Abstract

Spirulinia platensis adalah salah satu jenis mikroalga yang banyak dimanfaatkan untuk kegiatan pembenihan ikan sebagai pakan alami karena kandungan proteinnya yang tinggi. Tujuan studi ini adalah untuk mengetahui waktu panen yang tepat yang dilihat berdasarkan pola kepadatan sel S. platensis. Prosedur kerja kultur skala laboratorium ini digunakan wadah erlemeyer volume 2 liter. Skala intermediet dipelihara pada bak konteiner volume 60 liter dan berada di luar ruangan. Skala massal dipelihara pada kolam dengan volume 1.000 liter dan di luar ruangan. Pupuk walne digunakan pada skala laboratorium dengan dosis 0,5 ppm. Pada skala intermediet dan skala masal pupuk yang digunakan meliputi Urea, SP-36 dan ZA. Pengamatan kepadatan sel dan kualitas air seperti pH dan suhu dilakukan setiap hari. Analisis data yang digunakan adalah deskriptif yakni dengan menyajikan data dalam bentuk grafik dan tabel. Hasil studi pada skala laboratorium yakni fase eksponensial terjadi pada hari ke 3. Fase eksponensial pada kultur skala intermediet tidak terlihat karena kepadatan sel terus mengalami peningkatan sampai hari ke 10. Pada skala massal hari ke 9 dan 10 menunjukkan fase stationer. Selama pemeliharaan kualitas air pada skala laboratorium cenderung stabil 20-25 °C dan 7-7,3 sedangkan skala terbuka (intermediet dan massal) kualitas air mempunyai kisaran yang sangat luas 21-30 °C dan 7,0-8,5. Studi ini dapat disimpulkan bahwa waktu pemenan mikroalga untuk skala laboratorium yaitu hari ke-3, dan skala massal yaitu hari ke 7 atau ke-8.

Abstract

One of the issues in aquaculture activities is the high cost of commercial feed, and self-prepared feed can be one of the solutions. Efforts to improve feed utilization in cultured organisms include the use of stimulants known as attractants. The objective of this study is to observe the use of different attractant sources in self-prepared feed for whiteleg shrimp (Litopenaeus vannamei) by examining feed consumption, feed conversion ratio (FCR), and the growth of the shrimp. The treatments in this study consisted of feed without the addition of attractants (A), feed with the addition of squid meal attractant (B), shrimp head meal (C), and rebon (small shrimp) meal (D). Whiteleg shrimp (DOC 30) with an average weight of 2.96±0.21 g were reared in aquariums, with each treatment consisting of four replicates. After the rearing period, the feed intake for treatments A, B, C, and D was 0.156 g/shrimp, 0.184 g/shrimp, 0.181 g/shrimp, and 0.167 g/shrimp, respectively. The feed conversion ratio (FCR) obtained was 1.8, 1.4, 1.2, and 1.3, respectively. The absolute growth for the four treatments was 1.092 g/shrimp, 1.632 g/shrimp, 1.779 g/shrimp, and 1.506 g/shrimp, respectively. Statistical analysis showed no significant differences among the four treatments (P>0.05) in terms of feed consumption, FCR, and growth. The results of this study highlight the potential use of shrimp head meal, which is a waste product, as an attractant and a protein source.

Abstract

The commercially important red seaweed Kappaphycus alvarezii is extensively cultivated for carrageenan production. Despite its economic value, large-scale reproduction and genetic enhancement remain limited due to its low regeneration potential. This study aimed to optimize plant growth regulator (PGR) concentrations for efficient callus induction in K. alvarezii. A completely randomized design was employed, comprising five treatments with varying concentrations of indole-3-acetic acid (IAA) and 6-benzylaminopurine (BAP), along with a control lacking PGRs. A total of 180 explants from meristematic tissues of acclimatized thalli were cultured (30 explants per treatment). The highest callus induction rate (88%) was achieved with 1.50 mg/L IAA and 5 mg/L BAP (Treatment F), with visible callus formation beginning around day 38. A progressive color change from brown to white was observed, indicating active cellular proliferation. Other treatments exhibited lower induction rates, ranging from 0% (control) to 61% (Treatment D). These findings underscore the critical influence of auxin–cytokinin interactions on callogenesis and offer an optimized hormonal regime for improving in vitro culture efficiency. The established protocol provides a valuable platform for future large-scale propagation and genetic improvement strategies in K. alvarezii, contributing to the advancement of seaweed biotechnology.

Abstract

Cultivation of the seaweed Gracilaria verrucosa is necessary as a preventive measure against overexploitation. One applicable method is tissue culture, which requires special attention to nutrient needs to support accelerated growth. These nutrients can be provided through fertilization. One commonly used chemical fertilizer in seaweed tissue culture is Provasoli’s Enriched Seawater (PES). This study aims to determine the optimal PES fertilizer dosage for the production of G. verrucosa seedlings through tissue culture using a vegetative propagation method. This study used a completely randomized design with analysis of variance (ANOVA) consisting of four treatments of different PES fertilizer doses with three replicates for each treatment. The results showed that fertilizer dose variation did not significantly affect the absolute growth of explant weight, but tended to increase the number of growth points. Growth points began to increase in the second week for all treatments, and by the fourth week, the number of growth points at a 1.5% dosage showed a significant difference compared to other doses. The application of PES fertilizer in G. verrucosa seedling production through tissue culture with vegetative propagation indicates that different fertilizer doses do not affect explant growth but significantly influence the increase in growth points by the fourth week

Abstract

The availability of high-quality live feeds, such as Thalassiosira sp. and Chaetoceros sp., is a critical factor for the success of shrimp aquaculture; however, it is often constrained by fluctuations in growth performance and cell density at different production scales. This study aimed to identify the growth of Thalassiosira sp. and Chaetoceros sp. at laboratory, intermediate, and mass scales. The research was conducted using an experimental method with a Completely Randomized Design (CRD) with two treatments and three replications. The treatments were different microalgae species cultured at different production scales and compared. Cell density data and growth phases were analyzed statistically using SPSS. The results showed that Chaetoceros sp. had higher growth compared to Thalassiosira sp. The cell density range of Chaetoceros sp. was 1.1×10⁷ - 5.0×10⁷ cells/mL, while Thalassiosira sp. was 1.7×10⁶ - 5.2×10⁶ cells/mL. The growth rate of Chaetoceros sp. also reached the peak of the exponential phase faster at Day of Culture (DOC) 4 compared to Thalassiosira sp., which peaked at DOC 5. Water quality during the study across all production scales showed an optimal range for the growth of both microalgae species.

Abstract

This study employed a Completely Randomized Design (CRD) consisting of four treatments with three (3) replications, resulting in a total of twelve (12) experimental units: P1 0%, P2 0.10%, P3 0.20%, and P4 0.30%. The use of clove oil doses on shrimp seed survival during closed transportation showed significant differences among the treatment groups, where P < 0.05. Survival rates for each treatment were as follows: P1 at 53.1%, P2 at 87.9%, P3 at 88.7%, and P4 at 62.4%. Based on measurements of water quality parameters during the study, the conditions in the plastic bag containers after 24 hours of transportation remained within tolerance limits that support shrimp seed maintenance. The post-transport water quality values were: temperature 29.38–29.41°C, dissolved oxygen 4.70–4.75 ppm, and pH 7.30–7.39.
