<b data-start=”1655″ data-end=”1711″><strong data-start=”1662″ data-end=”1711″>PROTOCOLOS DE SEGURIDAD DURANTE LA FUMIGACIÓN
<strong data-start=”1713″ data-end=”1741″>1. Planificación y aviso
<ul data-start=”1742″ data-end=”1986″>
Avisar con anticipación a todo el personal.
Restringir el área y <strong data-start=”1811″ data-end=”1878″>colocar señalización visible de “PELIGRO – FUMIGACIÓN EN CURSO”.
Solo personal <strong data-start=”1896″ data-end=”1922″>entrenado y autorizado puede manipular fumigantes (como fosfuro de aluminio o metilo).
<strong data-start=”1988″ data-end=”2015″>2. Equipos y materiales
<ul data-start=”2016″ data-end=”2263″>
<strong data-start=”2018″ data-end=”2049″>Traje de protección química, guantes de nitrilo, botas impermeables y careta o máscara con <strong data-start=”2113″ data-end=”2155″>filtro para gases tóxicos (tipo A o B).
En caso de fosfuro de aluminio: <strong data-start=”2191″ data-end=”2224″>prohibido usar agua o humedad (libera gas fosfina altamente tóxico).
<strong data-start=”2265″ data-end=”2285″>3. Procedimiento
<ul data-start=”2286″ data-end=”2519″>
Calcular correctamente la dosis y distribuir el fumigante según las recomendaciones del fabricante.
Mantener <strong data-start=”2399″ data-end=”2429″>ausencia total de personas durante el tiempo de exposición.
Monitorear la concentración del gas y controlar fugas.
<strong data-start=”2521″ data-end=”2551″>4. Ventilación y reingreso
<ul data-start=”2552″ data-end=”2789″>
Finalizada la fumigación, <strong data-start=”2580″ data-end=”2629″>abrir y ventilar completamente el silo o área durante el tiempo indicado.
Solo se permite el ingreso cuando el gas residual esté <strong data-start=”2715″ data-end=”2751″>por debajo del límite permisible (por ejemplo, <0.3 ppm para fosfina).
<strong data-start=”2791″ data-end=”2816″>5. Manejo de residuos
<ul data-start=”2817″ data-end=”2926″>
Recoger y neutralizar residuos de fumigante en un área ventilada y segura.
No desechar en agua ni suelos

Dear all as you must have gone through and we also discussed in length during course & Q & A session, that Carbon Nitrogen ratio is having good importance in maintaining pond water ecology. Now let us take this discussion forward for benefitting all the members of group,
1. What’s importance of carbon nitrogen ratio maintenance in normal pond culture?
2. What’s role of carbon and how is it become available in the pond?
3. Advisable Carbon Nitrogen (C:N) ratio in the normal culture?
4. What are the sources of adding up nitrogen to the dynamic pond culture?
5. How does this C:N ratio maintenance in culture ponds helps supporting fish / shrimp health?
Please mention your reply point-wise which ever for you are knowing and same time feel free to mention your point in case any additional to mentioned above 5 points.

Mr. Mohamed, Paul & Rotimi
Good to see your participation by appreciating the knowledge contribution of other fellow members.
Now I request you to go further and tell something about yourself,
1. how are you associated with Aquaculture,
2. which all species are you handling and
3. what type of culture patterns do you follow
4. what more improvement and betterment you are targeting and looking forward
Let’s have more of active and useful participation and knowledge sharing.

pH balance is crucial in fish culture because it directly affects the health, growth, and survival of fish, as well as the efficiency of the entire aquatic system.
Here’s a short, clear explanation 👇
Importance of pH Balance in Fish Culture
-
Fish Health and Survival
- Most fish thrive in a pH range of 6.5–8.5.
- Outside this range, fish experience stress, reduced immunity, and even death if extremes persist.
-
Toxicity Control
- Ammonia becomes more toxic at high pH, while metal ions (like aluminum) become more soluble and harmful at low pH.
- Maintaining proper pH keeps these substances in safer forms.
-
Efficient Biological Filtration
- Nitrifying bacteria that convert ammonia to nitrate function best around pH 7–8.
- Low pH can slow or stop the nitrogen cycle, leading to ammonia buildup.
-
Growth and Reproduction
- Stable pH supports enzyme activity, metabolism, and reproductive success in cultured species.
-
Water Quality Stability
- Balanced pH prevents sudden shifts that can shock fish and disrupt other water parameters (e.g., CO₂, alkalinity).
In summary:
Maintaining proper pH ensures a stable, healthy environment — reducing stress, improving growth, and supporting efficient waste breakdown in fish culture systems.pH balance is crucial in fish culture because it directly affects the health, growth, and survival of fish, as well as the efficiency of the entire aquatic system.Here’s a short, clear explanation 👇

Statistical Process Control (SPC) helps maintain consistent feed quality by monitoring key parameters:
- Pellet durability: Use X̄–R charts to track strength and detect variation due to moisture or ingredient issues.
- Mixing uniformity: Apply control charts to monitor ingredient distribution and ensure homogeneity.
- Milling particle size: Use I–MR charts to maintain consistent grind size and detect equipment wear.
Overall, SPC enables early detection of process deviations, reduces variability, and supports continuous improvement in feed manufacturing efficiency and quality.Short Summary:
