Economic Viability of Polyculture of Nile Tilapia and Australian Redclaw Crayfish in Yucatan State, Mexico AgEcon
Ponce-Marban, Donny; Hernandez, Juan; Gasca-Leyva, Eucario.
Tilapia culture in rural communities of the state of Yucatan, Mexico, has been increasing in recent decades. Polyculture of tilapia with other more commercially valuable species is an opportunity to substantially improve the economic yields of rural producers. The economic viability of implementing a Nile tilapia with Australian redclaw crayfish polyculture was analyzed using profitability indicators such as internal rate of return (IRR) and net present value of the investment (NPV). A bioeconomic model was developed to simulate three production densities (33/0, 33/20, tilapia and crayfish, respectively), accounting for investment recuperation in time horizons of 5, 10 and 15 years. The model includes a biological sub-model describing the growth of...

Effects of blue shrimp Litopenaeus stylirostris and goldlined rabbitfish Siganus lineatus in mono- and polyculture on production and environmental conditions ArchiMer
Trung Cong, Luong; Lemonnier, Hugues; Hochard, Sebastien; Royer, Florence; Letourneur, Yves.
This study was conducted to compare the effects of shrimp and rabbitfish in mono- and polyculture stocked at high biomass on production and environmental conditions in a mesocosm system. Shrimp (14 g) and/or rabbitfish (19 g) were stocked in four treatments with different density but with the same total biomass (236 g m−2), including shrimp monoculture (SM) (17 shrimp m−2), shrimp–fish polyculture (SF) (11 shrimp and 4 rabbitfish m−2), fish–shrimp polyculture (FS) (6 shrimp and 8 rabbitfish m−2) and fish monoculture (FM) (12 rabbitfish m−2). After 10 weeks of experiment, shrimp survival and biomass were low in the treatments where shrimp were dominant (SM, SF), while rabbitfish survival and biomass were high in all the treatments. Shrimp mortality was...

Estructura y diversidad arbórea en sistemas agroforestales de café en la Sierra de Atoyac, Veracruz. Colegio de Postgraduados
García Mayoral, Luis Eduardo.
La Sierra de Atoyac se encuentra dentro de las áreas consideradas prioritarias para la conservación de la biodiversidad en Veracruz, en esta región la pérdida de la vegetación original es amortiguada por algunos sistemas agroforestales de café (SAF-café) que conservan un número considerable de especies arbóreas. Para fundamentar lo anterior se caracterizaron tres SAF-café: rusticano (RU), policultivo complejo (PC), policultivo simple (PS), así como una selva mediana subperennifolia (SM), al establecer tres unidades de muestreo (UM) por sistema, en dos franjas altitudinales (600-900 y 900-1200 msnm) para un total de 24 UM de 600 m2 cada una, en donde se registraron todos los árboles con un diámetro normal (DN) ≥ a 2.5 cm. Se calcularon índices...

Experimental evaluation of co-culture of juvenile sea cucumbers, Holothuria scabra (Jaeger), with juvenile blue shrimp, Litopenaeus stylirostris (Stimpson) ArchiMer
Purcell, S; Patrois, Jacques; Fraisse, N.
The co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or 'sandfish', with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in tanks with enriched sand substratum. Feed was supplied on trays, accessible only to shrimp. Survival of shrimp and sandfish was high in all treatments (73-100%). Growth of shrimp did not differ between monoculture and co-culture, but sandfish grew significantly slower in co-culture (P=0.03), although their sand burying and surface foraging were apparently unaffected by shrimp (P=0.76). However, shrimp increased the levels of total ammonia-N in tanks, which related inversely with sandfish growth (P=0.04). Conversely, sandfish did not appear...

Feasibility of polyculture of blue shrimp Litopenaeus stylirostris and goldlined rabbitfish Siganus lineatus in a mesocosm system ArchiMer
Luong, Trung Cong; Hochard, Sebastien; Royer, Florence; Lemonnier, Hugues; Letourneur, Yves.
The study was conducted to (1) estimate the effects of polyculture of blue shrimp Litopenaeus stylirostris with goldlined rabbitfish Siganus lineatus on production, environmental quality and water and sediment metabolism and (2) to determine if blue shrimp and goldlined rabbitfish polyculture is possible. The experiment was carried out for 12 weeks in a mesocosm system that consisted of 12 circular outdoor mesocosm fiberglass tanks (1.7 m2, 1275 L water volume). Shrimp (2.9 g) were randomly stocked at density of 15 shrimp.m− 2 without rabbitfish (control), with rabbitfish (25.5 g) at low density (1.2 fish.m− 2) (LDRB) and high density (2.4 fish.m− 2) (HDRB). Results indicated that goldlined rabbitfish S. lineatus did not affect shrimp growth performance....

Les systèmes intégrés en aquaculture marine : une solution durable pour un meilleur respect de l’environnement littoral ArchiMer
Hussenot, Jerome.
The former extensive polyculture systems of marine fish farming, are today replaced mainly by intensive monoculture systems (salmon, shrimp). These systems, multiplied in the same coastal zone, can present a significant environmental impact. To treat and value fish farming effluents, new integrated systems were constructed and tested to different scales. Some examples of land- and seabased systems around the world are presented, in particular the European project of innovation "Genesis" in which several French public and private, national and regional organisations are participants (IFREMER, Regional Centre of Experiment and Aquacultural Applications in Poitou- Charentes, IDEE). Recommendations are supplied to promote the development of the integrated fish...

Microbial control of the culture of <i>Artemia</i> juveniles through preemptive colonization by selected bacterial strains OMA
Verschuere, L.; Rombaut, G.; Huys, G.; Dhont, J.; Sorgeloos, P.; Verstraete, W..
The use of juvenile <i>Artemia</i> as feed in aquaculture and in the pet shop industry has been getting more attention during the last decade. In this study, the use of selected bacterial strains to improve the nutritional value of dry food for <i>Artemia</i> juveniles and to obtain control of the associated microbial community was examined. Nine bacterial strains were selected based on their positive effects on survival and/or growth of <i>Artemia</i> juveniles under monoxenic culture conditions, while other strains caused no significant effect, significantly lower rates of survival and/or growth, or even total mortality of the <i>Artemia</i> . The nine selected strains were used to preemptively colonize the...

Performance of Clarias gariepinus in a polyculture with Oreochromis niloticus. OceanDocs
Oladosu, G.A.; Ayinla, O.A.; Onuoha, G.C.; Needom, J.G..
A study of the performance of Clarias gariepinus (African Mudfish) in a polyculture with Oreochromis niloticus (Tilapia), integrated with broiler chicken production was carried at the African Regional Aquaculture Centre, Nigeria. Three experimrntal treatments were utilized. Treatment I was a polyculture of C. gariepinus and O. niloticus integrated with broiler chicken production, with application of supplemental feed to fish. Treatment II was a repeat of treatment 1, except that no supplemental feed was applied to fish, while treatment III was a polyculture of the two fish species per se with application of supplemental feed to fish. Results showed that the final individual weight, individual weight gain and recovery rate were best for C. gariepinus,...

Polyculture trial of mullets (Mugil spp) tilapia sp.,hemichromis sp. and elops sp. OceanDocs
Anyanwu, P.E.; Awa, J.N..
Polyculture trial of selected cultivable fin fishes was conducted at the Institute’s experimental fish farm Ikoyi, Lagos from April 1983 to January 1984. The species, Mugil spp; Tilapia spp; Hemichromis fasciatus and Elops lacerta gave a total annual production range of 1219 kg to 1441 kg per hectare (extrapolated). Tilapia species had the highest growth potential constituting 80% of the total harvest. Supplementary diet used was food left over (waste) from selected big hotels in Lagos. Elops lacerta (predator) recorded the highest average body weight of 415.88g while the lowest weight 62.14g, was recorded for Mugil spp. Tilapia spp and Hemichromis fasciatus had average body weights of 72.5g and 6.7 0g respectively.
