Nursery performance and grow-out financial indicators of striped catfish, Muaro Jambi Kinerja penggelondongan dan indikator finansial pembesaran patin siam di Muaro Jambi

Abstract

This retrospective case study was conducted to describe the nursery performance of striped catfish (Pangasianodon hypophthalmus) juveniles and operating indicators of grow-out businesses in Muaro Jambi, Indonesia. Separate grow-out productivity and financial summaries from 2015 were descriptively analyzed with six nursery demonstration records summarized in a June 2025 evaluation. The datasets were not pooled and had different observation units. Stocking densities were 35-100 fish/m2. The harvest weight, culture duration, reported feed conversion ratio (FCR), survival and specific growth rate (SGR) of the six groups were 40.15 ± 8.55 g/fish, 59.83 ± 26.69 days, 0.92 ± 0.16, 83.38 ± 16.98% and 4.25 ± 1.71%/day (mean ± standard deviation between groups). Three groups were in the 40–50 g target interval, one was above the target, and two were below. Both below-target records were at 100 fish/m2 under documented water-supply constraints. Paired grow-out productivity records of three respondents in Kota Karang and six in Tangkit Baru. Annual changes in revenues were 0 to 28.00%. Annual changes in accounting profits were 17.24 to 47.32%. Annual changes in recalculated after adoption revenue-to-cost ratios were 1.28 to 1.35. Post-adoption costs are nursery and grow-out costs. Margins are for the integrated enterprise. Main limitations Small number of aggregate records, no within-group replication, unverified linkage of nursery and financial records, and observational design precluding causal attribution. Water supply planning, joint monitoring of growth and survival, and cycle-specific cost records are practical priorities.

Abstrak. Studi kasus retrospektif ini bertujuan menggambarkan kinerja penggelondongan juvenil ikan patin siam (Pangasianodon hypophthalmus) dan indikator operasional usaha pembesaran di Muaro Jambi, Indonesia. Enam catatan demonstrasi penggelondongan tahun 2015 dianalisis secara deskriptif, bersama data produktivitas dan ringkasan finansial pembesaran yang terpisah dan dihimpun dalam evaluasi Juni 2025; kedua kelompok data memiliki unit pengamatan berbeda sehingga tidak digabungkan. Padat tebar berkisar 35–100 ekor/m². Pada enam kelompok, bobot panen rata-rata 40,15 ± 8,55 g/ekor, lama pemeliharaan 59,83 ± 26,69 hari, rasio konversi pakan (FCR) yang dilaporkan 0,92 ± 0,16, kelangsungan hidup 83,38 ± 16,98%, dan laju pertumbuhan spesifik (SGR) 4,25 ± 1,71%/hari (rata-rata ± simpangan baku antarkelompok). Tiga kelompok mencapai kisaran target 40–50 g, satu kelompok melampauinya, dan dua kelompok berada di bawahnya; kedua catatan di bawah target berada pada padat tebar 100 ekor/m² dengan kendala pasokan air yang terdokumentasi. Catatan produktivitas pembesaran berpasangan mencakup tiga responden di Kota Karang dan enam responden di Tangkit Baru. Lima ringkasan finansial yang mewakili sembilan unit usaha menunjukkan perubahan pendapatan tahunan 0–28,00%, perubahan laba akuntansi 17,24–47,32%, dan rasio pendapatan terhadap biaya setelah penerapan nursery hasil hitung ulang sebesar 1,28–1,35. Biaya setelah penerapan mencakup nursery dan pembesaran; margin menggambarkan usaha terintegrasi. Keterbatasan utama adalah jumlah catatan agregat yang sedikit, tidak adanya ulangan dalam kelompok, keterkaitan catatan penggelondongan dan keuangan yang belum terverifikasi, serta desain observasional yang tidak memungkinkan atribusi kausal. Perencanaan pasokan air, pemantauan pertumbuhan dan kelangsungan hidup secara bersamaan, serta pencatatan biaya per siklus merupakan prioritas praktis.
