“…However, live feeds such as Artemia nauplii , Daphnia manga , rotifers, copepods, among others, are still necessary for most larvae at feeding times. 49 – 51 According to Tancioni et al , 52 the growth rate of the brook chup ( Squalius cutemonis, Cyprinid) when fed rotifers between 10 and 20 DPH is 0.8%/day; when fed copepods (from 40-50 DPH), the growth rate slightly increases to 2.4%/day. The different feeding regimes have evident effects on larval performance.…”

Background: Mystacoleucus padangensis living in Lake Singkarak, Indonesia, has high potential market demand but is threatened by overfishing and has not been successfully cultured. This study describes the first broodstock development, induced breeding, and larval rearing of M. padangensis. Methods: A total of 1,000 female and 1,000 male broodfish were collected from the wild and reared in two concrete ponds (128 m2) at the Centre for Biodiversity Conservation, P.T. Semen Padang, Indonesia. The broodfish were fed commercial feed to satiation at 09:00 and 17:00 h. The females (average weight 7.56 ± 0.85 g) and males (4.86 ± 1.20 g) were selected at a ratio of 1:4 (female:male), and gonad maturation was induced with a single dose of GnRH analogue (Ovaprim) of 0.1 ml/fish. At 16 h after hormone injection, eggs were collected individually into a plastic vessel. Spermatozoa were collected with sterile syringes. Eggs were fertilized using the "dry" method, and 0.5 ml samples (equal to 100 eggs) were taken. The eggs were incubated in a plastic strainer with a water volume of 1.57 litres and placed in a tarpaulin pond with a volume of 150.72 litres. Results: The overall hatching rate was 78.93 ± 4.13%. The newly hatched larvae were 3900.81 µm long, with a yolk sac of 82881.480 µm2. The mouth opened at 72 days post hatching (DPH) with a gape measuring approximately 61.880 µm. The protocol of larval feeding started with artificial feed, followed by Artemia nauplii up to 30 DPH. Weaning of larvae started at 4 DPH. Larvae started metamorphosis by 15 DPH and ended by 22 DPH when the larvae reached 7430.27 µm. Larval rearing resulted in an average survival rate of 28.4 ± 3.04%. Conclusions: Its successful spawning induction and high larval hatching and survival rates make M. padangensis an excellent aquaculture candidate.

“…Similar results were also reported for some freshwater fish species in captive conditions. Rahman et al (2021) found that after 2 weeks of rearing, the larval survival of the Indian major carp ( Labeo rohita ) was positively correlated with female body weight but not with egg diameter. In contrast, Holtby and Healey (1986) reported no relationship between larval survival and female size in coho salmon, although larger females produced heavier eggs.…”

This study investigated the relationships among parental body weight, egg size and number, and offspring performance at the larval, juvenile and grow‐out stages of bighead catfish (Clarias macrocephalus) in Mekong domesticated (Can Tho; CT) and wild (Ca Mau; CM) strains. One‐year‐old broodstock from each strain were separated into two size groups, with those in the large (L) group having, on average, approximately double the body weight of those in the small (S) group. Both strains exhibited a strong linear increase in absolute fecundity (slope = 58.8, p < 0.01 for CT and slope = 52.3, p < 0.01 for CM) and a slight increase in egg diameter associated with increasing female body weight (slope = 0.0002, p = 0.03 for CT and slope = 0.0003, p = 0.06 for CM). However, there were no linear correlations between female body weight and yolk‐sac volume or larval body length at hatching (p > 0.05). Despite similar fecundities, the CM wild strain had larger eggs and more favourable larval properties than the CT domesticated strain (p < 0.01). However, these advantages did not result in better growth and survival of CM offspring at any stage. The CT strain showed improved growth in offspring with parents in the L group compared to those with parents in the S group across the three stages (35.7%, 50.0% and 43.9% respectively), while there was no significant increase in growth in the CM wild strain (p > 0.05). Parental body weight and strain had no effects on survival and feed conversion ratios (FCRs), with the exception that juveniles of the CM S group had the lowest SR (38.8 ± 6.0%) and FCR (1.09 ± 0.08) due to disease infection. The CT L group grew fastest and consumed the highest amount of food with similar feed efficiency to the other groups in juvenile and grow‐out stages (p < 0.05). These results indicated that the pertinence of ‘the bigger the better’ paradigm varied between growth stages in the two bighead catfish strains.
