat akan dikembangnya kegiatan tambak budidaya udang secara ekstensif di Kecamatan tersebut, maka perlu diketahui kondisi existing dari perairan laut di wilayah ini. Hal ini dibutuhkan sebagai bahan pertimbangan dalam pengelolaan tambak budidaya udang agar produksi udang serta kualitas perairan dapat terjaga. Salah satu indicator perubahan lingkungan perairan yang dapat diamati yaitu fitoplankton. Oleh karena itu, penelitian ini bertujuan untuk mengetahui kelimpahan fitoplankton dan parameter kualitas air lainnya di perairan laut Labangka sehingga dapat diketahui kondisi awal dari perairan laut Labangka sebelum dimulainya kegiatan pengembangan tambak udang di kawasan ini. Sampling plankton maupun air laut menggunakan purposive sampling. Analisis data Fitoplankton meliputi penghitungan kelimpahan (D), indeks diversitas (H’), indeks keseragaman E, dan indeks dominansi (D). Sedangkan parameter kualitas air yang diukur yaitu pH, total ammoniak, fosfat, nitrat, nitrit, dan BOT. Hasil perhitungan kelimpahan fitoplankton dan hasil pengukuran parameter kualitas air selanjutnya dianalisis secara statistik menggunakan korelasi Pearson untuk melihat hubungan antar variable yang diukur. Hasil pengamatan sampel fitoplankton menunjukkan bahwa terdapat 11 genera yaitu Coscinodiscus, Biddulphia, Nitzschia, Rhizosolenia, Pleurosigma, Triceratium, Ceratium, Pelagothrix, Trichodesmium, Dinophysis, dan Thallasionema. Selain itu, diketahui bahwa perairan ini masih dapat dikatakan aman karena kelimpahan fitoplankton terhitung kurang dari 15.000 ind/L. Sementara itu, nilai pH, total ammoniak, fosfat, nitrat, nitrit, dan BOT masih dalam kisaran aman walaupun ada parameter yang memiliki nilai melebihi baku mutu. Dapat disimpulkan bahwa perairan Labangka memiliki kualitas perairan yang baik dan sesuai untuk pengembangan kegiatan budidaya.

Abstract

West Nusa Tenggara (NTB) is one of the provinces that cultivates many Pinctada maxima pearl oysters. Seed dispersal is a stage that can influence the growth and activity of pearl oysters because they will be moved from the hatchery to the sea. The use of appropriate containers in pearl oyster seed dispersal very necessary to prevent pearl oysters from being carried away by currents or attaching biofouling as a nuisance to biota. The aim of this research is to determine the effect of rearing containers on the growth and survival of pearl oysters (Pinctada maxima). This research used an experimental method using a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments used are different types of keeping containers, namely using traditional containers, pocket baskets, waring baskets and lantern baskets. The results of the research showed that rearing pearl oyster spat (Pinctada maxima) for 60 days in Ekas Bay with the influence of different containers showed that the average absolute length growth obtained was 1.80-3.88 cm, the absolute weight ranged from 12.3 -31.10 g and survival rate 38.86 – 83.30%. The conclusion from this research is that using pocket baskets is better than other containers.

Abstract

Fisheries are an important sector in providing animal protein sources and supporting national food security. The success of fish reproduction is a crucial factor that determines the continuity of production and the sustainability of cultivation businesses. Zebrafish (Danio rerio) is a freshwater fish that is often used in biomedical research and reproductive biology due to its fast reproductive cycle, embryo transparency, and ease of maintenance process. The study was conducted for 45 days at Andar Farm Lingsar. The method used was an experimental Completely Randomized Design (CRD) consisting of 6 treatments and 3 replications, resulting in 18 experimental units. The treatments tested were a combination of various types of aquatic plants. The parameters measured included fecundity growth, fertilization rate, hatching rate, and gonadosomatic index. Data analysis was performed using ANOVA. If there were significant differences, Duncan's further test was used to identify significantly different treatments. The results showed that in the fecundity parameter, the Water hyacinth + cabomba substrate type produced the highest fecundity (117.6 ± 13.0 grains). In terms of Fertilization Rate (FR) and Hatching Rate (HR), the water hyacinth substrate produced the highest FR (79.96%), and HR (62.47%). Meanwhile, the Gonadosomatic Index (GSI) parameter also produced the highest results in the combination of water hyacinth + cabomba (20.4%). Water quality obtained during the study was within the optimal range with a temperature of 25-26 oC, Ph 7, and 6 mg/L.

Abstract

Salmacis sphaeroides is a species of sea urchin that plays an important role in economic and ecological aspects. However, high utilization rates by the public have led to a natural decline in population, This is provide a controlled environment that ensures a high-quality supply of sea urchin, reducing dependence on natural stocks. This study aims to analyze the effect of temperature differences on the rate of S. sphaeroides development, hatching rates, abnormality and survival rates of sea urchin embryo maintained by incubation of temperature, consisting of 5 treatments and 3 repeats. The method used in this research was an experimental method using the Complete Randomization Design. ANOVA tests showed that temperature had a significant effect on the hatch resistance, abnormality and survival of sea urchin larvae. Duncan continued testing. The results of research on embryonic development rates, hatching rate, abnormality and survival rates of sea urchins are significantly different. The best development and hatching rate is found at 28℃-30℃, the best abnormality at 28℃ with a value of 15.0±2.3 ᵃ and the best survival rate is also recorded at 28℃ with a value of 79.3±10.1 ᶜ. These results identify that temperatures of 28℃-29℃ can be recommended for sea urchin cultivation, taking into account the balance between egg hatches, abnormality and survival rate of sea urchin larvae.
