“…In fact, the tolerance of eggs to changes in temperature has a posterior influence on larval morphological development (Heming & Buddington ). Under natural conditions, the newly hatched larvae are almost static and vulnerable to any visual predator; if movement‐related structures are poorly developed, the probability of being preyed increases (Wieser ; Kjørsvik, Galloway, Estevez, Sæle & Moren ). In consequence, during the ontogeny, the development of organs associated with movement is prioritised to increase their chances of survival (Wieser ; Kjørsvik et al .…”

The effect of temperature on the development of yolk-sac larvae of European hake (Merluccius merlucciusL.) under laboratory conditions

et al. 2016

The effect of temperature (10, 13, 16, 19 and 22°C) on hatching, development and survival of yolk-sac larvae of European hake, Merluccius merluccius, was studied. At 22°C the experiment was suspended because all eggs died a few hours after incubation. Five morphological indicators of larval development (standard length -SL, yolk-sac volume -YSV, oil globule diameter -OD, body height -BH and body wet weight -BW) were analysed. SL, YSV, OD and BW of newly hatched larvae were biggest in size and weight at low temperatures (P < 0.05). Throughout the experiments, the rates of changes in SL, YSV and OD varied with temperature (P < 0.05). By contrast, BH and BW remained constant and did not show significant relationship with the effect of temperature (P > 0.05). The potential model showed that the SL growth rate varied from 0.05 to 0.08 mm day À1 from 10.5 to 19.5°C respectively. However, at all temperatures two growth phases were identified: a rapid growth phase followed by a slow one. Rapid growth rate in length and depletion in yolk-sac and oil globule occurred at high temperatures. After total YSV and OD consumption (death by starvation), larvae died between 8 and 14 days at 19.5 and 10.5°C respectively, reaching a maximum length of 4.3 mm at 10.5°C. Metabolic indices such as: lowest threshold temperature (T 0 ); effective larval development (D eff ); cumulative thermal units (TC) to complete larval development; the temperature coefficient on growth rate in length (Q 10 ) and the condition factor (K) were also studied.

Effect of cultivated copepods (Acartia tonsa) in first-feeding of Atlantic cod (Gadus morhua) and ballan wrasse (Labrus bergylta) larvae

et al. 2015

The aim of this study was to compare the nutritional composition and effects of short periods with cultivated copepod nauplii versus rotifers in first‐feeding. Atlantic cod (Gadus morhua) and ballan wrasse (Labrus bergylta) larvae were given four different dietary regimes in the earliest start‐feeding period. One group was fed the copepod Acartia tonsa nauplii (Cop), a second fed enriched rotifers (RotMG), a third fed unenriched rotifers (RotChl) and a fourth copepods for the seven first days of feeding and enriched rotifers the rest of the period (Cop7). Cod larvae were fed Artemia sp. between 20 and 40 dph (days posthatching), and ballan wrasse between 36 and 40 dph, with weaning to a formulated diet thereafter. In addition to assessing growth and survival, response to handling stress was measured. This study showed that even short periods of feeding with cultivated copepod nauplii (7 days) had positive long‐term effects on the growth and viability of the fish larvae. At the end of both studies (60 days posthatching), fish larvae fed copepods showed higher survival, better growth and viability than larvae fed rotifers. This underlines the importance of early larval nutrition.

“…Perbedaan kualitas dan kuantitas pakan yang diterima oleh larva akan memberikan perbedaan pengaruh pertumbuhan somatik meskipun memiliki latar belakang genetik yang sama (Kjorsvik et al, 2011). Kondisi nutrisi pakan yang dimakan larva tidak hanya akan memengaruhi perkembangan alat pencernaan, pertumbuhan, dan sintasannya, tetapi juga proses perkembangan tulangnya (rangka/karapaks) (Lall & Lewis-McCrea, 2007).…”

ABSTRAKAdanya molting death sindrom yang umumnya terjadi pada stadia zoea-5 ke megalopa dan ke krablet-1 pada kepiting bakau, Scylla olivacea, diduga berkaitan dengan ketidakcukupan nutrien yang dikonsumsi larva, sehingga perlu dicobakan penggunaan pakan buatan (mikro) pada stadia tersebut. Penelitian ini bertujuan untuk mendapatkan dosis optimum penggunaan pakan mikro (micro diet, MD) untuk mensubstitusi penggunaan nauplius Artemia (Art) dalam pemeliharaan larva kepiting bakau. Hewan uji yang digunakan adalah larva kepiting bakau stadia zoea-4-5. Hewan uji tersebut dipelihara dalam wadah bak fibre berisi air laut 150 L dengan kepadatan 12 ind./L. Perlakuan yang dicobakan adalah pemberian pakan uji berupa: nauplius Artemia sebanyak 100% (100% Art), nauplius Artemia 75% + pakan mikro 25% (75% Art + 25% MD), nauplius Artemia 50% + pakan mikro 50% (50% Art + 50% MD), nauplius Artemia 25% + pakan mikro 75% (25% Art + 75% MD), dan pakan mikro 100% (100% MD). Pemberian pakan uji dilakukan pada pagi dan sore hari selama 15 hari pemeliharaan (hingga larva mencapai stadia krablet-1). Hasil penelitian menunjukkan bahwa pada penggunaan nauplius Artemia 50% + pakan mikro 50% didapatkan sintasan krabet-1 tertinggi (5,6%) dan berbeda nyata (<0,05) dengan sintasan krablet pada penggunaan 100% nauplius Artemia (sintasan 2,4%) dan 100% pakan mikro (sintasan 2,1%). Bobot badan, lebar karapaks krablet, dan aktivitas enzim pencernaan relatif sama di antara perlakuan. Penggunaan pakan mikro dapat menggantikan 50% penggunaan Artemia dalam pemeliharaan larva (zoea-5 hingga krablet-1) kepiting bakau.KATA KUNCI: kepiting bakau; zoea-5; krablet-1; sintasan; pakan mikro; nauplius Artemia ABSTRACT:Substitution of Artemia nauplii with micro diet for mud crab, Scylla olivacea, larvae. By: Usman, Kamaruddin, and Asda Laining Cases of molting death syndrome generally occur on the transitional stage of zoea-5 to megalopa stage and to crablet-1 of mud crab, Scylla olivacea. It is suspected that the event could be related to nutrient insufficiency consumed by the larvae which can be supplemented using artificial diet (micro diet). This study aims to obtain an optimum dosage use of the micro diet (MD) to substitute the use of
