Effects of photoperiod and light intensity on initial swim bladder inflation, growth and post-inflation viability in cultured striped trumpeter (Latris lineata) larvae

The effect of a 24-hour photoperiod on the survival, growth and swim bladder inflation of pre-flexion yellowfin tuna (Thunnus albacares) larvae

“…Tandler and Helps (1985), Duray and Kohno (1988) and Trotter et al (2003) all reported significantly higher survival under continuous light for gilthead seabream, rabbitfish and striped trumpeter, respectively, although the gains in survival were not as great as those reported here for yellowfin tuna larvae.…”

“…Key environmental parameters to be considered for effective larval rearing include temperature and salinity (Fielder et al, 2005), the microbial environment (Harboe et al, 1994) and factors including turbulence, light intensity, light quality and photoperiod (Boeuf and Le Bail, 1999;Utne-Palm and Stiansen, 2002). Optimising photoperiod, for example, has been demonstrated to improve the performance of many species of marine fish larvae (Tandler and Helps, 1985;Duray and Kohno, 1988;Trotter et al, 2003); however, there appear to be no such published studies on tuna larvae. Lighting has, however, been shown to be of major importance in preventing high night-time mortalities caused by poor scotopic vision in early juvenile (30 DPH, 5 cm total length) Pacific bluefin tuna (Ishibashi et al, 2009).…”

“…As discussed by Trotter et al (2003), many physostomic fish larvae inflate their swim bladder at the water surface in darkness and continuous lighting can therefore inhibit this process. This appears to be the case with yellowfin tuna larvae, however swim bladder inflation in the control treatment was also relatively poor.…”

Influência do fotoperíodo no desenvolvimento de juvenis de tambaqui (Colossoma Macropomum)

“…Fotoperíodos longos (18HL:6HE e 24HL:0HE) proporcionaram melhores resultados no desenvolvimento de larvas de Latris lineatus do que o fotoperíodo mais curto (12HL:12HE) (Trotter et al, 2003).…”

Relationship between uninflated swim bladder and skeletal anomalies in reared gilthead seabream (Sparus aurata)

“…Anomalies in the activation and inflation of the swim bladder have been extensively described since the beginning of European aquaculture (Battaglene & Talbot, 1990;Bennet et al, 1987;Bulak and Heideinger, 1980;Chatain, 1986;Chatain & Ounais-Guschemann, 1990;Doroshev and Cornacchia, 1979;Giavenni and Doimi, 1983;Marino and Boglione, 1990;Nash et al, 1977;Paperna, 1978;Weppe and Bonami, 1983) but the aetiology of swim bladder inflation anomalies has not been fully determined, with culture conditions more commonly addressed as contributory factors. Many factors actually influence initial swim bladder inflation, such as air intake and surface access (Trotter et al, 2005;Woolley and Qin, 2010;Yamaoka et al, 2000), photoperiod and light intensity (Battaglene and Talbot, 1990;Fielder et al, 2002;Trotter et al, 2003;Woolley and Qin, 2010), temperature and larval body size (Marty et al, 1995;Trotter et al, 2003;Woolley and Qin, 2010) and salinity (Battaglene and Talbot, 1990;Woolley and Qin, 2010).…”
