White shrimp (Litopenaeus vannamei) cultivation activities have developed rapidly in Indonesia. White shrimp aquaculture which is carried out intensively with high stocking densities has caused several problems, such as low survival and suboptimal growth. This study aimed to increase the growth, feed conversion, and survival of white shrimp through a combination of probiotics (Lactobacillus sp.) + turmeric flour (Curcuma longa) in feed. The method used in this study was Completely Randomized Design (CRD) with four treatment levels and three replications. The results revealed a significant effect (P0.05) on the value of the daily growth rate (DGR), absolute growth rate (AGR), specific growth rate (SGR), survival rate (SR), feed conversion ratio (FCR), and feed efficiency (FE), but no significant effect (P0.05) on the value of the absolute length rate (ALR). Giving probiotics 10 ml+5 g turmeric flour/kg feed (treatment B) was the best treatment for white shrimp aquaculture, including DGR, AGR, ALR, LPS, SR, FCR, and FE values. Furthermore, the results also revealed that increasing the concentration of turmeric flour in the feed, was negatively correlated to the growth and survival of white shrimp.

Kegiatan budidaya merupakan usaha untuk memperoleh ataupun membesarkan ikan yang salah satu faktor pendukung utama yaitu pakan, khususnya pada pakan buatan. Pemerintah pusat telah menciptakan program GERPARI (Gerakan Pakan Ikan Mandiri) yang bertujuan untuk menekan biaya pakan hingga kurang dari 60% sehingga mampu mewujudkan budidaya perikanan yang tangguh dan mandiri. Tujuan dari penelitian ini yaitu 1) Menganalisis implementasi program GERPARI; 2) Menganalisis persepsi pembudidaya ikan dan stakeholder; 3) Menganalisis faktor pendukung dan penghambat dari program GERPARI di Kabupaten Tulungagung. Metode pengambilan sampel dilakukan secara purposive. Narasumber dalam penelitian yaitu kelompok pembudidaya ikan yang memperoleh bantuan GERPARI sebanyak 22 responden serta stakeholder (dinas perikanan) sebanyak 3 responden. Alat analisis menggunakan indikator policy output dan policy outcome. Hasil kesimpulan sebagai berikut : Terjadi ketidakberhasilan atas implementasi dari Program Pakan Mandiri (GERPARI). Persepsi yang timbul dari pembudidaya ikan dan stakeholder (dinas perikanan) 100% menyatakan paham terkait GERPARI karena memiliki kelebihan dan kekurangan dari penerapannya.Cultivation activities are efforts to obtain or raise fish, with one of the main supporting factors being feed, especially artificial feed. The central government has created the GERPARI program (Movement for Independent Fish Feed) aimed at reducing feed costs to less than 60%, thus enabling the realization of robust and independent fisheries cultivation. The objectives of this research are: 1) Analyzing the implementation of the GERPARI program; 2) Analyzing the perceptions of fish cultivators and stakeholders; 3) Analyzing supporting and inhibiting factors of the GERPARI program in Tulungagung Regency. The sampling method was done purposively. The informants in the study were a group of fish cultivators who received GERPARI assistance, totaling 22 respondents, and stakeholders (fisheries department) totaling 3 respondents. The analysis tool uses indicators of policy output and policy outcome. The conclusions are as follows: There is a failure in implementing the Independent Feed Program (GERPARI). The perceptions arising from fish cultivators and stakeholders (fisheries department) are 100% aware of GERPARI because its application has advantages and disadvantages.

Natural feed has emerged as an alternative to support production performance and the nutrients contained in fish meat. This study aimed to determine the effect of feeding silk worms (Tubifex sp.) in improving production performance, nutritional content, and gill histology of striped catfish fingerlings (Pangasionodon hypopthalmus). Silkworms were sourced from different origins, namely Group P1 (silkworms with dry food media), Group P2 (commercial silkworms), and Group P3 (wild silkworms). Silkworms were reared for 55 days and fed to catfish seed for 25 days ad libitum. Feeding had no significant effect on absolute length growth, total biomass, and feed conversion with worm feeding treatment (P1) with values respectively 2.3 ± 0.10%, 6.0 ± 0.38%, and 4.2 ± 0.47%. Likewise, the results of growth rate, weight, and length, group P1 had better results compared to treatments (P2) and (P3) but were not significantly different. The best protein efficiency ratio resulted from treatment (P1) of 0.42 ± 0.25%. Gill histology changes were shown in groups P2 and P3, namely hemorrhage and congestion. Based on these results, silkworms reared in dry media can be an effective natural food for striped catfish fingerlings.
